CAUSE

The disk drive containing the transaction logs for the service (MDBDATA for the IS and DSADATA for the DS) has no available space to create another log file.

Back to the top

Using the Microsoft Exchange Performance Optimizer, move the transaction logs to another drive containing sufficient free disk space. The new drive should have enough free disk space for all the existing logs to be moved to that drive and then have enough free disk space for the service to startup.

MORE INFORMATION

The following events take place when the JET database engine detects and out of disk space condition on the log file drive:

The JET database engine refuses to take any more transactions from the Information Store service or Directory service.
The Information Store will rollback all uncommitted transactions (this is done with the use of the reserved log files RES1.LOG and RES2.LOG).
The Information Store shuts down gracefully, meaning all uncommitted transactions in the log files are flushed into the database and the databases are in a consistent state.

If log files are filling up your drive, you may want to find out whether they are being purged after backups. For more information on how to determine which log files can safely be deleted, click the following article number to view the article in the Microsoft Knowledge Base:
