Typical scenario: 1) Store at 5GB (5GB disk space) 2) 0.5GB of emails come in over the day increasing store 5.5GB (5.5GB disk space) 3) Following day people clean out there inbox and deleted items folders (1GB of items go in dumpster retention == 1 day) (4.5GB in store used by email , 1GB in dumpster, 5.5Gb disk space) 4) next day dumspter dumps the deleted items (4.5GB in store used by email 1GB of white space, 5.5GB disk space) 5) next day 0.5GB of emails come in over the day increasing store 5.0GB (5.5GB disk space)
This is typical Database behaviour (Oracle, SQL etc) It is memory that exchange gobbles up by default -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Chinnery, Paul Sent: Wednesday, 13 September 2006 00:46 To: Exchange Discussions Subject: RE: Priv grows 4 gig in 4 hours But, if Exchange needs more space, shouldn't it use up the actual drive space until such time as it hits it's store limit? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Webb, Andy Sent: Monday, September 11, 2006 5:16 PM To: Exchange Discussions Subject: RE: Priv grows 4 gig in 4 hours The actual drive space is completely irrelevant. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Chinnery, Paul Sent: Monday, September 11, 2006 10:14 AM To: Exchange Discussions Subject: RE: Priv grows 4 gig in 4 hours I found something rather interesting. As a temporary measure, I dropped retention time down to 2 days. Looking thru the event log entries, this morning's dumpster showed 0 bytes. Adding up all the user's mailboxes, I get 8.4 gig. Log entry said there is 2.3 gig available which means I should have another 5.3 free; which I don't according to Exchange. Today, I checked the actual drive space on the Exchange store partition. Total space = 18.9 with 6.51 free so only 11.39 is used. Which, in my Monday morning-muddled mind, has me wondering why Exchange isn't using the available drive space. It's almost like it's saying "I can't give you any more free space because there's none left on the partition." -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Webb, Andy Sent: Monday, September 11, 2006 10:41 AM To: Exchange Discussions Subject: RE: Priv grows 4 gig in 4 hours The initial growth was likely due to a) a mail loop, b) an old Outlook client or Mac client trying to send a message over the send limit, c) something else similar. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dean Cunningham Sent: Sunday, September 10, 2006 9:22 PM To: Exchange Discussions Subject: RE: Priv grows 4 gig in 4 hours Thanks Andy, your explanation, then means if the store file grows 4GB in 4 hours then the suggestion that the dumpster as the cause of the 4GB growth is not correct, as pointers are moved within the store file and there is no deletion until the expiry time. What Ed and you are saying that if in system manager you see mailboxes totaling 10GB, the dumpster may be the difference between what you see in the system manager and the physical size of the store file, depending on what your retention policy is. Which is valid, but does not explain the growth originally mentioned? Something else is causing the growth. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Webb, Andy Sent: Monday, 11 September 2006 13:07 To: Exchange Discussions Subject: RE: Priv grows 4 gig in 4 hours It moves the pointers in the store yes, but it means the data is in the store for X days and it doesn't show up in the user's mailbox size report. So it appears to be "missing". There's an event logged as part of mailbox cleanup that says how much data is in the dumpster and how much is eligible to be cleaned up. The store space isn't "white" until the DIR time expires, the online defrag runs, and possibly a backup is run. _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/read/?forum=exchange To subscribe: http://e-newsletters.internet.com/discussionlists.html/ To unsubscribe send a blank email to [EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] To unsubscribe via postal mail, please contact us at: Jupitermedia Corp.
