There is no metadata for writer

Veeam Logoby jorgene » Mon May 13, 2013 7:15 am

Hi,

Backups began to fail on 2 different servers and systems during this weekend.

Task failed Error: There is no metadata for writer '{66841cd4-6ded-4f4b-8f17-fd23f8ddc3de}'. --tr:Failed to collect Hyper-V writer document. --tr:Failed to call 'CollectWriterDoc' on server ....

Anyone else got this error message? And i can't seem to find out what's causing this issue. Other then that the
Writer name: 'Microsoft Hyper-V VSS Writer'
Writer Id: {66841cd4-6ded-4f4b-8f17-fd23f8ddc3de}
is NOT listed on the servers when we run the vssadmin list writers

Both servers are W2012.

Writer <ID> is NOT listed on the servers.

Seems to be the issue, indeed. Furthermore, what can be seen in Application event log?

Additionally, if as the result of "vssadmin list writers" command execution you get totally blank page, then, it means that something seriously wrong with the VSS service on this system and you need to dig into this way.

Thanks.

I tried to compare the logs since 2013-05-10 (when the error started) but i can't find anything that seems related.
Other that the Hyper-V VSS Writer seems to have dissapered during that date.

These are left:

Found a solution !

The Microsoft Hyper-V VSS Writer may enter an unstable state if a backup of the Hyper-V virtual machine fails. If you run the vssadmin list writers command, the Microsoft Hyper-V VSS Writer is not listed. To return the Microsoft Hyper-V VSS Writer to a stable state, the Hyper-V Virtual Machine Management service must be restarted.

What does "vssadmin list writers" command show you? Have you had a chance to contact our technical team on this issue?

Microsoft Hyper-V VSS Writer is not listed. Are you running this on Hyper-V server? Please include support case ID for this issue.

The whole Hyper-V solution is just one big joke.

More failures of random kind that one should accept from "enterprise" product.

Hyper-V host restart (like normally one does with any Windows OS) usually clears the problem, but is less then acceptable!

Seb, posting such kind of feedback, like you say, is not productive at all. Instead, we would appreciate opening cases with our technical support and providing all the required information for each reported problem, which will allow us to research and address the issues you encounter.

All signs here point at issue with the Hyper-V itself. However, will be happy to work with Microsoft to research the issue, and have them produce a hot fix... just like we work with VMware in case of issues with vSphere backup. But in order to do this, we need customers with the problem reproducing reliably to open support cases with us. This really does not take much longer than posting on the forum...

There is no metadata for writer '{66841cd4-6ded-4f4b-8f17-fd23f8ddc3de}'.

Error is reproducable.
Any ideas?

Bernd, please include support case ID when posting about technical issues (as explained when you click New Topic), otherwise this thread will be deleted.

To clarify, are you running the backup job against Windows 10 VM?

Yes, the VMs are Windows 10 VMs. With Veeam 8.0 Update 3 Veeam runs on Windows 10 and recognizes my VM infrastructure.
