The codebase that this XAPI patch is based on is a bit old (5.5.0; George), but I think some form of it still exists in the latest codebase.
What we're seeing is that if the master host goes away during slave RRD processing, it will prevent the slave XAPI from transitioning to master. The patch adds a try-lock in the RRD backup so if the lock is still held, the backup is skipped. I'm wondering if this is a safe change (at least for 5.5.0), and if anyone has ever run into this before? (An unreliable way of generating the situation is to pull the management link during a migration.) Thanks for the help, -- Ted M Lin
