I meant what are you using gluster for? VM workload or image/video file
creation or lots of small files etc etc.
1) We use glusterfs for general purpose, no limit to image/video file
creation or small files etc.
Is it replica 3 or replica 2 or arbiter or is it EC volume?
I use replica 2 on my test.
But in the real world, "we have deployed more than 100 glusterfs nodes in producion(20 nodes for the biggest single cluster)" per Liu Yuan. Replica 2/3, or EC are optional.
Please don't mind me asking so many details. I am delighted to see you guys
You are always welcome!
active in the community because I have seen Xiubo Li's work on tcmu-runner
who is also from chinamobile and his work is pretty good :-).
Yeah, i would be very pleasant to convey your praise. :)
2) We just want a low performance affect way to calculate each brick's
iops/bandwidth for the upper layer management app. BTW, is there any other
way to get iops/bandwith for each brick besides profile?
At the moment we have these stats using profile commands. As per Facebook
patches they enable json capture of io-stats on their volumes and measure
these. They have it enabled always. If that is not enough for you, then we
I think you mean FB guys gather data based on io-stats with profile always on, am i right?
BTW, are these patches open to everyone? so i can dig into it.
Yes, they do. The patches I gave earlier provide the facility to this in io-stats. Do let us know if you have any doubts.
should probably look at enhancing things. Do send patches if you think
something would make things better :-).
