I am trying to gather the list of working (or soon to be working :) approaches for gathering the spare space off of multiple linux machines and having to show up as a single shared fs/drive/mount/block device/whatever at a single central machine. No HA concerns. Just say 10-20 machines, with with 10GB of free disk space, and how to get the into a single 100-200GB fs on some other machine (all on the same subnet if needed) Thanks! James
