I'm using LXD 2.20 on debian stretch, installed using snap and a LVM storage backend for my containers.
Everything worked fine until i tried to change the lvm fs type
lxc storage set lvmpool volume.block.filesystem xfs
lxc launch images:debian/buster testcont (a new image) results in the command downloading the image but not terminating. i had to terminate pressing Ctrl-C thrice. 'lxc list' shows the container, but 'lxc start testcont' does not start the container. it also does not terminate.
Containers which were created earlier can still start.
Deleting all containers, all images and all volumes does not help.
Switching back to ext4 using
lxc storage set lvmpool volume.block.filesystem ext4 does not help either.
If you need more information i would be happy to provide. Thank you for helping.
