Hi,
I'm testing reliability of ceph recently, and I have met the flapping problem.
I have 2 replications, and cut off the cluster network ,now flapping can not stop,I have wait more than 30min, but status of osds are still not stable;
I want to know about when monitor recv reports from osds ,how it can mark one osd down?
(reports && reporter && grace) need to satisfied some conditions, how to calculate the grace?
and how long will the flapping stop?Does the flapping must be stopped by configure,such as configure an osd lost?
Can someone help me ?
Thanks~
