Hi Folks, I find myself trying to expand a 2-node high-availability cluster from to a 4-node cluster. I'm running Xen virtualization, and currently using DRBD to mirror data, and pacemaker to failover cleanly. The thing is, I'm trying to add 2 nodes to the cluster, and DRBD doesn't scale. Also, as a function of rackspace limits, and the hardware at hand, I can't separate storage nodes from compute nodes - instead, I have to live with 4 nodes, each with 4 large drives (but also w/ 4 gigE ports per server). The obvious thought is to use Gluster to assemble all the drives into one large storage pool, with replication. But.. last time I looked at this (6 months or so back), it looked like some of the critical features were brand new, and performance seemed to be a problem in the configuration I'm thinking of. Which leads me to my question: Has the situation improved to the point that I can use Gluster this way? Thanks very much, Miles Fidelman -- In theory, there is no difference between theory and practice. In practice, there is. .... Yogi Berra
