Seems to be only associated with the filesystem, rather than the pool. Well, my "tank" pool, (the raidz) shows zpool scrub making 0 fixes but there being unrecoverable erorrs in tank/home:<0x0>, but my backup file system (the one I send snapshot deltas to) shows exactly the same errors with no tank problems. (Hmm. Hold that thought: I haven't actually tried a scrub on the backup file system. It's just zpool status that shows no errors. Running a scrub now. Will take a while: it's a fairly slow USB2-connected disk. Zpool status says expect 10+ hours...)
Just want to update this: zpool scrub on the bkp2pool finished with zero errors
found, but the
filesystem corruption noticed in the main pool (tank/home) has been faithfully
reproduced.
That is: I have a directory Maildir.bad that echo .* shows:
Maildir.bad/. Maildir.bad/.. Maildir.bad/.AppleDouble
Maildir.bad/.Suppliers.2010 Maildir.bad/.Unix
But the .Suppliers.2010 entry does not seem to have an inode number (let alone
an inode):
$ ls -ai Maildir.bad returns:
ls: .Suppliers.2010: No such file or directory
7906 .
7810 ..
82016 .AppleDouble
80774 .Unix
Is this not terminally weird? Is there any way to de-confuse ZFS?
Since memtest86+ did not seem to boot properly on this system, I've ordered new
memory (twice as
much: will be 8G now.) Also ordered a UPS. We'll see if that helps with
anything.
Cheers,
