Exch 2010 DB with 3 damaged trans logs - can I dismount then remount without issue?
Hi Experts.
I have an Exchange 2010 box with multiple mounted databases that is running ok except I can't backup a certain DB because the Backup in Progress flag is stuck on.
I need to restart the Info Store Service to clear this flag but cannot right now because the DB in question was on a drive that was filling up so I moved the translogs to another server and freed up the space I needed. At the weekend I moved a big production file to another drive and have now moved the trans logs back to the Exchange box. There's now plenty of space but it's being eaten up by trans logs as expected.
Before I restart the Info Store Service I want to flush these trans logs by enabling then disabling circular logging, dismounting and remounting the store accordingly.
eseutil /ml shows all the logs are present but 3 are damaged.
If I dismount the DB with the circular logging enabled will the damaged logs be a problem?
Thanks.
Paul.

Thanks Sembee, bad news is the DB is 1tb big! I can't wait too long for the repair to work as the server is in production and my experience is repair takes about 1gb per hour.
Any clever work arounds?

If the database is mounted then the only other option is to move all users to new database/s so you can just drop that one.
This is the primary reason why having large databases is a bad idea.

Isn't there a trick where I delete the CHK file and then dismount?
No idea - it isn't something I have ever done.

The only option you are going to have is to remove all of the logs, then stop the store and repair the database. Once done, you should then be able to restart the store and mount the database. I would then recommend that the database is replaced, by moving all mailboxes to a new database and the damaged one dropped.
