rds free disk space matrix

Question

Hi All,
Under cloudwatch matrix FreeStorageSpace for few RDS instances shows more GB compare to actual allocated. 
E.g. : 
Actual allocated space : 100 GB 
FreeStorageSpace : 103 GB

while for other RDS instances it was referring properly i.e. FreeStorageSpace less then actual allocated space.

Please advise .

Regards,
Nikhil Shah

Answer

Hi,

I see your problem mentioned above. It is impossible for FreeStorageSpace to be more than the allocated space. It is always the same or less.

You might needs to get those affected resources checked out by AWS Premium Support for further investigation.
