LXC snapshots with TrueNas storagebox

[pizza]

Currently I'm using KVM and LXC on a NFS share on a Proxmox cluster, but it's not possible to make snapshots with LXC. Can ISCSI with LVM as shared storage be a solution. So create a single iSCSI LUN that can be shared for all nodes. Or any thoughts?

it not supported. lxc + snapshot works only on loca LVM, local ZFS or Ceph. I know it's bad, but I hope that proxmox will support qcow3 with lxc soon or later then u get snapshot with NFS

Using LVM-Thin on iSCSI (use LUN directly=disabled) works with LXC snapshots. What I did first create iSCSI (no LUN directly), so we have a block device (check it with lsblk). Then create LVM-Thin from console
