Re: Error with "Read Backup"

Thanks again for your assistance.

I set all tables to READ_BACKUP=0, but the resource usage didn't return to normal. I then restarted the cluster. While the first data node was restarting, the second one crashed. I then restarted both of them and the cluster seemed fine. Resource usage stayed high until I ran "analyze tables". Then resource usage dropped, but I don't know if it was because of the analyze command or just a coincidence. I then made a few tables READ_BACKUP=1. At the moment, ndbmtd is only using 17% of CPU. That is compared to 500% earlier.

Since CPU usage is low now, I'll leave NoOfFragmentLogParts alone for now.
