There is an arbiter feature for replica 3 volumes

being released in glusterfs 3.7 which would prevent files from going
into split-brains, you could try that out. If the writes can cause a
split-brain, it is failed with an ENOTCONN to the application.

Seems to be broken, because files are also stored on the 3rd brick, even
when using "replica 3 arbiter 1".

Zero byte files should be present inside the 3rd brick for maintaining afr's metadata. Do you happen to see files of similar size & consuming same disk space in the 3rd brick as in the first and second bricks?


Also, I don't see the .meta dir inside the mount point.

You will not be able to see .meta but should be able to change directory to .meta from the mount point. Please let us know if that is not the case.

Thanks,
Vijay
