[Gluster-users] On making ctime generator enabled by default in stack

All, There is a patch [1] from Kotresh, which makes ctime generator as default in stack. Currently ctime generator is being recommended only for usecases where ctime is important (like for Elasticsearch). However, a reliable (c)(m)time can fix many consistency issues within glusterfs stack too.

Normally client logs will give a clue on why the disconnections are happening (ping-timeout, wrong port etc). Can you look into client logs to figure out what's happening? If you can't find anything, can you send across client logs? On Wed, Aug 29, 2018 at 6:11 PM, Richard Neuboeck wrote: > Hi
