Ran across an issue today where there was 500GB of "missing" space on one of our drives.
System reported it as in use, but if examining folder usage, it came to nowhere near the amount of space the system saw being used.
Upon poking around and talking with my IT department, they found that a Shadow Copy had been created on the machine (for about 590G). That is where the missing space was. WE do not utilize VSS for anything and it is disabled by default in our server templates.
So... question is... is this another remnant of something that the conversion process to SmarterMail 17 left behind like the XML files and such? Another sign that the process didn't really fully finish?
Not blasting SmarterMail here at all, just want to know if they are the source of this VSS or do I need to continue looking for some other rogue process that created it?
Figured this may help MANY others if it really is an SM upgrade issue in reclaiming missing drive space, hence why the question is here and not issued as a support ticket directly.
