Ceph » Orchestrator

If OSD nodes have logical drives and I want Ceph to use the partition of the drives it won't work. It's because lsblk that comes with the container doesn't report the partitions as partitions and therefore ceph-volume ignores them. Could the lsblk be upgraded to a version that reports the partition correctly? Also, if there is a workaround I would be very intereted in learning it.

Here is an example:

# grep PRETTY /etc/os-release 
PRETTY_NAME="Red Hat Enterprise Linux 9.3 (Plow)" 

# cephadm version
cephadm version 18.2.1 (7fe91d5d5842e04be3b4f514d6dd990c54b29c76) reef (stable)

# cephadm --image d2cdd87030d1 inspect-image                            
{
    "ceph_version": "ceph version 18.2.1 (7fe91d5d5842e04be3b4f514d6dd990c54b29c76) reef (stable)",
    "image_id": "d2cdd87030d19393788f48f06e1a453e100160debff5a32c6b537a2b2e450e8e",

    ]
}
