Hi, we have an Exhange 2010 environment, running DAG for 4 x databases
ALL EDB files on the D Drive of the server, and ALL Log files on the L drive.
We are getting errors in the Microsoft-Exchange-Troubleshooters/Operational Logs in the Event Viewer every hour
Event 5402
The database space troubleshooter detected insufficient space on volume D: for database xxxxxxxx Database. Provisioning for this database has been disabled. Database is under 25% free space.
Followed by Event 5700
The database space troubleshooter finished on volume D: for database xxxxxxxx Database. The database is over the expected threshold and continues to grow. Manual intervention is required.
EDB free space (drive space + free space): 94.07 GB
Percent EDB free space (drive space + free space): 21.38%
Log drive free space: 24.30 GB
Percent log drive free space: 41.19%

Information
As you can see, the event 5700 shows it has found EDB free space of 94.07Gb
the event says that there should be 25% available space for growth. So far so good.
BUT
The physical size of the EDB file on the D Drive is 66Gb
Therefore, 25% available space means that only 16-17Gb free space is required. We have 94Gb free, which is much more than 25%.
Why are we getting this error? Am i missing something, or perhaps misunderstanding the requirement here?
Kind Regards,
Carl
