GFS (or GFS2 fwiw) imposes a single, shared storage as its backend. At
least I get that from reading the documentation. This would result in
merging all the single disks via NBD/LVM to one machine first and
export that merged volume back via NBD/iSCSI to the nodes. In case the
actual data is local to a client, it would still be first send to the
central machine (running LVM) and loaded back from there. Not as
distributed as I hoped, or are there other configuration possibilities
to not go that route?
