Recently, I decided to remove all the heal optimisations I made to
- cluster.self-heal-window-size: 1024
- cluster.background-self-heal-count: 16
Just reset them to defaults.
Since then I've done several rolling reboots and a lot of test kills of
glusterfsd. Each time the volume heals have been prompt and fast, so I'm
going t assume my settings were part of the problem. Perhaps the large
heal windows size was repsonsible for the long delays before heal started?
