Failed to destroy snapshot

[mo100]

Hi,
I am running freenas 9.2.1 and have recently started receiving many error messages regarding the failure to auto delete the older snapshots from my system.

Feb 26 23:01:19 freenas autosnap.py: [tools.autosnap:58] Popen()ing: /sbin/zfs get -H freenas:state freenas/Media@auto-20140218.1000-1w
Feb 26 23:01:19 freenas autosnap.py: [tools.autosnap:58] Popen()ing: /sbin/zfs destroy -r -d freenas/Media@auto-20140218.1000-1w
Feb 26 23:01:19 freenas autosnap.py: [tools.autosnap:254] Failed to destroy snapshot 'freenas/Media@auto-20140218.1000-1w': cannot destroy snapshot freenas/Media@auto-20140218.1000-1w: unsupported version or feature


Since receiving the errors I have updated from 9.2 to 9.2.1, (importing my previous config), still the error message persist. I have from the command line destroyed all the snapshots with the hope that when they were recreated with 9.2.1 perhaps they could be deleted without issue, but no. The error messages have returned.

It seems to me I perhaps have inadvertently made a change when fiddling with plugin jails, but I don't know for sure. This is something I was doing around the same time the messages began occurring. Is this something to do with permissions?

I'd appreciate any advice.

Thanks,
MO

I too am having this issue - I presume there's an issue between my 9.1 Release jail and my 9.2.1.1 base system?

Anyone know what is causing this issue?

I too am affected. I have nothing running on my system, yet I can hear my disk churning on these tasks.

I used this guide to manually delete ALL snapshots & then I recreated the snapshot task.

All my snapshots are gone (I'm ok with this) & the churning of my disks has stopped . . .

I had to rerun those commands because I was getting the same error & constant disk churning again. It's been about 2 weeks (the length of I allow my snapshots to live).

What's the deal?
