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).

zed needs libzfs_core As of a recent group of Illumos/Delphix updates, zed needs libzfs_core in order to resolve lzc_get_bookmarks() and likely other functions going forward. Signed-off-by: Tim Chase <tim@chase2k.com> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #2534

Add automatic hot spare functionality When a vdev starts getting I/O or checksum errors it is now possible to automatically rebuild to a hot spare device. To cleanly support this functionality in a shell script some additional information was added to all zevent ereports which include a vdev. This covers both io and checksum zevents but may be used but other scripts. In the Illumos FMA solution the same information is required but it is retrieved through the libzfs library interface. Specifically the following members were added: vdev_spare_paths - List of vdev paths for all hot spares. vdev_spare_guids - List of vdev guids for all hot spares. vdev_read_errors - Read errors for the problematic vdev vdev_write_errors - Write errors for the problematic vdev vdev_cksum_errors - Checksum errors for the problematic vdev. By default the required hot spare scripts are installed but this functionality is disabled. To enable hot sparing uncomment the ZED_SPARE_ON_IO_ERRORS and ZED_SPARE_ON_CHECKSUM_ERRORS in the /etc/zfs/zed.d/zed.rc configuration file. These scripts do no add support for the autoexpand property. At a minimum this requires adding a new udev rule to detect when a new device is added to the system. It also requires that the autoexpand policy be ported from Illumos, see: https://github.com/illumos/illumos-gate/blob/master/usr/src/cmd/syseventd/modules/zfs_mod/zfs_mod.c Support for detecting the correct name of a vdev when it's not a whole disk was added by Turbo Fredriksson.
