Lala, > Gluster 3.4 server bits with 3.6 client bits should work fine. > Have you tested this configuration? iic, the 'AFR' module ( replication) introduced its 'Version 2' implementation in 3.6 which is not compatible with its older version. The GlusterFS 3.4 & 3.5 versions are shipped with "AFR V1" , so I really doubt the mentioned configuration will work perfectly. AFR guys can confirm though. --Humble On Fri, Feb 6, 2015 at 7:01 PM, Lalatendu Mohanty <lmohanty at redhat.com> wrote: > On 02/06/2015 08:11 AM, Humble Devassy Chirammal wrote: > > On 02/05/2015 11:56 PM, Nux! wrote: > >> Thanks for sharing. >> Any idea if 3.6.2 still is compatible with v3.4 servers? >> > > >You mean 3.6.2 client bits with v3.4 servers? yes, it should work fine. > > > afacit, this will *not* work and its *not* supported. > > > > Humble, > > Gluster 3.4 server bits with 3.6 client bits should work fine. > > But I think the reserve (i.e. 3.6 server bits with older client bits) are > not compatible because of below issues > > - Older clients can not mount the newly created volume on 3.6 .
