Shared disk for virtual machines on storage, how to do it right?

Question

linux

Hello. I want to make a mini cluster out of two hosts, on the servers there is 1 disk for the system, and on the storage I plan to keep a volume for virtual machines so that each of the hosts can use them. There are 2 Hosts connected to netapp storage via sas interfaces. I installed proxmox on the hosts, made a disk pool and 1 large volume on the storage. Tom made ext4 and mounted it on both machines, the problem is that if any of the hosts, for example, creates a file on a shared partition, then the other host sees the changes only after remounting, maybe I'm doing something wrong?

Answer 1

Give the bare storage LUN to proxmox, then screw LVM over it in the settings. Don't forget to check the "shared" box.
