** Description changed:
- 3)
- After a reboot, ZFS pool never stopped trying to import the pool. It was
blocking the boot-sequence and I had to rename the /etc/zfs/zpool.cache to
another name, in order to boot the system.
- There was an upgrade made before reboot, but that was not anything with zfs.
-
-
- The problem is that zpool datastore is not possible to import in normal way.
Only in readonly=on is I able to import it.
- Also the Scub seems to be active on the readonly, but it will never stops
since it not possible to write to the pool.
- I cannot stop scrub either since I can only import it at readonly.
-
-
- If I import it at readonly it works and I can access the files. But if import
normally a panic occur, and the process hangs.
-
- 4)
- Expected to be able to import the zpool as normal.
