We have been seeing this error lately and figured to throw it out the group to see if anyone else has the problem:
When Extending (In VCenter Edit Option) a C Drive on a Windows 2008 Cluster node that is active, the server will shut itself off and I get the following error:
Failed to resume virtual disk scsi1:0. The disk has been modified since you took a snapshot or suspended the virtual machine. Error encountered while restarting virtual machine after taking snapshot. The virtual machine will be powered off. View details...
The virtual disk scsi1:0 is a RDM lun that's part of the Clustered Volumes. Not the C Drive (scsi0:0)
Im running ESX4.0 (208167)
Anyone have any ideas and why this is happening?
