[2012R2 Server Randomly Rebooting (ErrorReport, VSS, Low Disk Space)]

I just recently stood up a 2012 R2 server running both the latest trial version of DrivePool and Scanner.  This server is replacing a WHS v1 server I had running for over a decade.

 

Randomly my server is rebooting.  The potential oddities I'm seeing:

- Task bar notifications of "Low Disk Space" for many of my hard drives in the pool, which are close to full capacity.  NOTE: I have other hard drives that have plenty of space in the pool.

- DrivePool Performance section states "Balancing... (0.0%)"

- Event Viewer Application section Errors (5 different Errors - 3 with Scanner and 2 with VSS):
