Now I have a few problems:
1) The old ad4 is still listed, even after several scrub/resilvers.
Shouldn't it go away?
2) Although I lost a whole directory with ~1TB of music, the space
allocated to that directory is still around according df.
3) I have another bunch of files that appear in directory listings, but
if I get "Illegal byte sequence" errors when trying to read them (with
anything - du, file, wc).
I have backups of most of the stuff on the pool (although it'd be nice
to recover the more recent data), but how do I get out of this situation
without nuking the site from orbit? (my current plan) Firstly, to get a
reliable representation of what's actually on the filesystem, and for
bonus points, getting back some of the data that should be intact (only
one disk in the set was actually bad, right?).
--As for the rest, it is mine.
This page seems relevant:
<http://dlc.sun.com/osol/docs/content/ZFSADMIN/gbbwl.html>
It looks like some damaged data made it through the normal ZFS integrity
checks. There are some instructions on the link on how to identify the
files/blocks in question. If it's just files, then it looks like you
should be able to delete them, restore from backup, and go. (With the rest
of your pool working just fine.) If it's data blocks, well, you probably
wouldn't be in as good as state as you are. ;)
That said, from the output you listed, there are probably 15,190 or so
files with errors...
