Imported container wont start due to idmapped storage error

i imported a backup image into incus of an lxd container i exported on another system. that container was working fine. On incus (but also on lxd on another host) i get the following error after trying to start:

Error: Failed to handle idmapped storage: invalid argument - Failed to change ACLs on /var/lib/incus/storage-pools/jpool-zfs/containers/mail-archive/rootfs/var/log/journal
Try `incus info --show-log mail-archive` for more info

there is nothing in the log.

Have you tried this?

thanks, i would try it if i could figure out how to navigate to that location. after this:
/var/lib/incus/storage-pools/jpool-zfs/containers/mail-archive there is nothing in that directory… so where is /var/lib/incus/storage-pools/jpool-zfs/containers/mail-archive/rootfs/var/log/journal

ok something clicked from a long time ago… i mounted the pool for the container and was able to access the directories below that point. deleted the container’s /var/log/journal directory and am good. thanks
