Dismounting database in Exchange 2010 Cluster
Posted on 2012-08-30
We upgraded to Exchange 2010 from 2003 about a year ago. On numerous occasions, we ran out of disk space in our 2003 setup because of the transaction logs not being truncated properly. We had enabled circular logging in the 2003 environment so when we upgraded to our 2010 environment, we kept circular logging enabled.
We now have a good backup solution in place where the logs should be backed up and truncated appropriately so I'd like to disable the circular logging so I can actually setup an incremental backup.
I've seen that in order to do that, the database will need to be dismounted and then remounted. That seems pretty easy only we're in a cluster environment. We have 2 nodes in an active/passive setup with load balancing. Whenever I reboot the servers, I always manually switchover the server so I'm rebooting the passive node.
If I dismount the database, is that going to harm the cluster setup or possibly corrupt data?
If I take one of the servers offline, then I only have the one copy of the database, but again will that corrupt data if I dismount the database?
