Hi, I know gluster doesn't like it's underlying filesystem to be changed, but what does it think of an XFS defrag? I ask, because I have a test system that just lost all of it's VM's after a reboot. The filesystem is software RAID-6 --> XFS --> Gluster NFS export. This is a test bench system that has been running for about 2 months. The problem here is that I have a duplicate live system that I put in place last week. Gerald
