See my other on list mail about the fallacy of the idea that consistency
of garbage data blocks is any better than inconsistency. As I mentioned
in it, even if it's a deleted file, a lost metadata block, etc., it will
always be consistent if it's a valid block to consider during rebuild
because *at some point in time* since the filesystem was created, it
will have been written. Reiserfsck is just as susceptible to random
garbage on a single disk not part of any raid array as it is to
inconsistent blocks in a raid1 as it is to a fully synced raid1 array
with garbage that looks like a reiserfs. That's a shortcoming of that
filesystem and there is no one to blame but Hans Reiser for that.
