Having problems on my side using Netapp Hardware VSS and Veeam doing a by Volume Backup (on CSV).
Backup with Microsoft Software VSS is OK but using Netapp Hardware VSS, HyperV 2012 R2 cluster kills randomly one VMs during the transfer of the mounted LUN of Netapp's snapshot (VM Resource goes to Fail state, and VM reboots, and sometimes not the one beeing backuped but always one on same volume).
Installed lastest patches from Microsoft from 22 July but didnt help.( kb3072380 , kb3068445 , kb3068444 )
Didnt open any case with Veeam for now, since i know this will be a "ping pong" between Netapp saying their VSS is only supported on their backup products and Veeam saying that if backup is OK with Microsoft VSS, its Netapp's side. And by the way the backup is always 100% OK, even if some VMs are rebooted.
If someone has seen this problem, i'll be happy
