Hello,

I currently have several Dell Powerstore 1200T storage arrays (3) which are managed by a Metro Cluster that I use for iSCSI virtualization (VMware to be transparent and everything works fine).

I want to test Proxmox, and I used 3 physical servers to have a cluster of 3 hosts and I mounted a LVM LUN to test the stability of Proxmox through iSCSI.
After reading the documentation I noticed that I can't do snapshots with this storage configuration.

I can't use LVM Thin because the storage has to be shared across the 3 proxmox hosts.
From my point of view my only solution is to use " ZFS over ISCSI ", the ram consumption of ZFS is not a problem.

Do you have any idea how I could use ZFS over iSCSI with my powerstores or is my equipment not designed for this?

Thanks in advance for your reply.
 
Hi @AGS Cloud ,

There is no way to directly use ZFS/iSCSI scheme with your storage. The ZFS/iSCSI requires ability to:
a) ssh to storage box as root
b) storage should be using ZFS internally for volume management
c) storage must use supported iSCSI daemon that can be managed directly via SSH

None of this is true for your storage.

Good luck

You can use your Powerstore 1200T with iscsi like with your vmware installations before,
you can do the snapsshots inside the powerstore instead of with pve and you can attach it as a ha-nas fileserver with nfs (or smb) as well.
It's then all without zfs but works in different ways with pve.
