Hi Everyone,

 

I’m working on a case where the “Perform Datastore Freespace Check” option has been disabled for all the subclients at every pseudo client in the environment.

I ran the Audit trail for last 365 days and could not find anything related to this setting changes.

Customer has recently (like a month ago) upgraded his Commvault version from 11.40.22 to 11.40.28.

He suspects that after this upgradation, the issue might have occured.

He noticed the issue last week when he received the alert in vCenter on datastore utilization during the backup window.

After checking with Arlie, I found that:

  • In versions prior to 11.40.8, the "Perform Datastore Freespace Check" was enabled by default if not explicitly set.
  • Starting with version 11.40.8, the default value is disabled (false) unless explicitly configured.

Can someone please guide me on how to enable the “Perform Datastore Freespace Check” option by default even after upgrading to a newer version.

@Naveen Kumar D yeah that is pretty interesting that I too could not find any "official" information about this change. Perhaps ​@Sougato Roy  could reach out to someone on the VSA team which I believe would be the ones that could provide some info on this change.

 

On the reverting the changes back you can do via GUI or XML.

 

If you have a lot of subclients, you can use the xml file shared here Setting Datastore Freespace Parameters (VMware command line)

Note: To modify all subclients under a backup set, use a command in the following form, omitting the subclient parameter:

qoperation.exe execute -af update_subclient_vm_datastorefreespace_template.xml -appName 'Virtual Server' -clientName xxxxxx -instanceName xxxxxx -backupSetName xxxxxx -datastoreFreespaceCheck 0|1 -datastoreFreespaceRequired 1-100

 

Hope you can get it reverted back without major impact.

@dude  Appreciate you pointing this out. I’ll look into it with the team and get back to you as soon as I have more information.

Thank you,

@Naveen Kumar D the other place I forgot to mention is Command Center. 

Protect → Virtualization → Hypervisors → VM Groups → Configuration → Options (edit)
