EXCHSRVR taking to much space

we have exchange server with 4 storage groups and in the properties of each storage groups the system path location is pointing to D:\EXCHSRVR.

this folder is getting too big.

any idea why it's getting too big and how to free some space?

taking 98% of the disk
Check where the exchange database files are located. Mostly the .edb and .stm database files will be stored there, which are taking this much of spce.

you could defrag the databases offline

1. Dismount
Go into ESM and dismount your Exchange partitions. Drill down ESM > Servers > Your Server > First Storage Group. Right click on the Mailbox store, and click Dismount Store. Then right click on the Public Store, and click Dismount Store.

2. Defrag
Open up a command window (Start > Run > Cmd). Assuming your Exchange partition is located on your C: drive, type the following commands:
( do make sure you have a backup)

Step 1.  cd \Program Files\Exchsrvr\mdbdata
Step 2.  dir priv1* pub1*
Step 3.  ..\bin\eseutil /d pub1.edb
Step 4.  ..\bin\eseutil /d priv1.edb
Step 5.  dir priv1* pub1*

but it probably won't help you much
best is to get or another diskdrive or if you have space on another partition to move some exchange databases

You can move them in ESM, rightclicking on the store and (somewhere there, dont know it exactly out of my head) you can set a new path for the EDB files, it will then move them to the new location)

some mailbox stores have their edb and stm pointing there.
Check the log files.  In system manager you can find where the logs are being stored.  I had this problem on Exchange 2000.  You should also look into defraging the DB.  http://support.microsoft.com/kb/328804

Make sure that the temp log files are being removed after backups, there is an option for purging data after being written to DB.
Please do not defrag or move the files, make sure you should go through proper steps. You should be more careful for exchange databases. Before going for defrag (Offline Defrag), please check whether the total size of all the mailboxes in those mailbox stores are very much near to the size of the database files cosuming. You will come to know the approximate figure of the size of the white space from the difference between them. If the difference is not much do not go for defrag option.

Best option, is creating a new storage group and new stores in a different drive having much space available and safely move the mailboxes through ESM without affecting production. You can load balance between the new and old mailbox stores by number of users and size of the mailboxes. Then you can go for derag option of the old database to remove the whitespace with reference to kb http://support.microsoft.com/kb/328804 after dismounting the database.
Let me know for any issues.
Try PerfectDisk to defrag the DB.  Not only will it shrink it but exchange will run faster alltogether.
Before you do anything make sure your Exchange backup is working and purging the log files. The most common cause for disk filling up is due to the backup not purging the transaction logs and the logs filling up the disk.

is there any way to run an immediate OnLine defrag, instead of scheduling it.
I looked and could not find run immediatel.
You could set a custom schedule to run. But I don't think that will gain as much space as you are expecting. You really need to do an offline defrag.

logs and database are in 2 different drives.
the drive that has the database is getting almost filled up.
 where it says  system path location in the storage group properties if I change that to a different drive with more space, would this create a problem or reolve it?
would this create a new database or I have to move the existing one to the new drive?

By the way can someone tell me the difference between:

System Path Location under the General tab of the storage group properties.


Exchange Database & Straeamin database under the Database tab of the mailbox or public folder store?
The system path location specifies the location of the database system files: temp.edb and check point file(*.chk). The Exchange database specifies the exact location of Exchange database file for the store(*.edb) and Streaming database specifies the location of the Exchange streaming media database file(*.stm) for the store.

The system files should not take much space. Changing the system file path will not create new database. The database file *.edb should be taking more space. Dismount the store, move the file to a new drive and change the path of the database file in the ESM->mailbox store properties->Database.
You can also move the *.stm file in the same way if it is taking more space. Then mount the store.
