It depends on which RAID level and which disk fail. In this case (RAID5),
you're going to have to rebuild both parity *AND* data (this isn't RAID
[2-4]...) While the fsck should see the same information whether or not
a resync needs to occur, it's going to be *much* slower to fsck during
a resync than after the resync is completed. (not to mention that the
fsck will have to recreate the data to check -- hopefully the rebuild
process will use this so it doesn't have to recreate the data twice.)
