[PVE-User] Proxmox on DRBD and OCFS2/GFS

[Erick Zozoaga Gómez]

Hello,

We still have three clusters running the old v1.9 with OCFS2 (although 
it was never recommended by Proxmox):

  * One small two-nodes with DRBD Primary/Primary and OCFS2on top. Never
    had any problems.
  * One mid four-nodes with iSCSI(openfiler) and OCFS on top. Also on
    the same cluster we have another storage via iSCSI with LVM on top.
    Both are stable, (i think LVM is a bit more) but OCFS has been more
    flexible (qcow2, file system access, etc).
  * One mid three-nodes with FC and OCFS. Only once time it was
    necessary to do fsck (after 2 years), without loose any data.

If neccesary, I would use DRBD with LVM on top (as doc says).
It was a pity that there is no more OCFS2 support since v2.0, but as 
Eneko says, the good news is that we will have new storage options on 3.1.

Thank you Proxmox team!!
