Jail Size (Plex) using more space than stated?

[rmccullough]

I have an iocage jail for Plex that says it is taking 118gb from the Storage screen:

However, when I look at the filesystem it is showing a lot less space used (when I omit my /mnt directory):

Code:

root@freenas[/mnt/vm/iocage/jails/plex/root]# du -sh *
928K    bin
3.3M    boot
4.5K    COPYRIGHT
1.0K    dev
2.2M    etc
7.5M    lib
241K    libexec
512B    media
512B    net
512B    proc
7.5M    rescue
483M    root
4.1M    sbin
512B    sys
2.6M    tmp
512B    upPlex.sh
 16G    usr
2.5G    var

I suspect this is due to the journaling of ZFS or from snapshots. What can I do to reclaim some of this space? I have 2 x 500gb SSD in mirrored config for my VM/Jails. I have about 70% used, and want to make sure I stay away from that 80% mark and right now my Plex jail is the biggest offender.

Any suggestions?

It looks like the space was being used by snapshots.
