I have a 2012 R2 server running hyper-v, with several 2012 R2 guest VMs.
These were stored on a small raid 5 volume of 4 disks, and 2 of them failed. I managed to recover the array to the point of moving the VM storage to another volume.
When starting two of the VMs, one has a BSOD that complains about a page fault in non paged area. Even after removing and recreating the VM using the existing disk, I got the same error. Bit confusing as this references a memory issue, so not sure why this would persist after a recreate?
Mounted the VHD and did a check disk, and came back ok. Not sure if there are any other things I can try to recover this?
The other VM oddly, boots but exhibits some odd behaviour. Pressing start, the start menu is blank and search doesn't work. Also, the only application that was on that VM seems to have it's install directory, but the main executable is missing?!
EDIT As Massimo pointed out, you cannot recover a RAID 5 volume from two failed disks. What I should have said, was 1 failed disk and 1 unconfigured bad disk. The unconfigured bad disk was marked good, and re-added to the array to allow it to mount again.
