We have an Exchange 2007 (Enterprise Edition) CCR cluster running on Windows 2008 server.  A database has dismounted giving Event ID 428 : The database engine is rejecting update operations due to low free disk space on the log disk. However, there is 1GB free on the log file mount point.

Can you guys help ?

Thank you

    Because mount points were used for the log file, this pointed to the mount point area which had 1GB free.  Looking at computer management .. disk management showed no space left!

    thanks !
