Trying to delete snapshots, errors states "dependent clones"

[asw2012]

Hi,
I've been trying to delete some snapshots on FreeNAS 9.3 - See the errors attached when I try to delete them. I've also been scouring and searching for this particular problem, but I can't seem to find a solution - or one that I fully understand.

Thank You.

Does this not cover what you have to do :

Thanks for the reply, and it looks like it does cover what I have to do... but
I try and copy the command in and no information is displayed. I'm doing something wrong.

Code:

[root@15TBNAS ~]# zdb -d RAIDz2 |grep "%"
[root@15TBNAS ~]#

Why do you want to delete the jail template snapshots? Those are what your jails are based on.

I've had a problem with snapshots eating up all of the NAS space, over 6TB worth, and it's happening again. These are the last three snapshots that need to be deleted so I can free up about 6TB of space.

I highly doubt those snapshots contain 6 TB

I highly doubt those snapshots contain 6 TB

the last time I deleted all of the snapshots, 6TB appeared again. This is why I am suspicious of them.
I still have not been able to find a way to delete them.

As long as you have jails you cannot delete the jail templates, that is those snapshots
