[Gluster-users] Replace brick 3.4.2 with 3.6.2?

[aytac zeren]

Hi John,

3.6.2 is a major release and introduces some new features in cluster wide
concept. Additionally it is not stable yet. The best way of doing it would
be establishing another 3.6.2 cluster, accessing 3.4.0 cluster via nfs or
native client, and copying content to 3.6.2 cluster gradually. While your
volume size decreases on 3.4.0 cluster, you can unmount 3.4.0 members from
cluster, upgrade them and add 3.6.2 trusted pool with brick. Please be
careful while doing this operation, as number of nodes in your cluster
should be reliable with your cluster design. (Stripped, Replicated,
Distributed or a combination of them).

Notice: I don't take any responsibility on the actions you have undertaken
with regards to my recommendations, as my recommendations are general and
does not take your archtiectural design into consideration.
