March 23 - ZFS Error#
I got a ZFS error. Documenting it here:
root@bigger-fish:~# zpool status -v manta
pool: manta
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.

errors: Permanent errors have been detected in the following files:
/manta/subvol-100-disk-0/media/public/movies/The Darkest Minds (2018)/The.Darkest.Minds.2018.1080p.BluRay.x264-[YTS.AM].mp4
After deleting the file, it is replaced with manta/subvol-100-disk-0:<0x1ea>.
Now I run a zpool scrub manta.
The command completes, but the scrub is still in progress.
I can see the progress by running zpool status -v manta.
After a while:
root@bigger-fish:~# zpool status -v manta
pool: manta
state: ONLINE
status: Some supported and requested features are not enabled on the pool.
The pool can still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
the pool may no longer be accessible by software that does not support
the features. See zpool-features(7) for details.
