[Dark26]

Bonjour,

Fisrt of all , it's fresh home lab, so no vm; no critical data.


before :

root@qc5000:~# zpool status -v
  pool: rpool

errors: No known data errors

But i tried to do a backup to PBS:cool: of the Promox fresh install, and the problem appears during the process.

root@qc5000:~# zpool status -v
pool: rpool
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.

[/CODE]

"zpool scrub rpool "don't do anything; the error keep coming.

is there a way to delete the directory ?

root@qc5000:/tmp# cd tr
root@qc5000:/tmp/tr# ls
ls: reading directory '.': Input/output error

Thanks dark26

Try clearing the errors via "zpool clear" and issue a scrub again. If that does not work the only thing ist to delete the dataset.

zfs is the command you should explore (don't know the syntax of the top of my head)

ZFS noticed an unrecoverable error in the storage of the directory, which will not go away until you either overwrite the place of the error, or delete, the directory or file that contains the error (and run a scrub afterwards). For files, this usually means overwriting them with a copy from a backup. With directories, I don't know any other way than deleting the entire directory tree (and copy the contents from a backup).
