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).

# Log the zevent via syslog.
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>

Enclosure LED fixes - Pass $VDEV_ENC_SYSFS_PATH to 'zpool [iostat|status] -c' to include enclosure LED sysfs path. - Set LEDs correctly after import. This includes clearing any erroniously set LEDs prior to the import, and setting the LED for any UNAVAIL drives. - Include symlink for vdev_attach-led.sh in Makefile.am. - Print the VDEV path in all-syslog.sh, and fix it so the pool GUID actually prints.

Bring over illumos ZFS FMA logic -- phase 1 This first phase brings over the ZFS SLM module, zfs_mod.c, to handle auto operations in response to disk events. Disk event monitoring is provided from libudev and generates the expected payload schema for zfs_mod. This work leverages the recently added devid and phys_path strings in the vdev label.
