I have 2 identical mail servers in a cluster and both servers have DAOS enabled. Both servers have a user mail files on them for failover. One server now has 250 GB of free space and the other only has 76GB of free space. Why are the DAOS enabled databases not the same size of the 2 servers.
Subject: RE: DAOS disk usage on a cluster
DAOS maybe enabled on the server but is DAOS enabled on the mail databases?
Check the “DAOS State” tab in the “Files” section of Domino Administrator. IF it says N/A then the database property for DAOS has not been enabled.
You’ll want to confirm via the Admin client help the below command.
Preferably with the server down (so opened databases will not prevent the process from completing)run the following:
ncompact -c -daos on
You may also want to look at the database properties for LZ1 compression, data compression and design compression. Enabling them and compacting (prior) to enabling DAOS can benefit your overal storage.
See the link below for best practices.

DAOS is enabled and set to read/write for all of the databases. It just seems odd to me that the databases are different sizes on each of the servers
Subject: RE: DAOS is enabled
I’d compare the object counts on both servers and see how may attachments have been pulled out. And compare sizes.
If they differ maybe check the size settings on the DAOS tab on the server doc… make sure both servers are using same size. Also verify that the mail.box file(s) are transaction logging and that DAOS is enabled in thier db properties.
I’m new to DAOS, so I’m still learning all the parts of it. I’m out of ideas right now.
