+++ This bug was initially created as a clone of Bug #1498570 +++ +++ This bug was initially created as a clone of Bug #1487495 +++ Description of problem: The option "performance.client-io-threads on" is needed in some scenarios where the fuse thread becomes a bottleneck. But this option seems to be disabled for replicated volumes i.e. setting the option on via the "gluster v set ..." command has no effect. It is fine to set the option to off by default for replicated volumes. But we need the option of turning it on in scenarios where we see that the fuse thread is bottlenecked.

COMMIT: https://review.gluster.org/18452 committed in release-3.12 by jiffin tony Thottan (jthottan) ------ commit 47604fad4c2a3951077e41e0c007ceb979bb2c24 Author: Ravishankar N <ravishankar> Date: Mon Oct 9 17:46:16 2017 +0530 glusterd: fix client io-threads option for replicate volumes Backport of https://review.gluster.org/#/c/18430/ Problem: Commit ff075a3d6f9b142911d25c27fd209838782bfff0 disabled loading client-io-threads for replicate volumes (it was set to on by default in commit e068c1997314046658dd502e9118dab32decf879) due to performance issues but in doing so, inadvertently failed to load the xlator even if the user explicitly enabled the option using the volume set command. This was despite returning returning sucess for the volume set. Fix: Modify the check in perfxl_option_handler() and add checks in volume create/add-brick/remove-brick code paths, tying it all to GD_OP_VERSION_3_12_2.
