In order to avoid having to setup a NAS system, I am considering the possibility of setting up a dual-primary with DRBD to handle RAID1 over IP.

Concerning filesystems, I know of OCFS and GFS as distributed filesystem. I am leaning towards OCFS as that seems like the more reliable option.

Do you have any production experience with such a system ? Am I heading towards trouble ? What should I expect/plan ?

  • With what protcol do you want to provide your NAS service and why do you need the dual primary mode for this? – Nils Jan 01 '12 at 20:32
  • NAS would be NFS. I need it for redundancy :) – Antoine Benkemoun Jan 02 '12 at 07:21
  • And you want to run a NFS-server on both sides with the same ip (else the NFS-handle for the same file will be different on both nodes)? Then you need a load-balancer in front of that construction. For NFS you should rather fail over (active/passive) and run halv of the nfs-exports on one side, the other one on the other side. – Nils Jan 02 '12 at 22:08
