说明
zed (ZFS Event Daemon) monitors ZFS kernel events and executes scripts in response. It listens for events like scrub completion, device failures, pool imports, and data errors, then runs corresponding handler scripts. Scripts are stored in /etc/zfs/zed.d/ with naming convention event-name.sh. Enabled scripts are symlinked to be active. Common events include: - resilver.finish - Resilver completed - scrub.finish - Scrub completed - statechange - Pool state changed - data - Data errors detected zed enables automated responses to ZFS events like sending email notifications on errors or running custom maintenance scripts.
