Ignitenz Posted March 30, 2017 Share Posted March 30, 2017 I'm wondering if someone can help me, or even if this is supported. I'm relatively new to KVM Snapshots. I have tried this on Windows Server 2016 Windows Server 2012 R2 Things I have tried: virsh domfsfreeze DC1 This command gives me: Froze 2 filesystem(s) But in Windows, I see events such as: Event ID 8: The flush and hold writes operation on volume C: timed out while waiting for a release writes command. Event ID 12293: Volume Shadow Copy Service error: Error calling a routine on a Shadow Copy Provider {3629d4ed-ee09-4e0e-9a5c-6d8ba2872aef}. Routine details CommitSnapshots [hr = 0x80004004, Operation aborted]. Operation: Executing Asynchronous Operation Context: Current State: DoSnapshotSet Event ID 12340: Volume Shadow Copy Error: VSS waited more than 40 seconds for all volumes to be flushed. This caused volume \\?\Volume{f610b574-cfcc-40c7-8aa2-5be2d28b8525}\ to timeout while waiting for the release-writes phase of shadow copy creation. Trying again when disk activity is lower may solve this problem. Operation: Executing Asynchronous Operation Context: Current State: flush-and-hold writes Volume Name: \\?\Volume{f610b574-cfcc-40c7-8aa2-5be2d28b8525}\ Event ID: 8194: Volume Shadow Copy Service error: Error calling a routine on a Shadow Copy Provider {3629d4ed-ee09-4e0e-9a5c-6d8ba2872aef}. Routine details CommitSnapshots [hr = 0x80004004, Operation aborted ]. Operation: Executing Asynchronous Operation Context: Current State: DoSnapshotSet I also tried virsh snapshot-create --quiesce DC1 Which gave me: error: Flag 'VIR_DOMAIN_SNAPSHOT_CREATE_DISK_ONLY' is required by flag 'VIR_DOMAIN_SNAPSHOT_CREATE_QUIESCE' Google has failed me here. I'm just after a snapshot of the VM that Quiesce's the guest! Has anyone had any luck with this before? VSS is giving me hell, and I realize that's a Windows problem but I have never had this kind of issue in VMWare or Hyper-V before. Am I doing something wrong? I have guest agent v7.3.2 installed, I have tried earlier versions as well, to no avail. Is this just not possible/supported? Thanks in advance. Quote Link to comment
