<br><font size=3>Okay, just tried it in 3.9 Even though attaching
a non arbiter volume (say a replica-2 ) as hot-tier is succeeding at the
CLI level, the brick volfiles seem to be generated incorrectly (I see that
the arbiter translator is getting loaded in one of the replica-2 bricks
too, which is incorrect). I'd recommend not to use arbiter for tiering
irrespective of hot or cold tier.<br>

I was tripped up by the change in apparent support for the cold tier between
3.9 and 3.10. But maybe that was just a fixed oversight which never should
have worked in the first place?</font><font size=3> <br>

Hi Walter,<br>
Yes, arbiter volumes are currently not supported with tiering.<br>

Is there a known incompatibility between using arbiters and hot tiering?</font><font size=3>

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?</font><font size=3> </font><font size=3 face="Arial"><br>
<br>
The specific error message I get is "volume attach-tier: failed: Increasing
replica count for arbiter volumes is not supported."</font><font size=3>
