Directory on top of DRBD

[jagan]

Hi,

Is it possible to mount drbd logical disks as directory type storage in 2-node cluster PVE 3.4 (As shared storage).

We trying to setup 2-node cluster with DRBD as shared storage. LVM wouldn't support snapshots, so we are trying to understand is there any alternate way. And also we need thin storage which will help us fast backups.

Yes, with OCFS2 as filesystem for both nodes AND a real switch for the interconnect, not direct cableing.

With an external tool? PVE itself performs "fast backups" of disks, because only the non-free space is backuped.
