[Gluster-users] Why oh why does gluster delay?
All, I am seeing it VERY consistently that when I do a 'gluster peer status' or 'gluster pool list', the system 'hangs' for up to 1 minute before spitting back results. I have 10 nodes all on the same network and currently ZERO volumes or bricks configured. Just trying to get good performance for the cluster to be talking to itself.... What is gluster doing that takes so long to respond? Seems there may be a more efficient way of doing it, whatever it is...

Until and unless it takes time to communicate back to CLI because of a poor N/W, I don't see any reason why would it take such a long time. Can you run glusterd with debug log enabled and share the *glusterd.log file with us? ~Atin> > > > I have 10 nodes all on the same network and currently ZERO volumes or > bricks configured.
