There are three LVMs provided by XenServer 5.6 to the VM: xvda1 10GB Operating system (24% used) xvdb1 536MB Swap partition xvbc1 214GB backup storage (72% used)

What's the underlying physical disk look like? Could you have fragmented the VM image in the upgrade process? -- Les Mikesell [email protected] ------------------------------------------------------------------------------ Using storage to extend the benefits of virtualization and iSCSI Virtualization increases hardware utilization and delivers a new level of agility.
