Error when backing up files..

[Plato]

Hi,

Recently two of my disks started acting up on my raidz1 array so I created a new raidz2 array from new disks..

But while migrating via zfs send/receive commands I got this error:

Code:

errors: Permanent errors have been detected in the following files:

		media@migrate:<0x20>

Also one of my disks gave too many errors and now my media pool is degraded..

Migration is still going on, but what would this error cause at the end of migration? An error in a file or something else.

BTW, the task output is like this:

Code:

19:02:08	534G   media@migrate
19:02:09	535G   media@migrate
19:02:10	535G   media@migrate
19:02:11	535G   media@migrate
19:02:12	536G   media@migrate
19:02:13	536G   media@migrate
19:02:14	536G   media@migrate
19:02:15	537G   media@migrate
.

Looks like metadata corruption. Is that on the old pool?

Hmm, yeah it was on the old pool. Well, it seems it's gone haywire. I can still recover some files but not with send/receive it seems, because it halts somewhere along the way. I'll copy as much as I can and then restore rest from an online backup.

Yes, send/recv is going to be particularly vulnerable to the metadata corruption. Transferring files may work better.
