I’m trying to figure out the preferred hardware / software setup for proxmox in my case . I’d like to be able to use the awesome storage replication features as well as be able to freely use migration across cluster nodes using the GUI. My hardware: 2x 8-bay Dell R520s (already own) Planned setup – 2x SSD - ZFS Raid 1 for OS, 6x 4TB HDD - ZFS Raid Z2 for VMs 2x 4-bay Dell R420s (already own) Planned setup – 4x HDD - ZFS Raid Z2 for OS and VMs The problem: The Proxmox installer gives both the R520 SSDs and R420 HDDs zfs pool names rpool but my 2nd ZFS zpool for my R520s (where I’d like to store the VMs) doesn’t match the storage ID or zpool name so I can’t get Storage Replication or migration working from the R520s to the R420s. R520 – rpool (OS) vm_tank (VM Images) R420 – rpool (OS and VM Images) I realize I could just go with all HDDs in the R520 and do Raid ZFS Z2 but I really like the idea of isolating the OS hard drives where its hardware feasible. Thoughts? Am I missing something obvious? I've read https://pve.proxmox.com/wiki/Storage_Replication https://pve.proxmox.com/wiki/Storage and searched the forums and haven't been able to figure it out.
