Multipath device manageability improvements Update udev helper scripts to deal with device-mapper devices created by multipathd. These enhancements are targeted at a particular storage network topology under evaluation at LLNL consisting of two SAS switches providing redundant connectivity between multiple server nodes and disk enclosures. The key to making these systems manageable is to create shortnames for each disk that conveys its physical location in a drawer. In a direct-attached topology we infer a disk's enclosure from the PCI bus number and HBA port number in the by-path name provided by udev. In a switched topology, however, multiple drawers are accessed via a single HBA port. We therefore resort to assigning drawer identifiers based on which switch port a drive's enclosure is connected to. This information is available from sysfs. Add options to zpool_layout to generate an /etc/zfs/zdev.conf using symbolic links in /dev/disk/by-id of the form <label>-<UUID>-switch-port:<X>-slot:<Y>. <label> is a string that depends on the subsystem that created the link and defaults to "dm-uuid-mpath" (this prefix is used by multipathd). <UUID> is a unique identifier for the disk typically obtained from the scsi_id program, and <X> and <Y> denote the switch port and disk slot numbers, respectively. Add a callout script sas_switch_id for use by multipathd to help create symlinks of the form described above. Update zpool_id and the udev zpool rules file to handle both multipath devices and conventional drives.

Add vdev_id for JBOD-friendly udev aliases vdev_id parses the file /etc/zfs/vdev_id.conf to map a physical path in a storage topology to a channel name. The channel name is combined with a disk enclosure slot number to create an alias that reflects the physical location of the drive. This is particularly helpful when it comes to tasks like replacing failed drives. Slot numbers may also be re-mapped in case the default numbering is unsatisfactory. The drive aliases will be created as symbolic links in /dev/disk/by-vdev. The only currently supported topologies are sas_direct and sas_switch: o sas_direct - a channel is uniquely identified by a PCI slot and a HBA port o sas_switch - a channel is uniquely identified by a SAS switch port A multipath mode is supported in which dm-mpath devices are handled by examining the first running component disk, as reported by 'multipath -l'. In multipath mode the configuration file should contain a channel definition with the same name for each path to a given enclosure. vdev_id can replace the existing zpool_id script on systems where the storage topology conforms to sas_direct or sas_switch. The script could be extended to support other topologies as well. The advantage of vdev_id is that it is driven by a single static input file that can be shared across multiple nodes having a common storage toplogy. zpool_id, on the other hand, requires a unique /etc/zfs/zdev.conf per node and a separate slot-mapping file. However, zpool_id provides the flexibility of using any device names that show up in /dev/disk/by-path, so it may still be needed on some systems. vdev_id's functionality subsumes that of the sas_switch_id script, and it is unlikely that anyone is using it, so sas_switch_id is removed. Finally, /dev/disk/by-vdev is added to the list of directories that 'zpool import' will scan. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #713

Add .zfs control directory Add support for the .zfs control directory. This was accomplished by leveraging as much of the existing ZFS infrastructure as posible and updating it for Linux as required. The bulk of the core functionality is now all there with the following limitations. *) The .zfs/snapshot directory automount support requires a 2.6.37 or newer kernel. The exception is RHEL6.2 which has backported the d_automount patches. *) Creating/destroying/renaming snapshots with mkdir/rmdir/mv in the .zfs/snapshot directory works as expected. However, this functionality is only available to root until zfs delegations are finished. * mkdir - create a snapshot * rmdir - destroy a snapshot * mv - rename a snapshot The following issues are known defeciences, but we expect them to be addressed by future commits. *) Add automount support for kernels older the 2.6.37. This should be possible using follow_link() which is what Linux did before. *) Accessing the .zfs/snapshot directory via NFS is not yet possible. The majority of the ground work for this is complete. However, finishing this work will require resolving some lingering integration issues with the Linux NFS kernel server. *) The .zfs/shares directory exists but no futher smb functionality has yet been implemented.

Simplify BDI integration Update the code to use the bdi_setup_and_register() helper to simplify the bdi integration code. The updated code now just registers the bdi during mount and destroys it during unmount. The only complication is that for 2.6.32 - 2.6.33 kernels the helper wasn't available so in these cases the zfs code must provide it. Luckily the bdi_setup_and_register() function is trivial.

Add backing_device_info per-filesystem For a long time now the kernel has been moving away from using the pdflush daemon to write 'old' dirty pages to disk. The primary reason for this is because the pdflush daemon is single threaded and can be a limiting factor for performance. Since pdflush sequentially walks the dirty inode list for each super block any delay in processing can slow down dirty page writeback for all filesystems. The replacement for pdflush is called bdi (backing device info). The bdi system involves creating a per-filesystem control structure each with its own private sets of queues to manage writeback. The advantage is greater parallelism which improves performance and prevents a single filesystem from slowing writeback to the others. For a long time both systems co-existed in the kernel so it wasn't strictly required to implement the bdi scheme. However, as of Linux 2.6.36 kernels the pdflush functionality has been retired. Since ZFS already bypasses the page cache for most I/O this is only an issue for mmap(2) writes which must go through the page cache. Even then adding this missing support for newer kernels was overlooked because there are other mechanisms which can trigger writeback. However, there is one critical case where not implementing the bdi functionality can cause problems. If an application handles a page fault it can enter the balance_dirty_pages() callpath. This will result in the application hanging until the number of dirty pages in the system drops below the dirty ratio. Without a registered backing_device_info for the filesystem the dirty pages will not get written out. Thus the application will hang. As mentioned above this was less of an issue with older kernels because pdflush would eventually write out the dirty pages. This change adds a backing_device_info structure to the zfs_sb_t which is already allocated per-super block. It is then registered when the filesystem mounted and unregistered on unmount. It will not be registered for mounted snapshots which are read-only. This change will result in flush-<pool> thread being dynamically created and destroyed per-mounted filesystem for writeback.

Add support for DISCARD to ZVOLs. DISCARD (REQ_DISCARD, BLKDISCARD) is useful for thin provisioning. It allows ZVOL clients to discard (unmap, trim) block ranges from a ZVOL, thus optimizing disk space usage by allowing a ZVOL to shrink instead of just grow. We can't use zfs_space() or zfs_freesp() here, since these functions only work on regular files, not volumes. Fortunately we can use the low-level function dmu_free_long_range() which does exactly what we want. Currently the discard operation is not added to the log. That's not a big deal since losing discard requests cannot result in data corruption. It would however result in disk space usage higher than it should be. Thus adding log support to zvol_discard() is probably a good idea for a future improvement. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov>

Fix synchronicity for ZVOLs. zvol_write() assumes that the write request must be written to stable storage if rq_is_sync() is true. Unfortunately, this assumption is incorrect. Indeed, "sync" does *not* mean what we think it means in the context of the Linux block layer. This is well explained in linux/fs.h: WRITE: A normal async write. Device will be plugged. WRITE_SYNC: Synchronous write. Identical to WRITE, but passes down the hint that someone will be waiting on this IO shortly. WRITE_FLUSH: Like WRITE_SYNC but with preceding cache flush. WRITE_FUA: Like WRITE_SYNC but data is guaranteed to be on non-volatile media on completion. In other words, SYNC does not *mean* that the write must be on stable storage on completion. It just means that someone is waiting on us to complete the write request. Thus triggering a ZIL commit for each SYNC write request on a ZVOL is unnecessary and harmful for performance. To make matters worse, ZVOL users have no way to express that they actually want data to be written to stable storage, which means the ZIL is broken for ZVOLs. The request for stable storage is expressed by the FUA flag, so we must commit the ZIL after the write if the FUA flag is set. In addition, we must commit the ZIL before the write if the FLUSH flag is set. Also, we must inform the block layer that we actually support FLUSH and FUA.

Improve ZVOL queue behavior. The Linux block device queue subsystem exposes a number of configurable settings described in Linux block/blk-settings.c. The defaults for these settings are tuned for hard drives, and are not optimized for ZVOLs. Proper configuration of these options would allow upper layers (I/O scheduler) to take better decisions about write merging and ordering. Detailed rationale: - max_hw_sectors is set to unlimited (UINT_MAX). zvol_write() is able to handle writes of any size, so there's no reason to impose a limit. Let the upper layer decide. - max_segments and max_segment_size are set to unlimited. zvol_write() will copy the requests' contents into a dbuf anyway, so the number and size of the segments are irrelevant. Let the upper layer decide. - physical_block_size and io_opt are set to the ZVOL's block size. This has the potential to somewhat alleviate issue #361 for ZVOLs, by warning the upper layers that writes smaller than the volume's block size will be slow. - The NONROT flag is set to indicate this isn't a rotational device. Although the backing zpool might be composed of rotational devices, the resulting ZVOL often doesn't exhibit the same behavior due to the COW mechanisms used by ZFS. Setting this flag will prevent upper layers from making useless decisions (such as reordering writes) based on incorrect assumptions about the behavior of the ZVOL.

Move partition scanning from userspace to module. Currently, zpool online -e (dynamic vdev expansion) doesn't work on whole disks because we're invoking ioctl(BLKRRPART) from userspace while ZFS still has a partition open on the disk, which results in EBUSY. This patch moves the BLKRRPART invocation from the zpool utility to the module. Specifically, this is done just before opening the device in vdev_disk_open() which is called inside vdev_reopen(). This requires jumping through some hoops to get to the disk device from the partition device, and to make sure we can still open the partition after the BLKRRPART call. Note that this new code path is triggered on dynamic vdev expansion only; other actions, like creating a new pool, are unchanged and still call BLKRRPART from userspace. This change also depends on API changes which are available in 2.6.37 and latter kernels. The build system has been updated to detect this, but there is no compatibility mode for older kernels. This means that online expansion will NOT be available in older kernels. However, it will still be possible to expand the vdev offline.

Move partition scanning from userspace to module. Currently, zpool online -e (dynamic vdev expansion) doesn't work on whole disks because we're invoking ioctl(BLKRRPART) from userspace while ZFS still has a partition open on the disk, which results in EBUSY. This patch moves the BLKRRPART invocation from the zpool utility to the module. Specifically, this is done just before opening the device in vdev_disk_open() which is called inside vdev_reopen(). This requires jumping through some hoops to get to the disk device from the partition device, and to make sure we can still open the partition after the BLKRRPART call. Note that this new code path is triggered on dynamic vdev expansion only; other actions, like creating a new pool, are unchanged and still call BLKRRPART from userspace. This change also depends on API changes which are available in 2.6.37 and latter kernels. The build system has been updated to detect this, but there is no compatibility mode for older kernels. This means that online expansion will NOT be available in older kernels. However, it will still be possible to expand the vdev offline.

Linux compat 2.6.39: mount_nodev() The .get_sb callback has been replaced by a .mount callback in the file_system_type structure. When using the new interface the caller must now use the mount_nodev() helper. Unfortunately, the new interface no longer passes the vfsmount down to the zfs layers. This poses a problem for the existing implementation because we currently save this pointer in the super block for latter use. It provides our only entry point in to the namespace layer for manipulating certain mount options. This needed to be done originally to allow commands like 'zfs set atime=off tank' to work properly. It also allowed me to keep more of the original Solaris code unmodified. Under Solaris there is a 1-to-1 mapping between a mount point and a file system so this is a fairly natural thing to do. However, under Linux they many be multiple entries in the namespace which reference the same filesystem. Thus keeping a back reference from the filesystem to the namespace is complicated. Rather than introduce some ugly hack to get the vfsmount and continue as before. I'm leveraging this API change to update the ZFS code to do things in a more natural way for Linux. This has the upside that is resolves the compatibility issue for the long term and fixes several other minor bugs which have been reported. This commit updates the code to remove this vfsmount back reference entirely. All modifications to filesystem mount options are now passed in to the kernel via a '-o remount'. This is the expected Linux mechanism and allows the namespace to properly handle any options which apply to it before passing them on to the file system itself. Aside from fixing the compatibility issue, removing the vfsmount has had the benefit of simplifying the code. This change which fairly involved has turned out nicely.

Linux 3.1 compat, super_block->s_shrink The Linux 3.1 kernel has introduced the concept of per-filesystem shrinkers which are directly assoicated with a super block. Prior to this change there was one shared global shrinker. The zfs code relied on being able to call the global shrinker when the arc_meta_limit was exceeded. This would cause the VFS to drop references on a fraction of the dentries in the dcache. The ARC could then safely reclaim the memory used by these entries and honor the arc_meta_limit. Unfortunately, when per-filesystem shrinkers were added the old interfaces were made unavailable. This change adds support to use the new per-filesystem shrinker interface so we can continue to honor the arc_meta_limit. The major benefit of the new interface is that we can now target only the zfs filesystem for dentry and inode pruning. Thus we can minimize any impact on the caching of other filesystems. In the context of making this change several other important issues related to managing the ARC were addressed, they include: * The dnlc_reduce_cache() function which was called by the ARC to drop dentries for the Posix layer was replaced with a generic zfs_prune_t callback. The ZPL layer now registers a callback to drop these dentries removing a layering violation which dates back to the Solaris code. This callback can also be used by other ARC consumers such as Lustre. arc_add_prune_callback() arc_remove_prune_callback() * The arc_reduce_dnlc_percent module option has been changed to arc_meta_prune for clarity. The dnlc functions are specific to Solaris's VFS and have already been largely eliminated already. The replacement tunable now represents the number of bytes the prune callback will request when invoked. * Less aggressively invoke the prune callback. We used to call this whenever we exceeded the arc_meta_limit however that's not strictly correct since it results in over zeleous reclaim of dentries and inodes. It is now only called once the arc_meta_limit is exceeded and every effort has been made to evict other data from the ARC cache. * More promptly manage exceeding the arc_meta_limit. When reading meta data in to the cache if a buffer was unable to be recycled notify the arc_reclaim thread to invoke the required prune. * Added arcstat_prune kstat which is incremented when the ARC is forced to request that a consumer prune its cache. Remember this will only occur when the ARC has no other choice. If it can evict buffers safely without invoking the prune callback it will. * This change is also expected to resolve the unexpect collapses of the ARC cache. This would occur because when exceeded just the arc_meta_limit reclaim presure would be excerted on the arc_c value via arc_shrink(). This effectively shrunk the entire cache when really we just needed to reclaim meta data. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #466 Closes #292

Multipath device manageability improvements Update udev helper scripts to deal with device-mapper devices created by multipathd. These enhancements are targeted at a particular storage network topology under evaluation at LLNL consisting of two SAS switches providing redundant connectivity between multiple server nodes and disk enclosures. The key to making these systems manageable is to create shortnames for each disk that conveys its physical location in a drawer. In a direct-attached topology we infer a disk's enclosure from the PCI bus number and HBA port number in the by-path name provided by udev. In a switched topology, however, multiple drawers are accessed via a single HBA port. We therefore resort to assigning drawer identifiers based on which switch port a drive's enclosure is connected to. This information is available from sysfs. Add options to zpool_layout to generate an /etc/zfs/zdev.conf using symbolic links in /dev/disk/by-id of the form <label>-<UUID>-switch-port:<X>-slot:<Y>. <label> is a string that depends on the subsystem that created the link and defaults to "dm-uuid-mpath" (this prefix is used by multipathd). <UUID> is a unique identifier for the disk typically obtained from the scsi_id program, and <X> and <Y> denote the switch port and disk slot numbers, respectively. Add a callout script sas_switch_id for use by multipathd to help create symlinks of the form described above. Update zpool_id and the udev zpool rules file to handle both multipath devices and conventional drives.

Add make rule for building Arch Linux packages Added the necessary build infrastructure for building packages compatible with the Arch Linux distribution. As such, one can now run: $ ./configure $ make pkg # Alternatively, one can run 'make arch' as well on the Arch Linux machine to create two binary packages compatible with the pacman package manager, one for the zfs userland utilities and another for the zfs kernel modules. The new packages can then be installed by running: # pacman -U $package.pkg.tar.xz In addition, source-only packages suitable for an Arch Linux chroot environment or remote builder can also be build using the 'sarch' make rule. NOTE: Since the source dist tarball is created on the fly from the head of the build tree, it's MD5 hash signature will be continually influx. As a result, the md5sum variable was intentionally omitted from the PKGBUILD files, and the '--skipinteg' makepkg option is used.

Add vdev_id for JBOD-friendly udev aliases vdev_id parses the file /etc/zfs/vdev_id.conf to map a physical path in a storage topology to a channel name. The channel name is combined with a disk enclosure slot number to create an alias that reflects the physical location of the drive. This is particularly helpful when it comes to tasks like replacing failed drives. Slot numbers may also be re-mapped in case the default numbering is unsatisfactory. The drive aliases will be created as symbolic links in /dev/disk/by-vdev. The only currently supported topologies are sas_direct and sas_switch: o sas_direct - a channel is uniquely identified by a PCI slot and a HBA port o sas_switch - a channel is uniquely identified by a SAS switch port A multipath mode is supported in which dm-mpath devices are handled by examining the first running component disk, as reported by 'multipath -l'. In multipath mode the configuration file should contain a channel definition with the same name for each path to a given enclosure. vdev_id can replace the existing zpool_id script on systems where the storage topology conforms to sas_direct or sas_switch. The script could be extended to support other topologies as well. The advantage of vdev_id is that it is driven by a single static input file that can be shared across multiple nodes having a common storage toplogy. zpool_id, on the other hand, requires a unique /etc/zfs/zdev.conf per node and a separate slot-mapping file. However, zpool_id provides the flexibility of using any device names that show up in /dev/disk/by-path, so it may still be needed on some systems. vdev_id's functionality subsumes that of the sas_switch_id script, and it is unlikely that anyone is using it, so sas_switch_id is removed. Finally, /dev/disk/by-vdev is added to the list of directories that 'zpool import' will scan. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #713

The advantage of vdev_id is that it is driven by a single static input file that can be shared across multiple nodes having a common storage toplogy. zpool_id, on the other hand, requires a unique /etc/zfs/zdev.conf per node and a separate slot-mapping file. However, zpool_id provides the flexibility of using any device names that show up in /dev/disk/by-path, so it may still be needed on some systems. vdev_id's functionality subsumes that of the sas_switch_id script, and it is unlikely that anyone is using it, so sas_switch_id is removed.

Multipath device manageability improvements Update udev helper scripts to deal with device-mapper devices created by multipathd. These enhancements are targeted at a particular storage network topology under evaluation at LLNL consisting of two SAS switches providing redundant connectivity between multiple server nodes and disk enclosures. The key to making these systems manageable is to create shortnames for each disk that conveys its physical location in a drawer. In a direct-attached topology we infer a disk's enclosure from the PCI bus number and HBA port number in the by-path name provided by udev. In a switched topology, however, multiple drawers are accessed via a single HBA port. We therefore resort to assigning drawer identifiers based on which switch port a drive's enclosure is connected to. This information is available from sysfs. Add options to zpool_layout to generate an /etc/zfs/zdev.conf using symbolic links in /dev/disk/by-id of the form <label>-<UUID>-switch-port:<X>-slot:<Y>. <label> is a string that depends on the subsystem that created the link and defaults to "dm-uuid-mpath" (this prefix is used by multipathd). <UUID> is a unique identifier for the disk typically obtained from the scsi_id program, and <X> and <Y> denote the switch port and disk slot numbers, respectively. Add a callout script sas_switch_id for use by multipathd to help create symlinks of the form described above. Update zpool_id and the udev zpool rules file to handle both multipath devices and conventional drives.

Add vdev_id for JBOD-friendly udev aliases vdev_id parses the file /etc/zfs/vdev_id.conf to map a physical path in a storage topology to a channel name. The channel name is combined with a disk enclosure slot number to create an alias that reflects the physical location of the drive. This is particularly helpful when it comes to tasks like replacing failed drives. Slot numbers may also be re-mapped in case the default numbering is unsatisfactory. The drive aliases will be created as symbolic links in /dev/disk/by-vdev. The only currently supported topologies are sas_direct and sas_switch: o sas_direct - a channel is uniquely identified by a PCI slot and a HBA port o sas_switch - a channel is uniquely identified by a SAS switch port A multipath mode is supported in which dm-mpath devices are handled by examining the first running component disk, as reported by 'multipath -l'. In multipath mode the configuration file should contain a channel definition with the same name for each path to a given enclosure. vdev_id can replace the existing zpool_id script on systems where the storage topology conforms to sas_direct or sas_switch. The script could be extended to support other topologies as well. The advantage of vdev_id is that it is driven by a single static input file that can be shared across multiple nodes having a common storage toplogy. zpool_id, on the other hand, requires a unique /etc/zfs/zdev.conf per node and a separate slot-mapping file.

Finally, /dev/disk/by-vdev is added to the list of directories that 'zpool import' will scan. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #713

Multipath device manageability improvements Update udev helper scripts to deal with device-mapper devices created by multipathd. These enhancements are targeted at a particular storage network topology under evaluation at LLNL consisting of two SAS switches providing redundant connectivity between multiple server nodes and disk enclosures. The key to making these systems manageable is to create shortnames for each disk that conveys its physical location in a drawer. In a direct-attached topology we infer a disk's enclosure from the PCI bus number and HBA port number in the by-path name provided by udev. In a switched topology, however, multiple drawers are accessed via a single HBA port. We therefore resort to assigning drawer identifiers based on which switch port a drive's enclosure is connected to. This information is available from sysfs. Add options to zpool_layout to generate an /etc/zfs/zdev.conf using symbolic links in /dev/disk/by-id of the form <label>-<UUID>-switch-port:<X>-slot:<Y>. <label> is a string that depends on the subsystem that created the link and defaults to "dm-uuid-mpath" (this prefix is used by multipathd). <UUID> is a unique identifier for the disk typically obtained from the scsi_id program, and <X> and <Y> denote the switch port and disk slot numbers, respectively. Add a callout script sas_switch_id for use by multipathd to help create symlinks of the form described above. Update zpool_id and the udev zpool rules file to handle both multipath devices and conventional drives.

Add vdev_id for JBOD-friendly udev aliases vdev_id parses the file /etc/zfs/vdev_id.conf to map a physical path in a storage topology to a channel name. The channel name is combined with a disk enclosure slot number to create an alias that reflects the physical location of the drive. This is particularly helpful when it comes to tasks like replacing failed drives. Slot numbers may also be re-mapped in case the default numbering is unsatisfactory. The drive aliases will be created as symbolic links in /dev/disk/by-vdev. The only currently supported topologies are sas_direct and sas_switch: o sas_direct - a channel is uniquely identified by a PCI slot and a HBA port o sas_switch - a channel is uniquely identified by a SAS switch port A multipath mode is supported in which dm-mpath devices are handled by examining the first running component disk, as reported by 'multipath -l'. In multipath mode the configuration file should contain a channel definition with the same name for each path to a given enclosure. vdev_id can replace the existing zpool_id script on systems where the storage topology conforms to sas_direct or sas_switch. The script could be extended to support other topologies as well. The advantage of vdev_id is that it is driven by a single static input file that can be shared across multiple nodes having a common storage toplogy. zpool_id, on the other hand, requires a unique /etc/zfs/zdev.conf per node and a separate slot-mapping file.
