Hi, community! Please help me with SAS Storage on my Proxmox 5 Cluster.

I have 4 nodes with Proxmox 5. On each node there is a HBA adapter linked with Dell MD3200 storage by one cord. Every node "can see" drive from storage like /dev/sda with correct size and etc.
Next I configured cluster:
- pvecm create ...
- pvecm add ...
Next I configured LVM and shared it via GUI according this link https://pve.proxmox.com/wiki/Intel_Modular_Server
- fdisk ...
- pvcreate ...
- vgcreate ...
After that I create a VM Guest on first node with 50GB disk image on that LVM storage. And other nodes doesn't "see" that disk image via GUI if I click on the LVM volume group -> Content. On the first node that disk image will be displayed.
In that situation if I create a VM Guest with (any size) disk image at second node disk image on the first node will be corrupted by OS installation in second VM guest.

A have read forum and now very confused in this situation. I would appreciate if you could give me some advices to use SAS Shared storage on nodes in cluster. Should I use cluster mode in lvm-config (lvm-config --enable-cluster)?

please update to a current version

in an lvm update, we set the use_lvmetad to 0 in /etc/lvm/lvm.conf (which you can also set) which is necessary for all nodes to not try to cache the
disk information for lvm
