Virtualization and Containers

Hello, during the VSA Backup, the following error appears by some virtual machines: “Timeout waiting for HotAdd Mutex, VDDK Deadlock encountered”The backup job completes with one or more errors. The VM’s with the above error are not backed up, while the VM’s w/o the above error are backed up successfully.HotAdd Mode is in use. What can be done done to fix this?Best regards, Aleksandra

Helo team,Hello team,I have a problem when configuring Oracle Linux virtual manager, I have created a proxy (VSA) with Oracle Linux 8.5 OS but when I select the access node for the proxy it does not come out.Additional information proxy using VM installed in OLVM itself.Is there a requirement that is missing

I seem to have multiple servers that only show the C drive when doing a guest file restore. If I mount a whole disk I can see all the others. I have other servers in the same backup Plan that work fine, have very similar servers that work fine, I can’t tell why it isn’t showing. Anyone had this? I’ve logged a ticket but not much of a response so far

We have multiple Hyper-V VM having SAN LUN mounted, the Microsoft itself not provide the feature to take snapshot of VM if SAN LUN mounted on it.Please share the way to take backup and restore of that VM on commvault.

We have configure Hyper-v vm backup to Tape now there was one requets from client to take monthly backups to Disk for those VM.Since we can not create another sublclient for same VM backup, we created another backup setup then a deault subclien was used with Storage to disk policy for same VM.Now, my VM licenses are counted twice, why is it so and if there is any other way acheive my target? 

Hi, i believe that there is away to copy or make a shadow of a specific VM from comser to another one like active and passive, but unfortunately i don’t know how to perform that task.  

Are there any workaround to migrate from VMware to OLVM? CV can migrate from VMware to Oracle VM/OpenStack and migrate from Oracle VM to Red Hat Virtualization (OLVM). Thank you.

Hello,I’m trying to get our Azure local POC added into Commvault. I’m able to backup VMs and can restore out of place VMs but the restored VMs are not viewable in Azure Portal. Is there a time delay in synchronization? The restored VMs were viewable in Windows Admin Center. Thanks,Clayton

According to documentation, both azure files and azure disk supports snapshots of filesystem.https://documentation.commvault.com/2024e/essential/system_requirements_for_kubernetes.htmlBut I’ve tested the backups of AKS now with two different clusters. and both of them defaults with an warning in the log:Will be mounting live volume [pvc] to worker pod [container] since it does not support volume snapshotsAre there any other configuration that needs to be made to ensure azure files uses snapshots? Regards,John Robert

I would like to know if it is possible to use a backup made in VMware and perform the restore in a RedHat Openshift environment.In the cross hypervisor table it is not clear whether the conversion is possible or not. This issue arises when it comes to keeping backups for a few years and migrating the infrastructure from VMware to OpenShift.

I've set up a proxy by installing VSA but the Opensatck Client can't communicate with the proxy's virtaul server.Are there any other specific packages to install on the VSA or should this one be included in the configuration files?My Commvault version is 11.32.83 How can i solve this

Who can explain to me how the Incr to full backup conversion works. If for example i do a full backup of a VMware cluster under a certain subclient the next backup would be a incremental. If however i create a new subclient (under the same backupset) will the next incremental backup remain a Incremental or will it now become a Full ? Also if i took a full without any other scheduled backups to follow how long will that Full come into play for if i then added a incremental. I presume it would remain for the retention policy but i’m not certain. Thanks for any advice

During a case a question comes up. A big VSA environment with more than ten subclients. Template VMs should generally be filtered out.That is easy in Commcell Console. I set the filter on backup set level and this works for all subclients.How can I do this in Command Center?Setting all VSA filters on subclient level seems to be a step backwards in product development. I found topics in community but it does not fit for me.Thanks in AdvanceJoerg

We’ve done a big hardware refresh and are migrating all our VMs to a new Virtual Center. Our backup environment is not changing at this time so all the storage, media agents etc are all set up and happy already.I thought I’d take the opportunity to “modernise” our backups at the same time, starting to use plans instead of storage and schedule policies and hopefully get to the point where we can largely leave the java console behind and use the Command Center. Our Commvault environment is very mature (20 years) and a lot of work has gone into keeping it in good shape over the years, through many upgrades and hardware refreshes. It works beautifully. So I am pretty old school and very familiar with the old console. Not loving plans if I’m honest, we have two on prem blocks of storage and one cloud library, and we tend to keep everything on the same retention periods. We do use a lot of different schedules so I’m finding the concept where it creates a whole new storage policy for every sc

11.36.52I have had my VM backup performance drop off the cliff in the last week, trying to figure out some bits and piecesOne thing I see in the ‘Backup Job Details’ is the many VMs at 90%What is the actual status at this point?They seem to be here for a long time, so any thoughts would be appreciated  Thanks

Hello,Following our upgrade to version 11.36.46 (from 11.32), we have observed an unusual behavior during the browse and restore operations. The file systems are being randomly mounted either on the configured FRE or on one of the HSX nodes designated for server backup.Since the HSX nodes are still running on RHEL 7.9, the browse operation fails for clients that are on RHEL 8.*.We likely wouldn't have noticed this issue if the browse operation hadn't failed. Is this the expecetd way the system operates ?   Thanks

Hi Team,I'm encountering the following error when attempting to browse Guest Files and Folders:Internal Error [150994988] in CVSession while communicating with remote host [Remote system [10.191.192.4*CS0000FREL01*8400*8402].

It looks Commvault still only support RedHat 8.7 for access nodes in RHEV environment, this is a pretty old OS. Is there any time line when they want support 8.10 or 9.x for access nodes?

Hi,I have a scenario where I will need to protect VMware VMs which can be located either on Datastores from Storage1 device or Storage2 device.I will have 2 plans setup for this:Plan1 will backup VMs from Storage1 datastores to a backup Pool2 Plan2 will backup VMs from Storage2 datastores to a backup Pool1The issue is that Pool1 is tied with Storage1 and Pool2 is tied with Storage2 in the sense that if Storage1 goes down for any reason then Pool1 will be unavailable too. The same is true for Storage2 and Pool2.The other issue is that VMs can migrate between Storage1 and Storage2For these reasons I always need to have last backup chain available on the pool that is independent of the Storage device where VM is sitting during backup.Some time ago it was a default behavior to force Full backup after changing target Storage Policy and since my Plans use different Pools/SPs, then and that would basically solve this for me. But this is not the case anymore. So my question is: is there a way

Hi All, When a VM migrates from one vCenter to another Commvault creates a new backup set name for example original set name is defaultBackupSet but after migration under the VM client you get a new Backupset called defaultBackupSet_ vCenterName and a new default subclient, We’ve been disabing the subclient in the original Backupset but what is best practice for dealing with the old Backup DataSet and subclient. I hope the question makes sense,

Customer is on 11.32 and is having a problem with Job Results folder filling up on backups. They’re VMware Primary backup is done in the field to a local MA/access node. Backup is VM backups, mounting snapshot, backup, release snap, auxcopy later. VM in question is 8.5TB and erroring out over the weekend when no restores are being done. Synth full Saturday, Incr Sunday… error out with filled up Job Results.They’ve filled the job results folder up twice now, once at 100GB and now at 300GB, and don’t want to keep chasing this issue.Customer would like to know behavior of the job results folder usage in order to properly size remote locations for backups. When does it release space? Question for Job Results (it keeps filling up even at 300GB) - do we need space for:a. files (as explained with a massively complex formula) and VM space (2% of VM size)b. just VM space And then how can we minimize the space requirements?Thanks.Steve F

Good day i hope you are welli am struggling in terms of re-adding windows file system backups on commserv.the steps i took is re-installing the content store on a rebuilt server and setting up the configs for file server and point to commserv gateway. when running the final install to register, it said that it will register ;later with the gateway server due to the fact that it is in maintenance mode. i also did create the windows client on Comserv under client computers and when clicking on reconfigure, i dont think it linked properly with the content store from the rebuilt server.please help
