Hi--
The best approach is to correct the issues that are causing these
problems in the first place. The fmdump -eV commnand will identify
the hardware problems that caused the checksum errors and the corrupted
files.
You might be able to use some combination of zpool scrub, zpool clear,
and removing these corrupted files manually, but unless the failing
disks (?) are repaired, you could potentially lose more data.
We have zpool recovery feature in build 128 but it will not work
in this scenario since the pool is online (its importable).
If you can't repair the underlying hardware issues and you have no
backup of this data, then you might consider reviewing the steps
that are described here:

We haven't had a chance to look at this script closely or test it yet so
the usual caveats apply.
Thanks,
Cindy

Hello !
Can anybody help me with some trouble:
j...@opensolaris:~# zpool status -v
pool: green
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.

As you can see in output my zfs pool have permanent errors with some files and
directories - but how i can clear these errors? I try to do scrub one time, and
bigger part of errors gone, but some stay, and i can't delete it :
j...@opensolaris:~# rm -rf /green/home/epiq/mus/easy
rm: Unable to remove directory /green/home/epiq/mus/easy: Directory not empty
j...@opensolaris:~# rmdir --ignore-fail-on-non-empty /green/home/epiq/mus/easy
rmdir: illegal option -- ignore-fail-on-non-empty

j...@opensolaris:~# rm -rf

j...@opensolaris:~# ls -la

While i googled around this problem i found zdb commands:
