Comment 12 Ambarish 2017-07-22 15:29:02 UTC

Verified on glusterfs-3.8.4-35.

[root@gqas003 ~]# gluster v set help|grep "cluster.brick"
Option: cluster.brick-multiplex
[root@gqas003 ~]# 

[root@gqas003 ~]# gluster v set help|grep "multiplex"
Option: cluster.brick-multiplex



Option: cluster.max-bricks-per-process
Default Value: 0
Description: This option can be used to limit the number of brick instances per brick process when brick-multiplexing is enabled. If not explicitly set, this tunable is set to 0 which denotes that brick-multiplexing can happen without any limit on the number of bricks per process. Also this option can't be set when the brick-multiplexing feature is disabled.


Option: cluster.brick-multiplex
Default Value: off
Description: This global option can be used to enable/disable brick multiplexing. Brick multiplexing ensures that compatible brick instances can share one single brick process.
