Hi Thomas,
I should have been more clear in my explanation. We have a two
physical node drbd cluster with GFS2. We have tried to add two more
nodes by increasing the gfs2 journal to four, the two in the drbd
cluster and two separate nodes; all four with gfs2 formatting. All four
nodes are connected via virtual machine (KVM) virtio disks. We can
access them but they do not maintain synchronization.
Becoming frustrated (only a little :-), we went back to the two
with drbd and gfs2. We then tried to connect with two more nodes (a
total of four) via iscsi. That didn't seem to work either. Anything
you can tell us would be helpful :-)
Truly,
Mark

But how should ne these "just-gfs-nodes" be able to see or attach these
storage, since your drbd-device is _not_ shared to this hosts. Your
Nodes are not able to attch
I would suggest, you want to export your drbd-device through aoe, iscsi,
fcoe or whatever.
A high-available storage-server through linux-ha could be the name to
the next topic you open ;-)
