Linux Virtual Server (http://www.linuxvirtualserver.org) Do all of these (or IPVS or Cluster Suite/GFS) take care of real-time sharing of storage (sessions, database, files, logs) between all nodes? For a LAMP or JEE or any other HTTP stack serving anything but readonly static files, this is usually a requirement. GFS is for sharing filesystem I know and there are howtos. So would you put Balance or LVS on top of GFS, or... Would HA/DRBD be on the short list? http://www.drbd.org/ in our case we have a two-node cluster anyway so this seems like the most straightforward option. Or would something else be superior, more up-to-date? Sam
