Failed Backup VMWare Consolidation

Few things to check

1. Make sure VM hardware version is latest.
2. Make sure VMware tools are running and up to date in status.

Checked. All up to date.

Could be related to a fix that was part of MR85 see → 

• Commvault is trying to consolidate the same VM several times

Did you already try the following:

• Perform consolidation
• Remove all snapshots from the VM
• Rerun the backup job

I have a few VMs in my environment FR30 who experienced something similar and managed to fix it by applying previous steps. 
 

@Onno van den Berg we've already tried that. One or two jobs then run through but then this error occurs again.

Hello @turbo1781 

After the backup fails or gets to a point where it is stuck, can you please check /vmfs/volumes/<vm-datastore>/<vm-name>/vmware.log ? If there are locks getting generated, this log will be helpful. 

Secondly, you mentioned automount is enabled? As per my understanding, it should be disabled. Can you re-confirm?

To end with, what is the version of vCenter and VDDK? They both should of same version, you can check vsbkp.log on the proxy/access node and check the VDDK version in it.

@Rajiv now we have disabled automount on the VSA Proxy. 

@turbo1781 please use automount scrub as well as it will remove some stale mounts if any.

@Rajiv unfortunately the same game again. a job ran through and now backup failed again. what else could be the cause here?

We also have other machines that run without problems and, as I said, there were no problems before the update.

Hello @turbo1781 Did you happen to check  /vmfs/volumes/<vm-datastore>/<vm-name>/vmware.log ?

I have now moved the Access Node to a different schedule. Unfortunately, that only achieved limited results. Now the backups run about 5 times and then the error occurs again. There are always other machines involved.

@turbo1781 

You can log a case with VMware & Support so they/we can check.
