I've reconfigured my setup (good succes below, but need clarity on gluster option): Two nodes total, both running virt and glusterfs storage (2 node replica, quorum). I've created an NFS storage domain, pointed at the first nodes IP address. I've launched a 2008 R2 SP1 install with a virtio-scsi

I've enabled nfs.trusted-sync ( http://gluster.org/community/documentation/index.php/Gluster_3.2:_Setting_Volume_Options#nfs.trusted-sync ) on the gluster volume, and the speed difference is immeasurable . Can anyone explain what this option does, and what the risks are with a 2 node

Adding the virtio-scsi developers. Anyhow, virtio-scsi is newer and less established than viostor (the block device), so you might want to try it out. A disclaimer: There are time and patches gaps between RHEL and other versions. Ronen. On 01/28/2014 10:39 PM, Steve Dainard wrote: I've had a
