I have been having a strange occurrence:
Host Running windows Server 2012R2 using storage spaces for the volume hosting VHDX files
Host Volume has never experienced any chkdsk errors
Gen 2 VM Running windows server 2012R2 with a D: attached through a SCSI Controller
Virtual machine will loose any visibility to its D: (Does not show in disk manager or diskpart) even though it shows as been attached in hyper-v
Virtual machine shows the following errors:
The IO operation at logical block address 0x640a58 for Disk 1 (PDO name: \Device\00000043) was retried. This one is shown repeatedly then eventually"Disk 1 has been surprise removed"
Rebooting the VM brings the disk back online and visible in the VM, after running chkdsk Bitmap errors are returned which i am able to resolve with a chkdsk /f
This has happened 3 times in the past couple months. What could be the cause, I cannot find anything that relates to a VM loosing complete visibility to its' vhdx file. All storage is local on the host where the VM lives (No SMB share, no possibility of this being network related)
