Description of problem:
  With some specific disk configuration, Ceph cluster is created correctly, but some OSDs are not visible in USM.

  I have a cluster with following disk configuration on two nodes:
  All disks are configured as SSD[1].
  - NODE3: 8 spare disks (sizes: 11G, 11G, 11G, 1T, 1T, 1T, 1T, 1T)
  - NODE4: 8 spare disks (sizes: 6G, 11G, 16G, 100G, 1T, 1T, 1T, 1T)
  
  NOTE: NODE1 and NODE2 have different disks schema and on each of them was properly created 6 OSDs.

  Cluster creation success, but there is problem with adding 2 OSDs on each of the above mentioned nodes:
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    OSD addition failed for [NODE3:map[/dev/vdh:/dev/vdd] NODE3:map[/dev/vdi:/dev/vdb] NODE4:map[/dev/vdf:/dev/vdb] NODE4:map[/dev/vdg:/dev/vdc]]
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  And I don't see those problematic OSDs on the OSD summary page (Clusters->"CLUSTER"->OSDs).

  But when I check it directly on the nodes and in Ceph, all OSDs were created properly and are there:

  And also ceph knows about all OSDs (6 OSDs peer NODE1 and NODE2, 5 OSDs peer NODE3 and NODE4).

How reproducible:
  100%

Steps to Reproduce:
1. Prepare nodes for USM cluster and on some nodes prepare/use following disks:
    - nodeA: 8 SSD disks (11G, 11G, 11G, 1T, 1T, 1T, 1T, 1T)
    - nodeB: 8 SSD disks (6G, 11G, 16G, 100G, 1T, 1T, 1T, 1T)

  Disks were created via this command:
    `qemu-img create -f qcow2 ${IMAGES_PATH}${NODE_NAME}-${DISK_NUMBER}.img ${SIZE}`
  and configured as SSD[1].

2. Create Ceph cluster via USM, use 5GB journal.
3. Check the "Create Cluster" task and OSD summary page (Clusters->"CLUSTER"->OSDs)
4. Check the number and list of OSDs in Ceph.
  On the MON node:
  # ceph --cluster TestClusterA osd stat
  On the OSD node:
  # lsblk
  # ceph-disk list

Actual results:
  Some OSDs were properly created, but USM reports them as Failed and they are not visible there.

Expected results:
  All properly created OSDs are visible in USM.
