splitting exchange edb's is larger in total than one single edb ???

I've got an exchange 2010 server, that the one and only main edb (500gb) crashed. I then moved all my mail to 4 x roughly 100gb edb's

The 500Gb edb was on a drive for the exchange, at the moment i have the edb's spread over two drives.
I have deleted the old 500gb edb.
I would like to move these 4 edb's onto one drive again.

My issue, is that, when it was one edb, it was 500gb, now i have 4. it's around 675gb. this is the actual edb, and does not include the e00.....files

Mailbox A - 100gb
Mailbox B - 118gb
Mailbox C - 318Gb
Mailbox F - 140gb
Total - 676gb

I cannot move mailbox c back to the exchange drive we have, as I don't have enough space. as we used to have 150gb spare and now find myself 25gb short.

I've run a check on whitespace and can confirm it mb's for 3 of the edb's and 8gb for mailbox c. So it's not that.

I'm unsure how this has happened and how to shrink it all.

All this work has been done in the last week. And can't be down to natural growth.

do you have separate mailbox quota limits for each edb you created?

If not, you can create two edb files with around 250 GB each in size may be on two new drives and then move your current 4 edb data to those two edb files

Keep only one edb file per drive

ASKER

But then how would you know if it would reduce to 500 in total and not stay at 675?
When you move mailboxes from these dbs to new dbs, white space will be reclaimed with great extent and even it will take less space than 500 GB

200-250 gb is Microsoft recommended edb size
I would agree with you, but as mentioned in my question. I did the below and there is no real massive white space to reclaim

I've run a check on whitespace and can confirm it mb's for 3 of the edb's and 8gb for mailbox c. So it's not that.
How did you figured out that
And any how you don't have any option apart from moving mailboxes from one db to another online
Offline defragmentation is is not an option as u need to dismount database for that
Mailbox move should free some good amount of space for breathing
I ran a powershell command that gives you whitespace value. All the other 3 mailboxs only had a few mb and mailbox edb has 8gb. Which isn't alot.

There isn't much white space, as I moved from the old 500gb edb but only a week ago.

I'm after a reason why my total edb space has raised 175gb just through moving mailboxs to newer edbs
PowerShell won't give you entire white space, it only gives you free space in database root tree

keep your DBs in multiples of 200-250 GB size on separate disks to avoid entire data loss if disk fails and keep them moving to new DBs to free white space.
Here is my suggestion, you need more disk space to perform the task you want to achieve. If these are SAN drive you can add more disk space or add new lun's, create new DB, move mailboxes and release old DB and lun space back. If you don't have option to increase disk space, you can create new server and split mailboxes to new and old server.
I'm not after more disk space. Just some one to tell me why I had a 500gb edb which I've migrated to 4 x edb files and it's now 675gb in total.
I don't understand why you have posted transition from 2010 to 2013. All I've done is create new edb files on the existing server (2010) and move mailboxs to it.
