Once again - Unable to create a snapshot of the virtual machine.
I have a brand new installation of Backup Exec 2010 R3 together with a new clean install of vmware vSphere 4.1u1 (with VCenter and 8 ESXi-hosts).
For some reason i cant make it take backup of all my virtual servers. about 75% of them work fine, but for the rest all i get is:
Final error: 0xe0009574 - Unable to create a snapshot of the virtual machine. The virtual machine may be too busy to quiesce to take the snapshot.
Final error category: Resource Errors
For additional information regarding this error refer to link V-79-57344-38260
From searching on the net i found out that this can come from many reasons. I think i've looked through most of them without any luck.
The VM's are normal windows servers (2003, 2008 and 2008 R2) with latest vmware tools installed. if i make a snapshot in vmware (with quiesce guest file system enabled) it workes fine and i can see vid vssadmin that vmware-tools is the provider. But when trying a backup it does nothing. It just skips and gives me the error. I get nothing in the eventlog and nothing in the logs on the vmware server. It looks like Backup exec gives up before even trying.
The latest i found out now is that if i configure Backup Exec to take the backup directly against the esxi-host, then it works. But then it will fail if the VM is moved to another host, so that is not a solution.
Other VM's work just fine so it isn't an access or rights problem.
One VM (an Active directory server) has the RAWS agent installed (and vmware-tools snapshot-provided then was uninstalled) and it fails with same error.
Do you have any ideas?
