[Linux-cluster] GFS over DRBD

[Christopher Hawkins]

I've been working with Gluster. It's good stuff, but more like a super-NFS
or Lustre than GFS. It's a client / server architecture where there are
exported filesystems on the server and the client mounts it; shared storage
is not required. It would be an alternative to a DRBD + GFS setup...
Depending on what you need, I think it might work for you. 2 node setup,
right? Can you spell out your clustering goals?
