[Gluster-users] [CentOS 6] Upgrade to the glusterfs version in base or in glusterfs-epel

[Diep Pham Van]

Hi,
I'm using glusterfs version 3.4.0 from gluster-epel[1].
Recently, I find out that there's a glusterfs version in base repo
(3.4.0.36rhs).

So, is it recommend to use that version instead of gluster-epel version?
If yes, is there a guide to make the switch with no downtime?
When run yum update glusterfs, I got the following error[2].
I found a guide[3]:

> placed in the right fashion for redundancy, have no data to be
> self-healed and feel adventurous, you can perform a rolling upgrade
> through the following procedure:
Whey I must feel adventurous to use this method? What is the risk here?
