I've been using a ZFS volume exported via iscsi as a Time Machine drive
for my Mac Book. After a reboot last night (after installing an SSD as
ZIL for a pool), the Mac can't see the volume. I think some combination
of the iscsi target shutdown and the Mac's backup behavior has left the
volume in a bad state (from the Mac file system point of view.)
The Mac can mount newly created iscsi volumes, but the problem appears
to be that the Mac can't fsck the ZFS volume over iscsi (at least, it
doesn't appear from the logs that it's trying to.)
I'd really like to not lose that backup data, so I'm wondering:
1) What's the best way to get that volume out onto an external drive
that I can plug into the Mac? Just dd the /dev/zvol out to the external
drive?
2) How do I re-import the volume once fsck has worked?
I guess the other alternative is to clone one of the volume's snapshots
from a time the backup was working and then see if that can be mounted.
Any advice would be greatly appreciated.
Steve
