[Gluster-users] Arbiter and Hot Tier

[Walter Deignan]

I've been googling this to no avail so apologies if this is explained 
somewhere I missed.

Is there a known incompatibility between using arbiters and hot tiering?

Experience on 3.9

Original volume - replica 3 arbiter 1
Attach replica 2 arbiter 1 hot tier - failure
Attach replica 3 hot tier - success

Experience on 3.10

Original volume - replica 3 arbiter 1
Attach replica 2 arbiter 1 hot tier - failure
Attach replica 3 hot tier - failure
Attach hot tier without specifying replica - success but comes in as a 
distributed tier which I would assume totally negates the point of having 
a replicated cold tier?

The specific error message I get is "volume attach-tier: failed: 
Increasing replica count for arbiter volumes is not supported."
