leap Micro is a transactional linux distribution using openSUSE packages from openSUSE Leap. It roughly follows SLE Micro (commercial)

The ceph csi containers can not load modules on this distribution yet (ZSTD compressed ko files). As there are exactly two modules to load a file ceph.conf in /etc/modules-load.d will do

rbd
ceph

In flatcar linux it was no issue to mount local disks for K8s in /mnt/local-disks. In leap Micro /mnt is read only so no local-disks folder can be created.

btrfs subvolume create /opt/mnt
# edit /etc/fstab and copy the mount line for opt, change the subvol to /opt/mnt and the mount point to/mnt
# UUID=... /mnt btrfs defaults,subvol=@/opt/mnt 0 0
vi /etc/fstab
mount /mnt
