Adding an additional Exchange 2010 Mailbox database

I currently have exchange 2010 (Version 14.3 (Build 123.4), all roles on one server with one mailbox database and one public folder database.  I recently created an additional mailbox database.  Shortly after that database was mounted, mail delivery stopped to users (all users' mailboxes are still on the original mailbox database).  As soon as I unmounted the new mailbox database mail delivery resumed.  Is this normal?  If so what additional steps need to be taken to add an additional mailbox database without interrupting mail delivery to existing users?

Thanks!

Have you taken a look at your disk space? Make sure you have adequate resources.  You may not have enough resources for both.  Also take a look at your event viewer for errors.


Are your logs and .edb in separate drives?

Thanks for the response!  This was primitive move to ensure I do not run out of disk space as I only have 30 GB of free space on drive that houses the original mailbox database.  I have a new separate drive for the new mailbox database.  In addition the logs are on a separate drive which has plenty of space.
Try running  this  switch.   It will mount all databases on your server. Im not sure where your located but if its after hours then dismount your Active Database so you have both Databases Dismounted and then run the cmdlet below.

Get-MailboxDatabase -Server SERVERNAME | Mount-Database -Confirm:$False

Then Run Get-MailboxDatabaseCopyStatus  to see if both DB's are Mounted
