Exchange 2010 - unable to mount DB

Hi All,

My c drive of my server was full with log files. My assistant deleted the log files for and rebooted the server.

Now the DB won't mount.

What are my options for recovery?

Please help

your only option at this point is to either

1. Execute an ESEUTIL /P to get into a mountable state and then once mounted I would suggest that you create a new DB and move all users into that new DB since once a DB is repaired it is never the same.  NOTE: the /p will repair the DB by removing incomplete or damaged pages from the DB so you will experience SOME data loss, however assuming that the only issue is that the log files are missing the loss should be negligible.

2. Other option is to restore from latest backup, however depending on when the backup was I think this will cause more data loss than desired.

Check for last good backup :)

Run the below command and shared details
eseutil /mh "location of .edb"

- Rancy
Try soft recovery first
Run eseutil /mh and bring the check for dirty shutdown.....if yes..then bring it to clean shutdown mode.....

If not done, then go for hard recovery.......
when databases corrupt it's need log files for repair and you deleted log files if you have full backup you can recover it .

Log files should not be deleted - When an Exchange backup is taken then the log files will be cleared. If you have lots of log files it indicates that your Exchange Server is not being backed up

Is it possible some of the Exx.log files were deleted accidentally ?

Do you have a recent backup or shadow copy enabled ?

Step2 is where you need to move the logs
