Now I'm a little bit unsure if this is connected with a wrong detecetd storage type. I've one running container. A diffrerence which I can see is that it's a privilged container:
/var/lib/lxd/storage-pools/default/containers# ls -l
total 0
drwxr-xr-x 1 root root 34 Dec 23 16:43 ubuntu-mail
drwxr-xr-x+ 1 165536 165536 78 Dec 21 12:35 ubuntu-minimal
So
- ubuntu-mail is starting fine
- ubuntu-minimal does not

Note that putitng your /var/lib/lxd on btrfs will NOT make LXD use btrfs optimized container storage.
The only way it would do so is if your storage pool is using the btrfs driver (you can check that with lxc storage list).

The most likely issue here is that your permissions on /var/lib/lxd itself are wrong as a result of you manually mounting a filesystem over it.
They should at a minimum be 0711, otherwise unprivileged containers will not be able to start (as is the case for you).

lxc storage indicates that btrfs should be used:
lxc storage list
+---------+-------------+--------+------------------------------------+---------+
| NAME | DESCRIPTION | DRIVER | SOURCE | USED BY |
+---------+-------------+--------+------------------------------------+---------+
| default | | btrfs | /var/lib/lxd/storage-pools/default | 10 |
+---------+-------------+--------+------------------------------------+---------+
The /var/lib/lxd folder seems to have the minimum of the required permissions:
ls -l /var/lib | grep lxd
drwxr-xr-x 1 root root 234 Dec 26 22:24 lxd
Can you tell me the permissions on the following:
- /var
- /var/lib
- /var/lib/lxd/containers
- /var/lib/lxd/storage-pools
- /var/lib/lxd/storage-pools/default
- /var/lib/lxd/storage-pools/default/containers
- /var/lib/lxd/containers//ubuntu-minimal
- /var/lib/lxd/containers/ubtuntu-minimal/rootfs
That should tell us why you're getting that permission error.

Note that lxc.log showing the "dir" backend is a red herring, that's because LXD always does the mounting itself and so liblxc then is always told to just treat the container as a plain old directory.

I'm a little curious what happened since it worked several weeks without problems...

As you expected it was an permission issue:

drwx------ 1 root root 110 Dec 26 05:05 containers
Changed to 755 (like fresh installation) and the containers starts again.
Thanks for having a look into the issue!

I had the same issue, which was fixed with a chmod 755 .../containers. I have no idea how the directory got in that state.

I just got /data/lxd/containers permissions reset to wrong ones on two servers by something (snap auto update?):
root@backup01 ~ # ls -l /data/lxd
total 0
drwx------ 1 root root 198 Jan 24 03:34 containers
Not sure what's causing, but it's yet another time I'm seeing it.
