Yes, don't use zfs for ceph. It's not officially supported, and as ceph use specific features of each filesystem (xfs, ext4 and btrfs), I can't recommand to use zfs in production. xfs is the current recommended filesystem for ceph osds. ----- Mail original ----- De: "Eneko Lacunza" <[email protected]> À: "proxmoxve" <[email protected]> Envoyé: Jeudi 19 Février 2015 15:17:45 Objet: Re: [PVE-User] Proxmox VE 3.4 released!

I don't think it's a good idea to build Ceph on top of ZFS. Ceph expects to give it full hard disks for storage and using ZFS with multiple disks will degrade performance.
