BIG Problem with Exchange 2007 Mailbox Database
Posted on 2011-02-22
We have and Exchange 2007 server running on Windows Server 2003 R2 within a virtual enviroment (VMWare).
Recently BackupExec started failing to backup the store due to connectivity issues, however our clients could still connect without issue-sending and receiving messages.
The first storage group mailbox database is 99Gb.
I attempted a Microsoft Backup of the store which failed again due to a read error.
Prior to running ESEUTIL I really want a backup/copy of the database so I resorted to unmounting the database and undertaking a manual copy. With 5 minutes of the copy to go, this failed with the following error in the Event Viewer:
Event Type: Error
Event Source: symmpi
Event Category: None
Event ID: 9
The device, \Device\Scsi\symmpi1, did not respond within the timeout period.
Worrying that there was a problem with the disk a ran a Windows Disk Check, this reported no errors.
I then decided to clone the machine in the hope to have a backup prior to running ESEUTIL. Sadly vSphere failed with the following error:
Error caused by file [Shared_DataStore1]Hermes/Hermes_1.vm-dk
No further detail was provided.
The server is back up and running again without any error and is receiving messages. Obviously though there is something deeply wrong.
Any ideas as to how I could get a backup of the system in this cenario????
