Mounting from zfs:zroot/ROOT/default failed with error 6. Trying to recover from a livecd was not helping. I could import the pool, b= ut not remove the device. Trying to offline the device would return a different error --=20 cannot offline 16642195929625272860: log device has unplayed intent logs I ended up building a custom zfs.ko with the attached patch which I derived from this ZoL Github issue: https://github.com/zfsonlinux/zfs/issues/4270 This allowed me to make the pool usable again. After a scrub things are mos= tly OK now, though I have one mysterious error left; the other errors it report= ed are now gone. root@colo:/usr/src # zpool status -v pool: zroot state: ONLINE status: One or more devices has experienced an error resulting in data corruption. Applications may be affected. action: Restore the file in question if possible. Otherwise restore the entire pool from backup. see: http://illumos.org/msg/ZFS-8000-8A scan: scrub repaired 0 in 0 days 20:14:51 with 0 errors on Fri Jun 7 15:58:42 2019 config: NAME STATE READ WRITE CKSUM zroot ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 da4p3.eli ONLINE 0 0 0 da5p3.eli ONLINE 0 0 0 mirror-1 ONLINE 0 0 0 da0p3.eli ONLINE 0 0 0 da2p3.eli ONLINE 0 0 0 mirror-2 ONLINE 0 0 0 da1p3.eli ONLINE 0 0 0 da3p3.eli ONLINE 0 0 0 errors: Permanent errors have been detected in the following files: <0x31abf>:<0x0> --=20 You are receiving this mail because: You are the assignee for the bug.=
