After updating one of my Media Agents to service pack 22.27 this morning, Commvault decides it needed to reconstruct the DDB on that MA.  How can I tell what instigated/initiated the rebuild?

Hey @nerdgirl (love the name, btw)!

We should have some detail in SIDBEngine.log, though if I had to give the most likely reason, I’d say the dedupe engine was not completely ready to shutdown.

Did you confirm all operations were completed?

The link above isn’t long, but details what could happen if you don’t let everything finish.
