I have a CSV-volume problem on which I have got stuck. I am attaching my minifilter below CSVFs, and during InstanceTeardownStart callback I am failing to save(write) metadata file with STATUS_FILE_INVALID. So files are already invalidated here.. also I can't use Pre IRP_MJ_SHUTDOWN that comes later, the same for query teardown. So how can I save metadata inside CSV volume during restart? See no possibilities..
I know that only the MS CSV developers can help with this, and don't know better place to ask this.
