Hi,
I have lost a ZFS volume and I am hoping to get some help to recover the
information ( a couple of months worth of work :( ).
I have been using ZFS for more than 6 months on this project. Yesterday
I ran a "zvol status" command, the system froze and rebooted. When it
came back the discs where not available.
See bellow the output of " zpool status", "format" and "zdb".
Do you think there is something that can be done to recover lost data?
Thanks,
Vic
