Can't delete snapshots: "must not have dependent clones"

Hello all, i have some snapshots took 2 months ago by the system itself.
I want to get rid of them, but i can’t delete them cause Truenas says they have dependent clones.

i’m assuming they were taken when migrating from core to scale…
how to do?
Thanks


Yes, the iX-applications dataset was cloned to provide a safe migration from dragonfish to electric eel… I assume that was the path you took.

We’'ll be deleting it by fangtooth… anything earlier is possible, but is not documented and has risk for downgrades.

i tried this solution and seems to work:

zfs promote SSD/ix-apps/app_mounts/syncthing/config
zfs destroy SSD/ix-apps/app_mounts/syncthing/config

also with app running, so seems to be safe.
tried to stop/start the app and nothing gone wrong.

i think i will do it for all snapshots

I have just upgraded to fangtooth and i’m still unable to delete old snapshots and get this same message. I have migrated all of my apps, is there any update on this?

I don’t know if other people have the same issue???


These are my snapshots that I cant delete.

Some of those apps I don’t even use anymore or have installed as apps

What do you think?

Do you still have your ix-applications dataset (not ix-apps) or have you already deleted it?

I do still have my ix-applications dataset yes. I dont have an ix-apps dataset though? I am using custom host path now though for all apps

It’s a hidden dataset:
https://www.truenas.com/docs/truenasapps/managingapps/#ix-apps-dataset

Ahh yes i can see thta in FTP now.

So if I have migrated all of my apps, I am okay to delete the ix-application dataset now?

Yes and if it does that successfully, it should also clear the dependent clones

Apologies for necroing this thread, but I’ve got the same problem with the same ix_apps snapshots. That docs link above isn’t working any more and I can’t work out if or where the current equivalent page exists (I’m on Community Edition 25.04.2.1), so could someone be so kind as to point me at the current page so I can try and get rid of these snapshots too?

Thanks, all.
