Initial implementation of zed (ZFS Event Daemon) zed monitors ZFS events. When a zevent is posted, zed will run any scripts that have been enabled for the corresponding zevent class. Multiple scripts may be invoked for a given zevent. The zevent nvpairs are passed to the scripts as environment variables. Events are processed synchronously by the single thread, and there is no maximum timeout for script execution. Consequently, a misbehaving script can delay (or forever block) the processing of subsequent zevents. Plans are to address this in future commits. Initial scripts have been developed to log events to syslog and send email in response to checksum/data/io errors and resilver.finish/scrub.finish events. By default, email will only be sent if the ZED_EMAIL variable is configured in zed.rc (which is serving as a config file of sorts until a proper configuration file is implemented).

systemd mount generator and tracking ZEDLET zfs-mount-generator implements the "systemd generator" protocol, producing systemd.mount units from the cached outputs of zfs list, during early boot, integrating with systemd. Each pool has an indpendent cache of the command zfs list -H -oname,mountpoint,canmount -tfilesystem -r $pool which is kept synchronized by the ZEDLET history_event-zfs-list-cacher.sh Datasets not in the cache will be loaded later in the boot process by zfs-mount.service, including pools without a cache. Among other things, this allows for complex mount hierarchies.

Cleanup ZEDLETs This commit factors out several common ZEDLET code blocks into zed-functions.sh. This shortens the length of the scripts, thereby (hopefully) making them easier to understand and maintain. In addition, this commit revamps the coding style used by the scripts to be more consistent and (again, hopefully) maintainable. It now mostly follows the Google Shell Style Guide. I've tried to assimilate the following resources: Google Shell Style Guide https://google-styleguide.googlecode.com/svn/trunk/shell.xml Dash as /bin/sh https://wiki.ubuntu.com/DashAsBinSh Filenames and Pathnames in Shell: How to do it Correctly http://www.dwheeler.com/essays/filenames-in-shell.html Common shell script mistakes http://www.pixelbeat.org/programming/shell_script_mistakes.html Finally, this commit updates the exit codes used by the ZEDLETs to be more consistent with one another. All scripts run cleanly through ShellCheck <http://www.shellcheck.net/>. All scripts have been tested on bash and dash. Signed-off-by: Chris Dunlap <cdunlap@llnl.gov>

Add illumos FMD ZFS logic to ZED -- phase 2 The phase 2 work primarily entails the Diagnosis Engine and the Retire Agent modules. It also includes infrastructure to support a crude FMD environment to host these modules. The Diagnosis Engine consumes I/O and checksum ereports and feeds them into a SERD engine which will generate a corres- ponding fault diagnosis when the SERD engine fires. All the diagnosis state data is collected into cases, one case per vdev being tracked. The Retire Agent responds to diagnosed faults by isolating the faulty VDEV. It will notify the ZFS kernel module of the new VDEV state (degraded or faulted). This agent is also responsible for managing hot spares across pools. When it encounters a device fault or a device removal it replaces the device with an appropriate spare if available.

Add libtpool (thread pools) OpenZFS provides a library called tpool which implements thread pools for user space applications. Porting this library means the zpool utility no longer needs to borrow the kernel mutex and taskq interfaces from libzpool. This code was updated to use the tpool library which behaves in a very similar fashion. Porting libtpool was relatively straight forward and minimal modifications were needed. The core changes were: * Fully convert the library to use pthreads. * Updated signal handling. * lmalloc/lfree converted to calloc/free * Implemented portable pthread_attr_clone() function. Finally, update the build system such that libzpool.so is no longer linked in to zfs(8), zpool(8), etc. All that is required is libzfs to which the zcommon soures were added (which is the way it always should have been). Removing the libzpool dependency resulted in several build issues which needed to be resolved. * Moved zfeature support to module/zcommon/zfeature_common.c * Moved ratelimiting to to module/zfs/zfs_ratelimit.c * Moved get_system_hostid() to lib/libspl/gethostid.c * Removed use of cmn_err() in zcommon source * Removed dprintf_setup() call from zpool_main.c and zfs_main.c * Removed highbit() and lowbit() * Removed unnecessary library dependencies from Makefiles * Removed fletcher-4 kstat in user space * Added sha2 support explicitly to libzfs * Added highbit64() and lowbit64() to zpool_util.c Reviewed-by: Tony Hutter <hutter2@llnl.gov> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #6442

Initial implementation of zed (ZFS Event Daemon) zed monitors ZFS events. When a zevent is posted, zed will run any scripts that have been enabled for the corresponding zevent class. Multiple scripts may be invoked for a given zevent. The zevent nvpairs are passed to the scripts as environment variables. Events are processed synchronously by the single thread, and there is no maximum timeout for script execution. Consequently, a misbehaving script can delay (or forever block) the processing of subsequent zevents. Plans are to address this in future commits. Initial scripts have been developed to log events to syslog and send email in response to checksum/data/io errors and resilver.finish/scrub.finish events. By default, email will only be sent if the ZED_EMAIL variable is configured in zed.rc (which is serving as a config file of sorts until a proper configuration file is implemented).

systemd mount generator and tracking ZEDLET zfs-mount-generator implements the "systemd generator" protocol, producing systemd.mount units from the cached outputs of zfs list, during early boot, integrating with systemd. Each pool has an indpendent cache of the command zfs list -H -oname,mountpoint,canmount -tfilesystem -r $pool which is kept synchronized by the ZEDLET history_event-zfs-list-cacher.sh Datasets not in the cache will be loaded later in the boot process by zfs-mount.service, including pools without a cache. Among other things, this allows for complex mount hierarchies.

Replace "email" ZEDLETs with "notify" ZEDLETs Several ZEDLETs already exist for sending email in reponse to a particular zevent. While email is ubiquitous, alternative methods may be better suited for some configurations. Instead of duplicating the "email" ZEDLETs for every future notification method, it is preferable to abstract the notification method into a function. This has the added benefit of reducing the amount of code duplicated between ZEDLETs, and allowing related bugs to be fixed in a single location. This commit replaces the existing "email" ZEDLETs with corresponding "notify" ZEDLETs. In addition, the ZEDLET code for sending an email message has been moved into the zed_notify_email() function. And this zed_notify_email() has been added to a generic zed_notify() function for sending notifications via all available methods that have been configured. This commit also changes a couple of related zed.rc variables. ZED_EMAIL_INTERVAL_SECS is changed to ZED_NOTIFY_INTERVAL_SECS, and ZED_EMAIL_VERBOSE is changed to ZED_NOTIFY_VERBOSE. Note that ZED_EMAIL remains unchanged as its use is solely for the email notification method. Signed-off-by: Chris Dunlap <cdunlap@llnl.gov>

Events which would be logged as sysevents on illumos have been been mapped to the 'sysevent' class for Linux. In addition, several subclass names have been changed to match what is used in OpenZFS. In all cases this means a '.' was changed to an '_' in the subclass. The scripts provided by ZoL have been updated, however users which provide scripts for any of the following events will need to rename them based on the new subclass names. ereport.fs.zfs.config.sync sysevent.fs.zfs.config_sync ereport.fs.zfs.zpool.destroy sysevent.fs.zfs.pool_destroy ereport.fs.zfs.zpool.reguid sysevent.fs.zfs.pool_reguid ereport.fs.zfs.vdev.remove sysevent.fs.zfs.vdev_remove ereport.fs.zfs.vdev.clear sysevent.fs.zfs.vdev_clear ereport.fs.zfs.vdev.check sysevent.fs.zfs.vdev_check ereport.fs.zfs.vdev.spare sysevent.fs.zfs.vdev_spare ereport.fs.zfs.vdev.autoexpand sysevent.fs.zfs.vdev_autoexpand ereport.fs.zfs.resilver.start sysevent.fs.zfs.resilver_start ereport.fs.zfs.resilver.finish sysevent.fs.zfs.resilver_finish ereport.fs.zfs.scrub.start sysevent.fs.zfs.scrub_start ereport.fs.zfs.scrub.finish sysevent.fs.zfs.scrub_finish ereport.fs.zfs.bootfs.vdev.attach sysevent.fs.zfs.bootfs_vdev_attach
