[Gluster-users] Gluster 3.7.4 client to 3.4.2 server

[Wade Fitzpatrick]

I am trying to migrate away from our old server to a cluster of 3.7.4 
servers but I need to modify ~100 clients and sync the contents between 
the old and new servers at the same time.

I have tried applying the workaround mentioned in
http://www.gluster.org/pipermail/gluster-devel/2015-August/046361.html
but I am unable to get the newer client to successfully connect to the 
older server.

# gluster volume info

Volume Name: static
Type: Distribute
Volume ID: 3396ab28-f660-4853-817b-7cc1be6649a3
Status: Started
Number of Bricks: 1
Transport-type: tcp
Bricks:
Brick1: master:/data/static
Options Reconfigured:
auth.allow: 10.36.*,10.3.*
server.allow-insecure: on

# gluster volume set static client.bind-insecure off
volume set: failed: option : client.bind-insecure does not exist
Did you mean client.ssl?

# glusterfs --version
glusterfs 3.4.2 built on Jan 14 2014 18:05:35


and on the client:

Is there any way to make this work or should I stop trying? For the 
record, yes, the older client can access the newer servers.
