Description of problem: ========================= (A possible regression) When a brick is down the heal info of a disperse volume takes significantly longer time. for eg: without any heal pending or on a fresh setup, with all bricks up, the heal info response time for a 1x(4+2) volume is hardly 1 sec where as with one brick down the same setup takes 11 Sec and in one case where heal pending entries were there the heal info was hung(the re were hardly 10 entries on each brick) If I hit the hang again, will raise a seperate bug Version-Release number of selected component (if applicable): === 3.8.4-28 How reproducible: == always Steps to Reproduce: 1.create a 4+2 ecvolume and check heal info time (it will be hardly 1 sec) 2.kill one brick 3.check heal info time(takes about 11 sec)

COMMIT: https://review.gluster.org/17606 committed in master by Pranith Kumar Karampuri (pkarampu) ------ commit 630d3d8c8466228e1764c1c0962b9db40548fffb Author: Ashish Pandey <aspandey> Date: Thu Jun 22 17:06:40 2017 +0530 ec: Increase notification in all the cases Problem: "gluster v heal <volname> info" is taking long time to respond when a brick is down. RCA: Heal info command does virtual mount. EC wait for 10 seconds, before sending UP call to upper xlator, to get notification (DOWN or UP) from all the bricks. Currently, we are increasing ec->xl_notify_count based on the current status of the brick. So, if a DOWN event notification has come and brick is already down, we are not increasing ec->xl_notify_count in ec_handle_down. Solution: Handle DOWN even as notification irrespective of what is the current status of brick.
