Hi all,
The disk where the exchange databases are located at had only af few GB of free space. So i extended the disk from 1.75 TB to 1.8 TB. I had 50 GB free space after extending the disk.
A day after extending the disk, i noticed i had 150 GB of free space on the same disk. What could happen that the exchange databases suddenly shrank 100 gigs?
Thanks in advance!
If I remember correctly, the Windows default is to allocate 10% of the disk to restore points. It would be easy to recover quite a lot of disk if the restore point allocation was changed, or if restore points were disabled for that drive.
Perhaps ask the other IT staffers if somebody did an offline Exchange compression on that drive (though at 9GB/hour, I'm sure somebody would have noticed this.)
But what it sounds like is there was something fairly large other than the Exchange database on that drive before, and now it is no longer there.
