iSCSI volume as vmfs

[ant12]

Hi,

is it possible using 2 hosts running proxmox and connect the 2 hosts to single LUN like we do it with vmfs on 2 hosts with ESXi and running there the virtual machines ? What should I do ?

Thanks.

First of all, a cluster of two Proxmox nodes won't work. They are based on majority voting, so if one node goes down, the other one fences itself. You are better off using three nodes, and if that's not possible, you need a third device that is configured as Qdevice.

Then, there is no cluster-aware file system that works as well with shared block storage like you know with VMFS. You only have only two options: LVM (non-thin) or ZFS-over-iSCSI. Both have their downsides, for example LVM doesn't support Snapshots.

Hi @ant12 , welcome t the forum.

@B.Otto is correct - there is no VMFS direct-match built-in feature in PVE. There are some 3rd party Open Source alternatives. You'd have to evaluate, install, configure and maintain them on your own.
