How to re-mount custom storage volume created previously with API but migrated to snap

Hi
I’m manually migrating my containers to snap after a bungled migrate.
I’ve just imported a container but forgot to mount its “custom” storage volume in the new and proper snap location before importing so it didn’t auto import it.

I’ve now remounted the custom storage volume in what I think is the correct location:

/var/snap/lxd/common/lxd/storage-pools/default/custom/netconfigs

I’ve run the import again

/snap/bin/lxc import oxidized

but the custom volume still isn’t imported so the container won’t start

Any ideas if I can salvage it? Possibly remove the container without deleting it and re-import?

OK sorted it in the end, just need to create the volume again:

lxc storage volume create default netconfigs

Now it boots!
