Restore deleted images

Incus

incus manages a dataset in rpool/incus.

I seem to have plenty of deleted images :slight_smile:

zfs list -t all | grep images

I understand deleted images are required by containers and vms.

Two questions:

Is there a way to make vm/containers standalone? I guess it is what happens when you use --vm --empty

Is there a way to restore these deleted images so they’re shown again in incus image list?

Thanks for your time

You can’t restore the images as the only thing that’s left of them is their unpacked form as a ZFS dataset. The original image tarball (which is what the image fingerprint is derived from) isn’t conserved and so the image cannot be correctly re-imported.

Now if the image still exists on a remote server, Incus will download the image files once again and will not unpack them given that an unpacked copy already exists.
Instead the dataset will be renamed back to images/ from the current delete/images/
