I created a 1TB file on my new FreeNAS 0.7.2 Sabanda (revision 5226)
box recently using dd, in order to get an idea of write performance,
and when I deleted it the space was not freed.
Snapshots are not enabled:
bunker:~# zfs list -t all
NAME USED AVAIL REFER MOUNTPOINT
tank0 1.99T 707G 1.99T /mnt/tank0
bunker:~# zfs list -t snapshot
no datasets available
And there should be almost exactly 1TB used, not 1.99TB:
bunker:/mnt/tank0# zfs list
NAME USED AVAIL REFER MOUNTPOINT
tank0 1.99T 707G 1.99T /mnt/tank0
(I put 1TB of data on it, then created this 1TB file, so I know this for sure)
I removed the file using a simple rm /mnt/tank0/temp/mytempfile.bin.
It's definitely gone. But the space hasn't been freed.
I have been pointed in the direction of this bug
http://bugs.opensolaris.org/view_bug.do?bug_id=6792701
which appears to be in ZFS version 14, and my FreeNAS distro is at
version 13. Is this the issue?
I would really appreciate some help with this. The FreeNAS forums and
documentation haven't been any help.
Thanks in advance.
