Backup failing due to false positive version missmatch
All relevant rpms on the host are are 10.6.6
No errors on get all systems or ssh propagation
Since the backup is quite disruptive (stopping services and unmounting disks, effectively taking production systems down) it is critical to ensure that no time will be wasted and that the scripts really work
Well that is the line that checks the version, so it's working, not sure why you are getting the failure. I'd have to see the full log and a copy of the all-systems file to see what gives.
