Can you show output of lxc config show <instance>/<snapshot>?

Also does it work if there is no snapshot on the instance?

this process will always exist，The snapshot cannot be deleted

Thanks, it shouldn’t be needed as you’re container has its own root disk (shown from lxc config show without the --expanded flag).

11

Can you try refreshing to the latest 4.0 LTS release, LXD 4.0.9

snap refresh lxd --channel=4.0/stable

Which should get you:

4.0/stable: 4.0.9 2022-02-25 (22526) 71MB -

That will rule out if the issue has already been fixed in a later release.

thanks,i’ll try it
