Writes to my RHEL 5 GFS2 filesystem are faster than to my RHEL 6 GFS2 filesystem
Issue
When testing writes to a GFS2 filesystem in a RHEL 5 Resilient Storage cluster vs a RHEL 6 Resilient Storage cluster using a dd command as shown below, writes to the RHEL 5 filesystem are substantially faster than to the RHEL 6 filesystem:
# dd if=/dev/zero of=/mnt/gfs2/testfile bs=8k count=3000 oflag=dsync
Environment
