Hyper-V 2012 R2 generation 2 VM corrupted system partition after restart

-

hi

we have cluster running on windows server 2012 r2 hyper-v feature.

one vm has windows 2012 r2 standard os installed (generation 2) corrupted via restart.

vm has 3 virtual disks (vhdx) - first system (dynamic size), second sql_data (fixed size) , third sql_logs (fixed size)

yesterday, restarted vm , vm didn't come up, got error

- 'boot failed. windows boot manager'

- 'boot failed. efi scsi device'

looked 3 vhdx noticed first 1 (system) corrupted - partition , mbr gone inside vhdx.

second , third 1 ok, can mount them , access data on it.

it looks on first vhdx (system sql 2014 installed) partition corrupted, can't repair because it's says unknown partition.

there no updates applied vm, corrupted partition 40gb size (dynamical) 18gb of data used.

this first generation 2 vm have, others generation 1 without problems.

can please explain us, how can happened, since did nothing inside vm, cluster reports no errors, checking vhdx looks fine, partition inside got corrupted.

we find out happened, before deploy more win2012 r2 vm (gen2) in production envirionment.

thank in advance 

regards

mike
