I wonder if anyone can shed some light on a issue we came across over the weekend, we have a exchange 2010 DAG and we noticed 3 databases (same DBs) were showing as:
Failed and Suspended
When we tried to mount he DB online we kept on receveing an error about JET_errDiskIO...............I've never seen this myself but after logging a case with microsoft and trying to recover\repair the DB they were unsuccessful.
The DB in question is about 1.2Tb in size - running the eseutil reports back as dirty shutdown and unable to restore.
We have managed to restore the DB from backup and run eseutil which reported back clean shutdown which has enabled us to extract the data from the EDB.
What I want to know is are there any limits on databases, is 1.2Tb big?
