SOLVED [SCALE] Mass cleanup/removal of ix-applications snapshots solution required

[bnred777]

So I've read through this several times but I'm still having trouble trying to understand how to correct my 28000 snapshots. I am on bluefin but I still show 28000 snapshots. Can someone tell me what I should do to get this down to a more reasonable size? Would be nice to know how I should have snapshots setup in the first place. I followed a guide that has multiple snapshots running at different time intervals. One is set for every 15 minutes. Is this not what I should be doing?

Wanted to wrap this up by making it clear that SCALE Bluefin includes OverlayFS for ZFS. This removes all the excess snapshots.

I'll mark this as solved.

Blog - iX Collaborates to add native OverlayFS Support to OpenZFS for Docker & Kubernetes

TrueNAS SCALE Bluefin is adding the capability to natively support the Docker Overlay filesystem and its drivers. This significantly improves the handling and scalability of systems running many Container instances. Docker (and Kubernetes) uses an Overlay file system to manage the layers of...

Do i need to do something (other than upgrading) to enable this feature?

No.. just upgrade to Bluefin.

I've been on Bluefin and had tens of thousands of snapshots until using truetool (truetool.sh -p) to run docker prune. I still run it on a cronjob and I still have about 3000 snapshots in ix-applications/<various-uuids>... is this normal or what else do I need to do to remove them?

Sorry to write up in an old thread, but I have the same issue and I didn't understood if there is a way to fix this behaviour. I have no automatic snapshots tasks enabled, I just have the

Code:

bash /root/heavy_script/heavy_script.sh update

to run daily and it seems that everytime it runs it create snapshots of everything.
It's not a problem for me, but I would like to have the snapshots be pruned automatically after, let's say, 7 days.
Now, when clicking on any snapshot, I see this message

Code:

Retention:Will not be destroyed automatically

How can I enable an automatic prune?

You MUST create an automatic snapshot task that matches the naming schema of your snapshots exactly (Daily-%m-%d-%Y-%h-%m-%s, or whatever). Anything that is not a variable, “Daily”, hyphens, etc., must match EXACTLY.

It is the task itself that will perform pruning. There is no built-in self-pruning mechanism to ZFS snapshots.

The task will periodically search through all matching snapshots and prune them when they get too old.

Doesn't heavy_script prune its own snapshot - just not the other ix ones?
