Cannot add disk to Ceph OSD in cluster


Apr 2, 2020

I have a 3 node cluster, crated OK. I want to create Ceph storage cluster for important VMs.
Furthermore, I have added to each host iSCSI drive, and created LVM on top of it. But seems that Ceph does not like that drive to be added as OSD.

Is this limitation of Ceph config in PX or Ceph limitation in general or am I doing something wrong?
My central storage allows only iSCSI drives and I have quad 10GB link to and from and between nodes - so I want to utilise it. So is there any official or even "unofficial" way to add those "remote" drives to be used as OSD drives in my Ceph cluster?

Thank you!
Some screenshots of what I mean, for help. If anyone has anything, please...
Thank you!
