Re: [Xen-users] guest OS High Availability with local storage
True, but I have not heard it being that slow before, also if you do go with gluster use 3.3. if you are looking for ease of setup gluster is easy. And drdb stops at 2 nodes doesnt it.

From my experience gluster write performance (2 mirrored nodes) is very low, approx 40-45Mb/sec. read is pretty high and it was network saturation - appr 90-95Mb/sec (i have gigi network). For HA for VMs i'd highly recommend DRDB+Pacemaker+Corosync. Solution is much more advanced, and requires much more efforts, but output will cover all time expenses. I have cluster of 2 nodes with DRBD, some VM images (block devices, using Logical Volumes on top of DRDB) are up to 512G. I don't see any performance loss. Also Pacemaker is well integrated with XEN live migration. So i think it's best solution for "cheap man".
