Since a few days, i expierience problems during snapshots of virtual machines. The error is reproducible on w2k8 r2 machines. Other os i didn't test at the moment.
Environment: VSC 4 VSphere ESXi 5 U1 Cluster NetApp FAS 3140 Ontap 8.0.1 P5 Shared Storage (NFS)
A quiesced snapshot of a vm fails with the following error details:
The guest OS has reported an error during quiescing. The error code was: 5 The error message was: Asynchronous operation failed: VssSyncStart
The guest OS has reported an error during quiescing. The error code was: 3 The error message was: Snapshot operation aborted
The guest OS has reported an error during quiescing. The error code was: 3 The error message was: Error when notifying the sync provider.
The snapshot doesn't get deleted after that so i have to consolidate these snapshot vmdk's by hand.
Scenario:
- Did a scheduled backup with quiescing option enabled (runs well for almost a year with previous vsc versions) SFR never made problems. Recently i did an update to VSC 4.0 cause i also update my VSphere Environment from 4.1 to 5.0 Update 1.
- Mounted the backup using SFR and can access it without a problem.
- Dismounted backup and deleted SFR session.
- Trying to do a snapshot again with quiescing optiion enabled which fails with the above error.
- Restart the vm and do a snapshot again which works without a problem (on another w2k8 server restarting didn’t fix it!)
The only additional information i see is an event in windows system log: The disk signature of disk 1 is equal to the disk signature of disk 0.
Another thing is, that the *vmx was modified and the disk mode changed: scsi0:1.mode = "independent-persistent" ???????????
What's going on here? I never saw this issues before!
Any help is welcome!
