Re: MySQL Cluster data nodes fails with 7200: LCP fragment scan watchdog

Hi Mikael,

Thanks for your insight. I just encountered error 7200 myself while rebuilding a cluster (due to a different NDB issue I couldn't recover from). I got this error while trying to perform mass insertions into various NDB tables.

My development cluster includes two nodes, running: mysql-5.7.18 ndb-7.6.3.

You mention:
> If you have lots of disk data to write (presumably not since I saw no disk data configs in your config) it could cause this issue if the disk is very slow.

My development server does have slow hard drives... is there a configuration change I can make to prevent slow drives from causing error 7200?

Best regards,
