With a RAID-Z1 pool this can be a life / pool saver, in case a bad block is found on another disk, but the failing disk has that block stripe still functional.Īiming to mostly replicate the build from (with some mods, hopefully around about as good as that link) This allows ZFS to keep the existing failing disk as a source of data, in addition to the other disks. When replacing a failing but not failed disk, if you have a spare disk slot, do a replace in place. That said, hardware problems have had an impact on graceless reboots, causing data or pool loss. And do so without data loss, (except any data in flight, like any other file system). ZFS was specifically designed to survive a graceless, (aka a crash or hard power off), reboot. Please supply the output of the following command, in CODE tags That would either be file loss or pool loss, depending on what we see. But, it could be you lost blocks or another whole disk in your RAID-Z1. ZFS will normally resume the disk replacement on reboot. This is likely due to your in-complete disk replacement.
