Multiple Proxmox Hosts Sharing the Same iSCSI Target
- Thread starter wavesound
- Start date
At a high level to get shared iSCSI storage with Proxmox cluster you need to:
a) Make sure you present the LUN to all nodes. It should be visible via "lsscsi" (not installed by default) or "lsblk"
The LUN can be presented via Proxmox native iSCSI integration in GUI/CLI or manually via iscsiadm.
b) If you have multiple paths/interfaces - you need to configure multipath on each system
c) As @LnxBil said you then need to layer LVM-thick on top of the LUN from one of the nodes.
The easiest approach is to do it via PVE so that a storage configuration object is created at the same time.
From this point on new Virtual Disks (images) will be created as LVM slices by PVE from the storage object. The idea is somewhat similar to vVols.
Keep in mind that snapshots are not supported with LVM thick.
