Re: Available Storage Space declines precipitously
The server does have anti-virus and anti-spam software installed. That
software does store its temporary files on the same volume, but the space
being utilized by those files is measurable and does not account for the
missing space.
The volume has 55 GB of space, just over 29GB is being used for the various
files on the volume, including Windows swap space, tmp files, log files and
everything else that is visible from explorer or the command line or
WinDirStat. But looking at My Computer shows about 9.7 GB of space available
on the volume. It was 10.4 GB yesterday and 26 GB last Friday.
That precipitous decline without concomitant growth in mail store or other
file sizes that's the issue. I am adding new storage, but growth of storage
space utilization of a GB per day when message store grown in in the order of
50-100 MB per day would make the investment in storage space inadequate very
quickly.

Re: Available Storage Space declines precipitously
Check the System Volume Information folder on the drive (you'll need to
unhide system folders and change the NTFS permissions on it to give you
access first, as by default you can't get into it). I've had the Volume
Shadow Copy Service give me grief building up snaps in the folder before and
eating up a ton of space. Of the 100+ servers we run, I've only ever seen
it happen on Exchange servers. If you use Veritas/Symantec Backup Exec it
will sometimes keep that service running and produce this issue:

If that's your problem, just stop the Volume Shadow Copy Service on the
server and all your space should be freed up again.

Re: Available Storage Space declines precipitously
Thanks Phil,
I hadn't intentionally turned VSS on, so hadn't even though about it being a
problem. I checked and low and behold, it was on. I'll have to watch for a
few days to see what happens, but perhaps you've solved this odd problem.

Re: Available Storage Space declines precipitously
No problem. I've seen it twice, both times on Exchange 2003 servers, most
recently a couple weeks ago, so it was fresh in my mind. Anyway, I turned
it off on the server that was filling up a couple weeks ago and it hasn't
been a problem since. Always good to have something monitoring disk space
for you of course, so you can catch issues like this before the users do. ;)
