I had one site that were doing to many backups at once their SAN would lose connection to the VM. I have access to the guest so from my POV sda just "disappears". Root goes to read-only and kernel screams. Guest has to be restarted. This happened 3 times before they figured it out. 

"Turns out Hyper-V replication was using too many resources, causing the SAN to get upset, and the host would close random connections to the guest operating systems. 

I was paying attention to what you did last week, so I ran the fsck command and got the guest back online. Aaron changed the replication schedule on that server so the guests only replicate one at a time. Your guest isn’t one of them that’s replicating at this point."
