I'm not sure if you can increase (and later decrease) the replica count without stopping the volume.
Have you checked that as an option ?

Hi,
I am looking to replace a brick in a replicated volume with arbiter (2+1 bricks).
Judging from this page: https://docs.gluster.org/en/latest/Administrator%20Guide/Managing%20Volumes/#replace-brick
it seems that the procedure is: simulate a brick failure, then add a replacement brick.
Is that the only way to do it? Isn't there a way to migrate the data on the fly without running on reduced redundancy during the migration, like pvmove exists for LVM?
Thanks,
Stefan
