Proxmox 5 cluster: how to add shared storage to all nodes?

Question

linux

Actually, subject. Now a cluster of 2 nodes, I will add a third one in the near future. At the time of creation, ceph RBD was used as a shared storage. You need to add a disk shelf through FC (multipath).
The process of adding to one node is something like this:
1) Create disk groups, they contain virtual disks;
2) Map the moons to a group of hosts (my three nodes)
3) Create a VG from one of the nodes, something like this:
pvcreate /dev/mapper/3690b11c0005284d1000006215ad4a707
vgcreate pve-vms /dev/mapper/
3690b11c0005284d1000006215ad4a707 so that it can be seen on all three nodes at once?

Answer 1

Mount the device on all nodes in the same place and say in the webmord that it is "Shared".
