Before you can re-mount any of the databases, you must free up some space on exchange 2010 purge transaction logs the transaction log drive. There are two basic rules to follow when freeing up space on a log drive: Do not delete log files outright. Move them to a different drive so that

you can get them back if they are needed. Do not remove all the log files, even if the databases have been shut down cleanly. Remove only log files that are older than the current checkpoint. This post will explain best practices for managing log drive disk space and tell you how to determine which log files you can safely move if your log drive does fill up.
Exchange 2010 Logs Filling Up
Why does this subject warrant a post? In looking over cases opened with Microsoft Product Support Services (PSS), we discovered that a surprising percentage of Exchange disaster recovery cases are triggered by an Exchange log drive filling up. The intuitive thing to do if a drive is full is to delete files to free up space. But that is exactly the wrong thing to do when it comes to Exchange transaction logs. The log files are critical to Exchange's recoverability. How do transaction log files work in Exchange? In brief, when an Exchange database starts ("mounts") it attaches itself to the transaction log files for the storage group to which the database belongs. Every change made to the database will be recorded in a log file before it is written to the database. Log files are each 5 megabytes in size, and they automatically "roll over" to a new log file when they fill up. Log files are numbered in sequence according to this naming scheme: EnnXXXXX.log Enn represents the log file prefix. The prefix is different for each set of log files on a server, and is usually E00, E01, E02 or E03 (because there can be up to four storage group

will describe preventive measures that should help you avoid running out of disk space and in addition I enable circular logging exchange 2003 will also describe possible remedies if this has (gasp) already happened. I find Exchange server to be a very complicated system and as in most complicated systems the most "trivial https://blogs.technet.microsoft.com/exchange/2004/05/12/how-to-recover-from-disk-full-on-an-exchange-log-drive/ things" may bring it to its knees. One of these "trivial things" is lack of disk space on the disk that holds the log files for a specific storage group. When the Information Store identifies lack of disk space for a storage group's logs it will dismount the stores inside the respective storage group. The last sentence I wrote may sound http://www.msexchange.org/articles-tutorials/exchange-server-2003/planning-architecture/Exchange-log-disk-full.html very calm yet when this happens on one of the Exchange servers you are responsible for you will be anything but calm. Once the stores in the storage group are dismounted, users are disconnected from their precious information (mail, calendars, contacts…) and they will come waving pitchforks… Before we delve into our main subjects I think it is important to understand the exact role that log files have. Describing the Exchange storage system A very oversimplified analysis of an Exchange server may state that that an Exchange server is nothing more then a database server that has some exotic extensions through which users can manipulate their data. This analysis (even though oversimplified) is not far from truth, and it emphasizes the importance of the database that stores the user's information on an Exchange server. Exchange server uses a database technology called ESE (Extensible Storage Engine), this database technology is based on the JET (Joint Engine Technology) database engine. The ESE engine employs several files upon which the database is built (I have only specified the ones that are relevant to o

My Exchange server crashed and I'm trying to mount the http://www.virtualhelp.me/windows/579-exchange-2010-error-unable-to-mount-database database, with no luck. This is the error that I get: --------------------------------------------------------Microsoft Exchange Error--------------------------------------------------------Failed to mount database 'Mailbox Database'.

A. You have a corrupted database or corrupted logs. Several tests need to be performed, to see what the issue is (this is log disk full an example for Exchange 2010, but it works for previous versions as well): Check and Repair the database 1. Check the database: eseutil /mh "C:\Program Files\Microsoft\Exchange Server\V14\Mailbox\Mailbox Database\Mailbox Database.edb" Look for the following in the output: State: Dirty Shutdown 1.a Since the database has not been properly shut down, it needs to be repaired. Make sure you make a backup of the database before attemting any kind of repairs To repair, run the following: eseutil /p "C:\Program Files\Microsoft\Exchange Server\V14\Mailbox\Mailbox Database\Mailbox Database.edb" 1.b Re-run the database check from 1.a and if all goes well, you should see this somewhere in the output: State: Clean Shutdown You can try mounting the database. If it mounts, you are good to go, if it doesn't you have to check the logs: Check and Repair the database logs 2. Check the exchange logs (don't forget to specify E00 - the starting sequence for the logs) eseutil /ml "C:\Program Files\Microsoft\Exchange Server\V14\Mailbox\Mailbox Database\E00" 2.a There will be a list of logs and depending on their state, you may get an error. (They should all say OK, if the logs are clean) Errors vary, but most likely it is a file corruption and needs a chkdsrestored an Exchange database, and now you are trying to mount it. To your surprise, you are getting an error similar to the following: Couldn't mount the database that you specified. Specified database: DB2; Errorcode: An Active Manager operation failed. Error: The database action failed. Error: An error occurred while trying to select a database copy for possible activation. Error: The database ‘DB2' was not mounted because errors occurred either while validating database copies for possible activation, or while attempting to activate another copy. Detailed error(s): An Active Manager operation failed. Error: Operation failed with message: MapiExceptionCallFailed: Unable to mount database. (hr=0x80004005, ec=-550) Before you can mount a database restored from a backup, it needs to be in a clean shutdown state. You can use the Eseutil tool to check whether a database is in a clean shutdown state – if it is not in a clean shutdown state you can perform a repair to get the database into consistency. Soft Recovery using Eseutil The first thing you want to do is verify that the database is in a dirty shutdown state. We can do this using the eseutil /mh command. For example: The output from the above command shows us that the database is dirty shutdown: We can also see from the output, under Log Required, the database is missing a transaction log. We can replay log files into the database (as long as they exist) to get the database into consistency. To do this, we use the following syntax with eseutil: eseutil /r /l /d
For example, my log file prefix is E02, and my database and logs are stored in G:\E_\Program Files\Microsoft\Exchange Server\V14\Mailbox\DAGDB1 . Here is a screen shot of the command: When this repair is complete, I can run the eseutil /mh command again to verify that the database is in a clean shut down state: At this point, I'll be able to mount the database. This will almos
