I am working on encryption based minifilter driver. I have a cluster environment with 2 machines and a stress script is running to down cluster nodes simultaneously so as to move cluster disk from one node to another and vice versa.
My encryption driver is installed on both machines. As one node goes down,my minifilter driver's Instance TeardownStart/TeardownComplete and Instance Cleanup callbacks gets called in response to volume dismount.After random number of iterations, bugcheck happens.
And i have checked that this issue happens after FLT_VOLUME: ffffcf807f1787f0 "\Device\HarddiskVolume64" volume has been dismounted.
Can anyone help me to understand root cause ?
Thanks a lot for any of your suggestion!
