I tried to remove > the files in the snapshot directory, but it is read-only. This looks like pointers to files that were already deleted/purged. I once faced this errors but that was on bad controller, I don't think this can be caused by bad memory/errors. When that happened I scrubbed pool, removed all files noted, cleaned zpool errors (they are persistent, even the file was removed and snapshots doen't exist they are still shown) and scrubbed the pool again. > > Ideas? > > Linda > > > pool: pool > state: ONLINE > status: One or more devices is currently being resilvered.
