Hello,
We have this strange issue - when I try to extend a .vhdx - the job fails, however the disk is expanded, but I need to run a Repair-SCVirtualMachine job afterwards.
Info about the enviroment:
Hyper-V 2016 Cluster with 16 hosts
HPE BL460c G9 blades running HPE 2018.03 SPP
The VM's are Veeam Replica VM's from a 2012 R2 Cluster, which has been made a Permanent Failover by Veeam.
If I tend to install a clean 2012, 2012 R2 or 2016 VM with bare OS, a Dynamic Disk at 30GB on the SCSI Adapter - and extends with 1GB, no problems.
So, it seems that were having issues with Veeam Replica VM's.
Any suggestions? :)
Error (12700)VMM cannot complete the host operation on the 'HYPER-V-HOST01' server because of the error: 'GUEST-DC01' failed to modify device 'Virtual Hard Disk'. (Virtual machine ID 370A1ACF-15CB-4EDC-BEA6-71A766482296)

Recommended Action
Resolve the host issue and then try the operation again.
