LVM and Proxmox

[doma87]

I have two hosts with Proxmox installed. I connected each server with two 10 Gbit iSCSI links to a Fujitsu ETERNUS storage system. On the storage, RAID 5 is configured with a single volume. I have set up a multipath connection and I am currently using LVM. Is LVM the only option?


I tried LVM-Thin, but I cannot use it simultaneously on both hosts.

Hi @doma87 ,
Yes, LVM (thick) is the officially supported and safe method to allow for shared SAN storage in PVE

Hi, @bbgeek17

I tried to do it, but when I want to start the VM on another host, it says that the storage is locked and the VM does not start.

I am doing something wrong.

@doma87 , can you clarify what do you mean by "tried to do it"? What is it?
The LVM-Thin is wrong, you should not try it.
If it was thick/regular LVM , then please provide some configuration data :
pvesm status
cat /etc/pve/storage.cfg
qm config VMID

journalctl -n 100 (after failure)

I didn’t understand correctly — I have configured LVM and it is working. What I want to know is whether there are other options for my described setup.

Does the documentation answer your question?
