"My" FreeBSD system somehow rebooted itself last friday in the early
hours in the morning, and since then /var/log/messages is full with
messages like these:

i.e. errors op all disks that make up the pool. There appear to be more
than just the two offsets as mentioned in this block of messages but
so far it seems the number of them is limited.
Seemingly they stopped around the time I logged in.
I started a scrub, just in case. zpool status -v says this:
fourquid.1:~$ sudo zpool status -v
pool: tank
state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.
see: http://www.sun.com/msg/ZFS-8000-8A
scrub: scrub in progress for 0h23m, 4.70% done, 7h49m to go
config:
NAME STATE READ WRITE CKSUM
tank ONLINE 0 0 6.15K
raidz2 ONLINE 0 0 24.5K
da0 ONLINE 0 0 0
da1 ONLINE 0 0 0
da2 ONLINE 0 0 0
da3 ONLINE 0 0 0
da4 ONLINE 0 0 0
da5 ONLINE 0 0 0
errors: Permanent errors have been detected in the following files:
tank/vol-fourquid-1:<0x0>
tank/vol-fourquid-1:<0xc8190da>
How do I identify which files it is listing here?
