Hi,
First of all , following command is not for disperse volume -
gluster volume heal elastic-volume info split-brain
This is applicable for replicate volumes only.
Could you please let us know what exactly do you want to test?
If you want to test disperse volume against failure of bricks or servers, you can kill some of the brick process.
Maximum redundant number of brick process. In 4+2, 2 is the redundancy count.
After killing two brick process, by using kill command, you can write some data on volume and the do force start of the volume.
gluster v <volname> start force
This will start all the killed brick processes also. At the end you can see tha heal should be done by self heal daemon and volume should become healthy again.

Subject: [Gluster-users] healing of disperse volume
Hi all, I'm pretty new to glusterfs, I managed to setup a dispersed
volume (4+2) using the release 6.1 from centos repository.. Is it a stable release?
Then I forced the volume stop when the application were writing on the
mount point.. getting a wanted inconsistent state, I'm
wondering what are the best practice to solve this kinds of
situation...I just found a detailed explanation about how to solve
splitting-head state of replicated volume at
https://docs.gluster.org/en/latest/Troubleshooting/resolving-splitbrain/
but it seems to be not applicable to the disperse volume type.
Do I miss to read some important piece of documentation? Please point
me to some reference.
Here's some command detail:
