You have two possibilities: 1) The easy solution is to have a NAS on your network with a network share that you will mount on all nodes at once (in Datacenter/storage/add CIFS or NFS). Then you can use this as target for your backups. You'll have to consider your network speek, the sizes of...

Hey Analius, TLDR: Directly ZFS on a shared LUN won't work because ZFS is not cluster-aware. Explanation: you should have a look at: https://pve.proxmox.com/wiki/Storage ZFS is a filesystem so it operates on the file level. For what you want to achieve you would need a shared LUN (all nodes...

So, for future reference, I answer my own question: On its own, ZFS is NOT cluster-aware. If you want to access a zpool from several machines at once, you have to build a cluster using such tools as corosync, pacemaker and fence your drives etc... (which is a whole other topic). Btw, LVM is...

Yes, LVM would work, I used it on another setup. This time I would like to use ZFS. It is working on iSCSI because the target expose the zvols. But can it work directly on a shared zpool. This sounds more like a ZFS question actually. So each Proxmox node would manage the zvols that are used...

Hi proxminent ! all my nodes see the LUNs (through 8Gb fiber, connected over a Fiber switch) the backend storage itself can provide iSCSI but over 1Gb

Dear Proxmox community :) I would like to build a Proxmox infrastructure with several nodes connected to a SAN through Fiber. I plan to store virtual disks on a ZFS pool which will then be shared through all nodes. One SAN disk will be seen as local drive (using device mapper/multipath) and...

Sorry to necro this thread, but I think I know what the problem is, for future reference: If you issue a Shutdown command on a VM than cannot process it (no ACPI), the task runs and tries its best before timing out. During this time the /var/lock/qemu-server/lock-100.conf is locked by this...
