On the Database partition in Svr 2008, Windows Explorer is showing free space to be much less than it should be
We are running Exchange 2007 SP2 on Server 2008 SP2, 64bit.We have 2 main mail dbs, 1 for Staff, 1 for Students that are stored on the D drive. The logs for the dbs are also stored on D drive.The size of D is 350 Gb.The total size of the DBs with Logs is 136GB.Therefore we should have 214Gb free, HOWEVER Windows Explorer is telling us that there is only 70Gb free space on D drive.Defragmentation is running successfully on both Dbs each night.Is Exchange caching space on the drive that isn't being picked up by Windows?Any help would be much appreciated.

This is where you need to be lear. It is not the Excact defragmentation. It is the online maintainance's - Online defragmentation.Ref to: http://technet.microsoft.com/en-us/library/aa996226(EXCHG.65).aspx, http://technet.microsoft.com/en-us/library/bb676537(EXCHG.80).aspx, http://technet.microsoft.com/en-us/library/bb676454(EXCHG.80).aspx & http://msexchangeteam.com/archive/2007/01/15/432199.aspx.Is Exchange caching space on the drive that isn't being picked up by Windows?No. It will not be the case. - Nagesh

Hi Nagesh,Thanks for the links.Our logs are being committed and are being cleared each day by our backup. However the "shinking" is not happening on the DB, I have found 1 other forum that talks about this, but no solution was given.... I am not seeing a flush event in the event log each night, however the logs are being submitted. Should there be a flush event when the logs are committed?Any ideas on how I can check the flushing of the logs is happening correctly?Many thanks

Hi, The problem proved to be several Shadow Copies that had been left on the disk. I believe this occurred when a VCB and Commvault backup tried to run at the same time. After I removed the shadow copies using "Delete Shadows oldest D:", until they were all removed, Windows Explorer was once again showing the correct Free Space value! Ta
