Hi

responding to myself here..

I ran zpool scrub on it.

It started to resilver ; but then I got:

Problems with ZFS:   pool: pool
state: DEGRADED
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:

        <metadata>:<0x2013>
        <metadata>:<0x2014>

Any pointers on what I should do now?

All my data seems fine :(
