hi,
So far default quorum for 2-way replication is 'none' (i.e.
files/directories may go into split-brain) and for 3-way replication and
arbiter based replication it is 'auto' (files/directories won't go into
split-brain). There are requests to make default as 'auto' for 2-way
replication

HI Pranith,
Thanks for starting this mail thread.
Looking from a user perspective most important is to get a "good copy"
of data. I agree that people use replication for HA but having stale
data with HA will not have any value.
So I will suggest to make auto quorum as default configuration even

I do not think a quorum feature does a fair job in a 2 way replication. The
minimum criteria to use quorum is 3 and it does not make any sense to me to
turn it on by default for 2 way replication especially when HA is not
achieved if the 1st brick the pair goes down.
BTW, whats the history behind

"Availability" is a tricky word. Does it mean access to data now, or
later despite failure?

That is the point. There is an illusion of choice between Data integrity
