Cannot Delete Obsolete Remote Snapshots

Good afternoon,

I am now running the RC 25.04 and trying to bat some cleanup, successfully deleting the iocage files left over from CORE on my SCALE system, along with associated snapshots. One on my remote replication target has remained persistent and is presently impossible to kill.

Let’s Encrypt can be found at iocage/releases/13.1-RELEASE/root and it consumes 2GB of space. How do I smite it since the GUI won’t let me, claiming it has dependent clones even though all other iocage snapshots were eventually cleared to be deleted?

Was “letsencrypt” created as a “clone jail” instead of a “base jail”?

Since you’re on SCALE and cannot automatically “delete the jail” and its ZFS components, you can check with this:

zfs get -t filesystem origin | grep letsencrypt

Ah, you are amazing! It pointed me to a very obvious problem - I should have deleted the remote /iocage dataset before attempting to delete its associated snapshots. Once I deleted the dataset, all snapshots disappeared also. Thank you!
