[Gluster-users] how well will this work

[Miles Fidelman]

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
