RE: reclaiming space
You need to do an offline defrag to reclaim the space. -Andrew From: SMREKAR, JACK [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 25, 2008 11:44 AM To: MS-Exchange Admin Issues Subject: reclaiming space I have moved a couple hundred mailboxes from one Exchange server to another in hopes of reclaiming some space on the first server. In all so far I have moved about 120 gig of mailboxes to the other server but I do not see that space coming back on the first server. I do run the online maintenance of the databases that is built inside of the system manager. I also get emails nightly on what was done. Below is one that I got last night.

You will need to do an offline defrag to shrink the database. That would be eseutil with the appropriate commands in place IIRC.

Re: reclaiming space
I've always been curious and I've never been able to find a straight answer. Is there any benefit to running an offline defrag after you have migrated a significant amount of data from one database to another, other than regaining disk space? I recently migrated about half of my users (50GB) to another storage group (Exchange 2003 SP2) and was wondering if I should bother with defragging the original database. I'm not concerned about the size of the original DB as I have plenty of disk space. Sorry to hijack the thread but I figured it was relatively on-topic. - Sean On 3/25/08, Don Ely <[EMAIL PROTECTED]> wrote: > > Yes we do... > > On Tue, Mar 25, 2008 at 3:37 PM, Michael B.

RE: reclaiming space
If you have plenty of disk space, then the only NEGATIVE is that your backups take longer, as they still back up the empty space. A positive is that Exchange doesn't have to physically expand the database store when additional space is needed. Regards, Michael B.

RE: reclaiming space
Well, no. This is exactly the right case for an offline defrag. If you move a lot of mailboxes from a store then that is when you might consider an offline defrag. In this case some 549 mailboxes totalling something like 122.6GB. Jack, you can perform an offline defrag so you are not backing up excessive white space on that source server.

RE: reclaiming space
That is absolutely certainly another option. That way only the mailboxes in transition are offline from a server point of view. But we have no clue about what else is even on that source server, their SLA, whether they can support another store on that server, etc. He didn't even indicate the Exchange version. Though, I guess with 122GB moved, it had to be Exchange 2003 Enterprise and he probably hasn't used all his database options. From: Michael B.

RE: reclaiming space
As I recall, one of Microsoft's criteria for doing an Offline Defragmentation was that you had greater than 20% whitespace in the current message database file. Yes, once the offline defragmentation is completed, you will have zero white space and the MDB will expand as new mail comes in and whitespace will grow again as mail is deleted, but such is the nature of database files. Now as to the BRILLIANT suggestion that they just move all the mailboxes and then blow away the old database, what happens when you move all the mailboxes back to the original location AFTER blowing away the original MDB??? You've expanded the target MDB by that much and created a huge whitespace area on the other MDB. So, what have you really gained, other than the creation of a HUGE amount of transaction logs, on both the source and target servers? Oh, BTW, make sure you run a decent physical file defragmentation tool once you've completed the ESEUTIL defrag, like Perfect Disk 2008. That will help you get the file into a contiguous condition and help your disk performance quite a bit. John H.

RE: reclaiming space
Not sure why you would move the mailboxes back: if I'm not mistaken, what is being suggested is that a new store be created on the same exchange server, and the mailboxes be moved to the new store using the wizard and the old store then be removed from the system. This would mean, as already stated by Michael and others, the only downtime would be for the users whose mailbox were in the process of being moved instead of the all users; the end user impact can be further mitigated by scheduling the job to run afterhours and spread out over several days. Having used the same process several times in similar situations, I consider it to be much more advisable than doing an offline defrag. ...unless of course I misunderstood what was being recommended?

I am sure there was an assumption that this applied to Exchange 2007 or Exchange 2003 Enterprise and the administrator would create a new database and move the mailboxes and delete the original database. This would be on the _same_ server. There is no need to move the mailboxes back, John.

RE: reclaiming space
Nope, you understood correctly. Regards, Michael B. Smith MCSE/Exchange MVP http://TheEssentialExchange.com -Original Message- From: Amer Karim [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 26, 2008 12:46 AM To: MS-Exchange Admin Issues Subject: RE: reclaiming space Not sure why you would move the mailboxes back: if I'm not mistaken, what is being suggested is that a new store be created on the same exchange server, and the mailboxes be moved to the new store using the wizard and the old store then be removed from the system. This would mean, as already stated by Michael and others, the only downtime would be for the users whose mailbox were in the process of being moved instead of the all users; the end user impact can be further mitigated by scheduling the job to run afterhours and spread out over several days. Having used the same process several times in similar situations, I consider it to be much more advisable than doing an offline defrag. ...unless of course I misunderstood what was being recommended? Regards, Amer Karim Nautilis Information Systems -Original Message- From: Matteson, John H Jr USA Mr USA 25th SigBN (ITT) [mailto:[EMAIL PROTECTED] Sent: March-26-08 12:12 AM To: MS-Exchange Admin Issues Subject: RE: reclaiming space As I recall, one of Microsoft's criteria for doing an Offline Defragmentation was that you had greater than 20% whitespace in the current message database file. Yes, once the offline defragmentation is completed, you will have zero white space and the MDB will expand as new mail comes in and whitespace will grow again as mail is deleted, but such is the nature of database files. Now as to the BRILLIANT suggestion that they just move all the mailboxes and then blow away the old database, what happens when you move all the mailboxes back to the original location AFTER blowing away the original MDB??? You've expanded the target MDB by that much and created a huge whitespace area on the other MDB. So, what have you really gained, other than the creation of a HUGE amount of transaction logs, on both the source and target servers? Oh, BTW, make sure you run a decent physical file defragmentation tool once you've completed the ESEUTIL defrag, like Perfect Disk 2008. That will help you get the file into a contiguous condition and help your disk performance quite a bit. John H.

Is there any benefit to running an offline defrag after you have migrated a significant amount of data from one database to another, other than regaining disk space? I recently migrated about half of my users (50GB) to another storage group (Exchange 2003 SP2) and was wondering if I should bother with defragging the original database. I'm not concerned about the size of the original DB as I have plenty of disk space.

Subject: reclaiming space
I have moved a couple hundred mailboxes from one Exchange server
to another in hopes of reclaiming some space on the first server. In all
so far I have moved about 120 gig of mailboxes to the other server but I
do not see that space coming back on the first server. I do run the
online maintenance of the databases that is built inside of the system
manager. I also get emails nightly on what was done. Below is one that I
got last night. I was under the impression that Exchange would clean
itself up after the moves and allow the database to shrink after it ran
the maintenance.
Do I have something set wrong or is my thinking wrong. If my
thinking is wrong do I need to do an offline defrag to get the space
back?

RE: reclaiming space
This has been tested pretty intensively recently and found to behave as expected. The only times I have seen ANY difference at all was on tiny workgroup servers with a couple of disk spindles, and quite large databases. Essentially we only get about 25MB/sec per stream from the backup API (per SG), so as long as your disks can hit that, NTFS defrag wont make any difference to online backups (it may reduce IOPS though). Online maintenance is also a mostly random operation, so that's unlikely to see any improvements. The user experience improvement is likely to be perceived, what was the actual drop in RPC Averaged Latency? The one caveat to the NTFS defrag is if the EDB file was severely fragmented beforehand, i.e., hundreds of thousands of fragments. This can cause high CPU for NTFS read and write operations which can affect IO. However, unless you doing something insane like storing other data on the same LUN's as your EDB it would be unusual to see such fragmentation.

RE: reclaiming space
Then; as I said, our experiences have been different. The largest server I used the product on was an Exchange 2000 server running a 14 disk external SCSI array that was split into two 6 spindle sets that were stripped then mirrored, or was it mirrored then stripped, don't recall and I don't think it makes much of a difference. The system handled 850 to 900 users split over 3 MDB's in one storage group. Mailboxes ranged from less than 100 Mbytes to over 5 Gigs. This may or may not fit your definition of a "small workgroup server with few spindles". After several days of 5 and 6 hour backups, I ran a 3rd party defragmentation tool (NOT that piece of tripe that comes with Windows) and saw my backup times drop about 30 minutes per run and my users stopped complaining about how "Email is slow" for about two weeks. I could give a flying spaghetti monster less if you want to continue the argument.

Is there any benefit to running an offline defrag after you have

other than regaining disk space? I recently migrated about half
of my
users (50GB) to another storage group (Exchange 2003 SP2) and

RE: reclaiming space
Hi William: Yes, it did. That along with the registry hack that changed the size of the block that Exchange used to expand the physical database. TL's were on a completely separate spindle set, but I didn't do anything with them, seeing as how they would be purged nightly anyway. :-) You should have heard the fight I had with my manager when I wanted to change the pagefile.sys from a variable size to Fixed and run a boot time defrag of the system file. I was sure he was thinking I was planning some magical ritual in the data center that would have spelled the end of the world. :-) But that was a long time ago in a land far far away. John H.

The largest server I used the product on was an Exchange 2000 server running a 14 disk external SCSI array that was split into two 6 spindle sets that were stripped then mirrored, or was it mirrored then stripped, don't recall and I don't think it makes much of a difference. The system handled 850 to 900 users split over 3 MDB's in one storage group. Mailboxes ranged from less than 100 Mbytes to over 5 Gigs. This may or may not fit your definition of a "small workgroup server with few spindles". After several days of 5 and 6 hour backups, I ran a 3rd party defragmentation tool (NOT that piece of tripe that comes with Windows) and saw my backup times drop about 30 minutes per run and my users stopped complaining about how "Email is slow" for about two weeks. I could give a flying spaghetti monster less if you want to continue the argument. I suppose we can agree to disagree on this, but let's stop calling each other vacuum headed idiots for wanting to run something like a defragmentation utility on the server. And I am not a horse, I don't even play one in SecondLife. John H.

Woodrow Wilson -Original Message- From: Neil Johnson [mailto:[EMAIL PROTECTED] Sent: Friday, March 28, 2008 1:26 PM To: MS-Exchange Admin Issues Subject: RE: reclaiming space This has been tested pretty intensively recently and found to behave as expected. The only times I have seen ANY difference at all was on tiny workgroup servers with a couple of disk spindles, and quite large databases. Essentially we only get about 25MB/sec per stream from the backup API (per SG), so as long as your disks can hit that, NTFS defrag wont make any difference to online backups (it may reduce IOPS though). Online maintenance is also a mostly random operation, so that's unlikely to see any improvements. The user experience improvement is likely to be perceived, what was the actual drop in RPC Averaged Latency? The one caveat to the NTFS defrag is if the EDB file was severely fragmented beforehand, i.e., hundreds of thousands of fragments. This can cause high CPU for NTFS read and write operations which can affect IO.
