We’re running low on available disk space, so I cleaned up our mailbox databases and made available up a bunch of whitespace.
That whitespace is being used up in an expected fashion, however, I am noticing that some disk space is also/still getting used up. For example, here is one of our databases over 3 dates:
Date DB size Whitespace Free disk space
July 14 -- 955.7GB -- 31.19GB -- 8.75GB
July 22 -- 955.7GB -- 29.13GB -- 8.41GB
July 23 -- 955.7GB -- 27.44GB -- 8.35GB
Is this normal and part of an overhead of disk space that gets used, despite having available whitespace?
And if so, is a daily 4-6% overhead/decrease to be expected?
Note. The drive in question is holding only that database, nothing else (logs on a different drive, OS on a different drive, etc).
