Why are you getting confused?? .EDB is a database where exchange server stores the information store data ( or in simple words Emails).

Option 1:

Download emails of each user who belongs to the mailbox STORE which is heavy for you, by configuring outlook and downloading their emails to PST files.
Running ESEUTIL tool on exchange DB and do a defragmentation once every employees download thier emails from the server to local .PST files. This will reduce the DB size to the actual size.

Disadvantage with ESEUTIL:

During defragmentation Exchange Information store has to be OFFLINE.Some times due to inconsistancy in the DB defragmenatation can even fail.Time for Defragmenatation will be high ( if its 100 Gb then it may go till 10 hours and so )]

Option 2:

Download employees emails to .PST files. Create one more Mailbox Store and start moving the mailboxes to the new mailbox store. Point the Edb and Stm file of the new new mailbox store to a different location (not to the same folder where the EDB & STM files of the excisting mailbox store is locating)

Advantages : No down time required, No risk of DB corruption, Can do this activity online without any downtime, will have the actual mailbox size reflected, NO RISK INVOLVED.

Disadvantage: Need to close the mailbox which are getting moved, Co-ordination required between Exchange Admin and employee for movement.Note: Once you move all the mailboxes to the new mailbox then please go the same folder where the older mailbox store edb & stm files are stored and delete those.

Thanks & Regards

Adding a New Hard Drive to Linux using LVM

I did this on RHEL 5.5. You should have the new drive created and added to the machine before you start anything.First you need to fdisk the drive like any other drive in linux. One key step is that you need to change the type; option ?t? to ?8e? for lvm. root@itsme ~# fdisk /dev/sdc Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel. Changes will remain in memory only,until you decide to write them. After that, of course, the previous content won't be recoverable. The number of cylinders for this disk is set to 7832. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite) Command (m for help): n Command action e ex...
