Add build system Add autoconf style build infrastructure to the ZFS tree. This includes autogen.sh, configure.ac, m4 macros, some scripts/*, and makefiles for all the core ZFS components. 2010-08-26 18:22:58 +00:00			`#`
Move udev rules from /etc/udev to /lib/udev This change moves the default install location for the zfs udev rules from /etc/udev/ to /lib/udev/. The correct convention is for rules provided by a package to be installed in /lib/udev/. The /etc/udev/ directory is reserved for custom rules or local overrides. Additionally, this patch cleans up some abuse of the bindir install location by adding a udevdir and udevruledir install directories. This allows us to revert to the default bin install location. The udev install directories can be set with the following new options. --with-udevdir=DIR install udev helpers [EPREFIX/lib/udev] --with-udevruledir=DIR install udev rules [UDEVDIR/rules.d] Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #356 2011-08-05 19:22:58 +00:00			`# /lib/udev/rules.d/60-zpool.rules`

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. 2011-06-21 23:18:27 +00:00			`KERNEL=="[0-9]", ENV{SUBSYSTEM}=="block", ENV{DEVTYPE}=="partition", ENV{ID_ZPOOL}=="?", SYMLINK+="$env{ID_ZPOOL_PATH}-part%n"`
