When I reboot my machine, fmstat always shows 12 counts for zfs-* categories. fmdump and fmdump -e don't report anything and I don't see anything in the logs of the current or previous BE (when applicable). I'm at a bit of a loss to figure out what happened. Two of the drives are on the inte

2012-06-01 Thread Richard L. Hamilton
In a non-COW filesystem, one would expect that rewriting an already allocated block would never fail for out-of-space (ENOSPC). But I would expect that it could on ZFS - definitely if there was a snapshot around, as it would create a divergence from that snapshot (because both blocks would be k
