We also have a shared storage, but due to serious performance problems with this storage, we are trying to get rid of it.

    iSCSI storage encryption for a cluster

    Hello, I am setting up a Proxmox cluster with 3 servers, and 1 shared iSCSI storage. It seems that I can only access this storage in iscsi mode (I asked a question about this at https://forum.proxmox.com/threads/zfs-via-iscsi.74843/post-378849) With this setup, what are my options for VM...
