Hi all,

I have distributed replicated set with 2 servers (replicas) and am
trying to add another set of replicas: 1 x (1x1) => 2 x (1x1)

I have about 23G of data which I copy onto the first replica, check
everything and then add the other set of replicas and eventually
rebalance fix-layout, migrate-data.

Now on

Gluster v3.2.5 this took about 30 mins (to rebalance + migrate-data)

on

Gluster v3.4.2 this has been running for almost 4 hours and it's still
not finished


As I may have to do this in production, where the amount of data is
significantly larger than 23G, I'm looking at about three weeks of wait
to rebalance :)

Now my question is if this is as it's meant to be? I can see that v3.4.2
gives me more info about the rebalance process etc, but that surely
cannot justify the enormous time difference.

Is this normal/expected behaviour? If so I will have to stick with the
v3.2.5 as it seems way quicker.

Please, let me know if there is any 'well known' option/way/secret to
speed the rebalance up on v3.4.2.


thanks
