Whitespace vs DB File Size |
|
|
An information request to help me learn:
If my 1221 events in the event viewer on my Exchange 2003 box report a
whitespace size on the order of gigabytes after online defrag
completes, why is the file size of priv1.edb creeping up?
I thought that Exchange would "back-fill" into the whitespace before
the file size would increase....
Anyone have a good explanation for this behavior?
TIA
Gordon

1221 reports the space available within the EDB and STM combined. I |
suspect that your STM is fairly large and is the one with all the free
space in it. Have you got lots of OWA, POP and IMAP users?
Take a look at: http://support.microsoft.com/kb/195914 which will let
you break down the space reported in the 1221 between the two files. |

Mark-
Thanks for the KB link.
Actually, my situation is opposite of what you thought:
priv1.edb 12,858,184 KB
priv1.stm 2,097,160 KB
1221 for mailstore 6.523 GB
I have only a few OWA users, no POP or IMAP users.
I have been actively hounding users and assisting them with mailbox
organization (using and managing PST files) as we are on Exch2K3 Std
and for a while, we were in danger of reaching the 16GB limit. Now
after all the work, my total DB footprint is approaching the managable
state where I can institute mailbox limits that'll keep my mail system
from blowing up. I'm just concerned about the "creep" in the priv1
size... I'll check out the methods outlined in the KB article to see
where my whitespace lies.

Then the priv certainly shouldn't be increasing in size.
Given that you are showing a perceived 50% free space to database
ratio I think you'd be justified in pulling the store down and doing
an offline defrag on it. |

That's what i was thinking.
But what I wanted to understand was why my priv1.edb file size is
creeping up in size if there's so much whitespace....
Thx
