Gluster users - Sep 2012 - Downgrading OS while keeping files

Hi (again),

have four gluster (3.2.6) servers on which I want to downgrade the OS 
(fr CentOS-6 to CentOS-5). Want to keep the file system (with 
raid10/ext4 on the servers), and I contemplate the following method:

Keep all configuration files under /etc/glusterd and /etc/glusterfs from 
the current installation, and after downgrading the OS (where I don't 
touch the raids)  and installing gluster see to that these configuration 
files are identical to how they were before.

Will this bring up file system as it was before the downgrade? Or am I 
missing something here?

Thanks,

/jon

What if I create a gluster system consisting of a number of bricks (say 
4) like

Brick1: k01:/mnt/raid6
Brick2: k02:/mnt/raid6
Brick3: k03:/mnt/raid6
Brick4: k04:/mnt/raid6

and if the mount points on each brick contains files I want to 
"incorporate" into the gluster file system. How can this be achieved?

Thanks,

/jon
