snapshot backups failing with error code 13 for windows virtual machines and error code 6 for linux Virtual machines

Hello guys,

from 2 weeks ago i faced an issue ,all of VMs hosted on one of our hosts in a cluster with 8 host have been failed in backup procedure (windows vMS error code 13 and linux VMs error code 6).

I can ping that host from my media and master server, all LUNs are visible in host. I've defined new policy for those VMs and ran it but still failed. meanwile quising has been disabled but problem steal remains.

backup procedure is completed successfully for other VMs on other hosts.

Are there existing snapshots? That may result into backup failures.

Have you tried doing a vmotion to another ESXi host and run a backup? If that is successful then move it back to the original ESXi, run a backup and see if it works.

Thanks for your reply, there

Thanks for your reply,

there are not any previous snapshots, already i've moved the affected VMs to another ESXI, and backup completed successfully. but when i moved them back to the original esxi, backups failed again.

Ok so the issue points to one ESXi host. Are the ESXi hosts on same build level as well?

Have you looked at the VMware

Have you looked at the VMware logs on the ESX host when you start a backup?

The problem is clearly with the ESX host and not with NBU. 
NBU is merely reporting the error and troubleshooting from within NBU will not tell us where exactly the issue is.

You will need to troubleshoot at VMware level.

Can you take snapshots directly from VMware?
Is there sufficient disk space to take snapshots?

Thanks dear Marianne, direct

Thanks dear Marianne,

direct snapshot is possible.

disks are shared LUNs amoung all ESXIs within the cluster, however there is enough space.

ESXI logs are normal and informes completed taking and removing snapshot.
