OK this is driving me nuts. Running zfs on a system, and my root partition has been shrinking with seeming no explanation. I have now run out of space and can't find where it all went.

A simple df shows the following (You can ignore the TV filesystems, i'm only concerned with the root):

[root@SV02 /]# df -h

Used/available don't seem consistent...

Trying to track it down:

[root@SV02 /]# du -sh *
 0K bin

 10M core
 2.0M dev
 430K devices
 58M etc
 405M export

 10M root
 23K rpool

 12K tmp
 1.5G usr
 3.1G var

OK nothing there... Thought maybe a snapshot, but that doesn't seem to be the case:

34 gigs available but where, I do not know? At a loss and unfortunately I don't quite have a good enough grasp of zfs to properly troubleshoot. It's persistent after reboots and I haven't deleted any large files or anything recently, so don't think it's a process holding on to anything... Save me, you're my only hope!
