Can't Delete Apps that were migrated over to Electric Eel from Dragonfish

Apps and Virtualization

Maybe I am being a total noob, but when I try to delete an app that was migrated over from dragonfish to electric eel that I no longer want, and i tick the box to remove ix volumes, i get the following error:-

middlewared.service_exception.CallError: [EFAULT] Failed to delete dataset: cannot destroy ‘Applications/ix-apps/app_mounts/pihole’: filesystem has dependent clones
use ‘-R’ to destroy the following datasets:
Applications/ix-applications/releases/pihole/volumes/ix_volumes/dnsmasq
Applications/ix-applications/releases/pihole/volumes/ix_volumes/config

The app appears to be gone, but If i reinstall the app, all its configuration and data is still there, so its not deleted its volume.

Am i being a noob?

I am a bit confused. You said you migrated from Dragonfish to Electric Eel. But from the data it looks like you are still running Dragonfish? Or do you have two systems, one running Dragonfish and one running Electric Eel?

EDIT: Nevermind, I see now that the ix-apps mount was cloned from ix-applications.

If all applications have been successfully migrated, you can delete the ix-applications dataset (NOT to be confused with the similarly named ix-apps dataset). You can’t go back to Dragonfish after deleting the ix-applications dataset.

Doing so might resolve your issue.

thanks, ill give it a go.

Okay so once 24.10.1 is released (it should be hopefully next week), you can run

midclt call --job app.delete APP_NAME_HERE '{"remove_ix_volumes": true, "force_remove_ix_volumes": true}'

That will delete the app and the ix-volumes as well but you should be careful when using the force flag as it will delete those ix-volumes and the dependent clones as well which are present in old DF apps.
