Hello, 

I am using ceph storage (rbd, cephfs and S3). 

Today, if I mount an rbd disk with the rbd map tool, it does not appear in 
the usable disks.
This is because rbd disks are not scsi or mdadm disks. 

Is it possible to add support for it? 

For example, add this to pool:

ls -l /dev/rbd/[CEPH-POOL]/
total 0
lrwxrwxrwx 1 root root 10 mars   2 09:02 vtl-disk00 -> ../../rbd0
lrwxrwxrwx 1 root root 10 mars   2 09:02 vtl-disk01 -> ../../rbd1
lrwxrwxrwx 1 root root 10 mars   2 09:02 vtl-disk02 -> ../../rbd2
lrwxrwxrwx 1 root root 10 mars   2 09:02 vtl-disk03 -> ../../rbd3
lrwxrwxrwx 1 root root 10 mars   2 09:02 vtl-disk04 -> ../../rbd4
lrwxrwxrwx 1 root root 10 mars   2 09:02 vtl-disk05 -> ../../rbd5
lrwxrwxrwx 1 root root 10 mars   2 09:02 vtl-disk06 -> ../../rbd6
lrwxrwxrwx 1 root root 10 mars   2 09:02 vtl-disk07 -> ../../rbd7
lrwxrwxrwx 1 root root 10 mars   2 09:02 vtl-disk08 -> ../../rbd8
lrwxrwxrwx 1 root root 10 mars   2 09:02 vtl-disk09 -> ../../rbd9

ls -la /dev/rbd*
brw-rw---- 1 root disk 252,   0 mars   2 09:02 /dev/rbd0
brw-rw---- 1 root disk 252,  16 mars   2 09:02 /dev/rbd1
brw-rw---- 1 root disk 252,  32 mars   2 09:02 /dev/rbd2

brw-rw---- 1 root disk 252,  64 mars   2 09:02 /dev/rbd4
brw-rw---- 1 root disk 252,  80 mars   2 09:02 /dev/rbd5
brw-rw---- 1 root disk 252,  96 mars   2 09:02 /dev/rbd6
brw-rw---- 1 root disk 252, 112 mars   2 09:02 /dev/rbd7
brw-rw---- 1 root disk 252, 128 mars   2 09:02 /dev/rbd8
brw-rw---- 1 root disk 252, 144 mars   2 09:02 /dev/rbd9

Thanks in advance
