Hello everyone!

After upgrading my zfs-only system from 8.2 to 9.1 I have many errors
related to zfs in my /var/log/messages:

errors: Permanent errors have been detected in the following files:

        zmirror/usr:<0x0>
        <0xc8>:<0x0>

zfs clear and zfs scrub didn't help me, so I have created a new
filesystem zmirror/usr2 with mountpoint=/usr and copy all files manually
from zmirror/usr to zmirror/usr2 because zfs send failed with i/o error.
The system whith new /usr boots fine and now I try to remove broken
zmirror/usr, but still no luck:

root at gw:/ # zfs destroy zmirror/usr
internal error: Unknown error: 122
Аварийное завершение(core dumped)

How can I solve this issue?
