Information Store cache flush did not complete


When I attempt to failover a CMS in my Exchange 2007 SP2 SCC Active/Active/Passive cluster, it says it fails due to the "Checkpoint depth at start was 20 and at end was 17". However, the CMS does move to the passive node.

I also see this event id 113 in Application log:

Information Store cache flush before moving clustered mailbox server 'CMS2' did not complete. Data: Storage group Server\SG: checkpoint depth start was 20 and end was 17

The databases do seem to mount ok.

Is this something to worry about? Have I experienced any data loss? I'm not sure what exactly is going on here, and why is this an Informational ID only, sure it should be something more critical?

This happens whether I use Powershell or Exchange Management Console.

OS is Windows 2008 Server.

There is no issue. Event ID 113 is only information given in the logs. MS made new improvent in Exchange 2007, so don't need to worry. You can read the below article, which will clear your doubt.

Thanks, but what does it actually mean? What;s going on?

I will try to explain you in my words, but request you to read the article.

When administrator uses the Move-ClusteredMailboxServer command, in SCC failover takes nearly 5 mins and sametime database cache flushing was going on in the background, this is called opportunistic flush which allows client to be connected with the Exchange server, in order to avoid any downtime for the user. During failover process below two events are triggered in the logs

9868 logged two times. This tells, what is the status for flush operation going on.
113 it tells you what is the replications status.

Hope this clears your doubt.
