Ceph storage to block device

[vincentjanv]

Hi all,


So we're running a 3 node cluster with Ceph storage (single pool). Now we want to access the Ceph storage as block devices, but all guides I'm finding on the intenet, all refer to eg /dev/rdb/POOLNAME etc, ... I know we did succeed in getting a block device for an existing pool in the past, but now, we only see 4 ceph-xxxxxxx folders located under /dev/ . Adding a new pool and block storage is not the problem, but I need to access the current Ceph pool as a block device. Has something changed compared to older versions?

We're running Ceph 14.2.8-pve1 and Proxmox 6.1.8

Edit: for clarification: we need to provide the path to the block device, when using Virtualizor, if we want to manage our nodes there.

RBD images or only mapped to Block devices when krbd (kernel client) is used. Otherwise, qemu communicates directly through librbd with the cluster. This also only maps single images, not a pool.
