Moving ZFS

K

My file server using ZFS crashed due to hardware failure.

I've replaced the motherboard. The 8 disk backing the ZFS system were on a card which I transferred, so they're read in the same way.

I used
Code: 
zfs import box
to load the file system. box being the name of the fs. Is this correct?

When I do
Code: 
zfs list box
, I just get:
Code: 
NAME   USED  AVAIL  REFER MOUNTPOINT
box   5.75T  1.40T    10K legacy

It seems to me that the data is still there, but I'm not sure how to mount it. I don't want to experiment with it as there's lots of data to loose. Can anyone advise?

Thanks.
 
What's the output of zfs list (without the word box, so that it lists all the ZFS datasets).

If everything shows correctly there, then it's just a matter of setting mountpoints. At the very least, you'll need to set the mountpoint for the root dataset (box).

Thanks guys, I think I was experiencing sheer panic. I've been thru this before in my testing before moving to ZFS.

zfs list showed all the correct stuff, so I switched ZFS on in the rc.conf and rebooted and it came up mounted correctly.
Code: 
NAME         USED  AVAIL  REFER  MOUNTPOINT
box         5.75T  1.40T    10K  legacy
box/FreeBSD  294G  1.40T   294G  /mirror/FreeBSD
box/Linux    336G  1.40T   336G  /mirror/Linux
box/archive 59.0G  1.40T  59.0G  /archive
box/data     578G  1.40T   578G  /data
box/mmedia  4.52T  1.40T  4.52T  /export/mmedia

Thanks again, when I wasn't sure what was going on, I just switched the machine off, so not to make anything worse.
