Disk Read Error when migrating virtual machine from one cluster to another
Recently I was involved in a Private Cloud project and as part of the project, we were migrating some virtual machines from one Hyper-v cluster to another. The VM was apparently successfully live migrated to second cluster but after few seconds, the VM crashes and then cannot boot and gave below error:
After doing some research, we found that the storage that clusters were using were not supporting ODX, hence we disabled to ODX in the registry, by changing the registry key HKLM\SYSTEM\CurrentControlSet\Control\FileSystem\FilterSupportedFeaturesMode from 0 to 1.
Once the ODX was disabled, the live migration of virtual machines between Hyper-V clusters worked perfectly and no disk read errors were encountered.
Hope this helps for people encountering similar situation.
