Hi Atin,Thanks for your reply.Its urgent because this error is very rarely reproducible we have seen this 2 3 times in our system till now.We have delivery in near future so that we want it asap. Please try to review it internally.
I don't think your statements justified the reason of urgency as (a) you have mentioned it to be *rarely* reproducible and (b) I am still waiting for a real use case where glusterd will go through multiple restarts in a loop?

This patch needs to be thoroughly reviewed to ensure that it doesn't cause any regression given this touches on the core store management functionality of glusterd. AFAICT, we get into an empty info file only when volume set operation is executed and in parallel one of the glusterd instance in other nodes have been brought down and whole sequence of operation happens in a loop. The test case through which you can get into this situation is not something you'd hit in production. Please help me to understand the urgency here.Also in one of the earlier thread, I did mention the workaround of this issue back to Xin through http://lists.gluster.org/pipermail/gluster-users/2017-Januar y/029600.html "If you end up in having a 0 byte info file you'd need to copy the same info file from other node and put it there and restart glusterd"--I have found one of the existing case is there and also solution patch is available but the status of that patch in "cannot merge". Also the "info" file is empty and "info.tmp" file present in "lib/glusterd/vol" directory.please let me know what is the plan of community to provide the solution of this problem and in which version.
