Hello
I have a server 2012 R2 host with hyper-v.
In the hyper-v i have 1 virtual machine that is 1.6 TB in a SSD disk of 2TB (1.81 TB) which left me with 168GB available.
i did checkpoint to the virtual machine, and the checkpoint growth a lot. So from 168 GB free space, it turned to 40 GB free space. i then , wanted to remove the checkpoint. and the minute i deleted the checkpoint, the virtual server crashed and so the host was also crashed. when the host turn on and start up, i got blue screens and crashed again. then i got heart attack, cause its a production server... after i myself recoverd , i try to start up with Last Known good configuration, and somehow a miracale happend and the server turn on and startup correctly. now again i have 168 GB free space. and no checkpoints of course.
After a few days, i tried to install backup software, which did somekind of snapshot before the backup started, and the server crashed again with blue screens. again i started the server with Last known good configuration and now it's fine.
My question is why the checkpoint get the server crashed ? is it because of low disk space ? maybe hard disk fault ?
I also can tell that in the event viewer i see sometimes (every couple of days) some disk warning - The IO operation at logical block address 0x1b241d60 for Disk 0 (PDO name: \Device\Ide\IdeDeviceP0T0L0-0) was retried.
Please assist.
