Hey,

 

today my server stopped working. 

Error is: 

PANIC: cache: blkptr at 000000009b7d17f2 has invalid COMPRESS 24

 

After a reboot the error stay and I seen that it happend when the cache get's mounted.

i tried a zpool status cache -v.

  pool: cache

        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:

        cache:/system/docker/docker.img

 

could be the demage on the docker.img be the source for the mount error?

How can I delete the docker.img from the pool without mount?

See if it mounts read only, and if yes backup and re-format:

 

zpool import -o readonly=on cache
