hotadd disks visible in Disk Manager on Proxy

Veeam Logoby natalron » Fri Nov 29, 2013 6:41 am

Hi All,

I have an issue in that I am using a Veeam backup proxy for hotadd backup.

But some of my target VMs are visible in the proxy servers disk manager as mounted drives after the hotadd.

This then triggers alerts in my monitoring systems for disk threshold breeches. etc.

Most VMs disks appear in the proxy server as "offline" disks, but some actually are mounted and assigned drive letters.

Trying to determine why this is the case ...

Thanks in Advance,

Nat

Ronnie, having disks of the backed up VM attached (I believe, in read-only mode) to the proxy server is completely expected behavior. This is just how hotadd mode works. Are you saying that those disks remain attached to the proxy after the backup completes?

Hi Alexander,

Thanks for the reply. What I mean is .... that always the disks of the backed up VM attach to the proxy server, which I understand is normal.

But mainly the drives are shown in the proxy server disk manager as "offline" disks ... but for some VMs they attach and mount with a drive letter .. then my monitoring software detects the drive added and sends a disk threshold alert.

Does that make sense?

Thank you.

Cheers,

Nat

I believe that you'd better contact VMware team with this issue, since the Hot Add functionality is orchestrated solely by VMware, while, VB&R just appropriates it in order to backup VMs. Thanks.

Ronnie, can you please update this topic with the reason why some disks are online and some are offline during hotadd process? Meanwhile, I will try to reproduce it my labs. Thanks!

Yes. I can add more details after I have spoken to VMware and determined why some disks are offline and some online during the backup process. Cheers.

[MERGED] veeam reconfiguring vm

Veeam Logoby arsprod » Fri Feb 21, 2014 5:38 pm

I've been having one vm show up now daily with multiple hard drives attached that shouldn't be. The vcenter db looks fine as does everything else so I suspected veeam might be involved. Sure enough, as soon as one of my replication jobs starts this vm (not the one replicating) reconfigures itself and adds hard drives. The vm that adds drives is a veeam proxy. Anyone else see this bizarre behavior?

Aaron, this bizarre behavior is nothing but hotadd transport mode in action.

Oh... well don't I feel stupid! I'm assuming this is new to 7 since I've not seen it before? Do the disks stay there or supposed to be removed once the job is finished? Thanks

HotAdd mode is not new to v7 and disks are not supposed to be left on the proxy server after job finishes. If you see otherwise, I would recommend investigating this issue with the support team.

[MERGED] Disks remain connected to backup proxy

Veeam Logoby Guido » Tue Mar 04, 2014 10:20 am

There are 11 disks connected to my proxy backup server. No backups are running at this time. Some disks belong to other production vm's and some from replica's.
How can this happen and how to resolve?

Guido, most likely you're backing up in hotadd mode, so disks attachment to the proxy server is totally expected (see above for details). However what is not expected is that the attached disks are not removed after the backup, so I suggest contacting support to investigate that. Thanks.

[MERGED] Hotadd disks not released.

Veeam Logoby Peejay62 » Mon Mar 31, 2014 1:11 pm

Every now and then I notice that disks processed with hotadd are not released from a proxy. Is this something to live with or should this always work, releasing the disks after the backup completes?
Just as a workaround we made a script to check the proxys if they have "unwanted disks" mounted and release them if appropriate. I have been digging in some logfiles to see if there are any messages on not releasing disk, cannot find anything though.
SO any experience or suggestions on this?

thanks, Peter
