Would I be correct in this thinking?
2 servers as data nodes, multiple clients doing afr client side. This
is a new setup where server1 has 100 gigs of data and server2 has
empty directory.
So by doing afr client side, does the client have to read and transfer
data FROM server1, and then copy it

Could someone publish a example server-side afr setup (perhaps on the
wiki) just to see how the server and client vols hang together.

You have made a very good point.

So in my case where i have one directory with existing data and
another that is empty, should i set the trusted version to 1 on the
pre existing data and 3 on the empty directory? Or am I totally
missing what this does?
I agree starting with a clean slate is much easier/cleaner. But when

I think a little documentation there would be fantastic. I am also starting
with a full set of files that cannot be easily copied (a shared root... It
kind of has to be there already, by definition!).
Personally I was in the dark about all this until recent threads started
shedding a little light
Hope this helps if you are in doubt about what is higher value for attribute

Actually its an interesting doubt. as rank 1 is higher than rank 2 :p never

I think I accidentally butchered this thread because this was actually
a question on client versus server side afr, not setting up with pre
existing data...
HOWEVER.
I just had success. This time i tried with a TEST directory rather
than live data... /genius
Server1
/mnt/raid/gfs - contains 4 fo
It is quite simple to set it up.
on server1:
find /mnt/raid/gfs -exec setfattr -n trusted.glusterfs.version -v 2 {} \;
Here "2" is a number greater than "1" which is the version of the attribute-less
file. It is set on both file and directories. There is no need to set the
trusted.glusterfs.creat

Ok updated the wiki, and i took "There is no need to set the
trusted.glusterfs.createtime xattr." to mean there is no reason to
include that in the tutorial, so I only included removing the
trusted.glusterfs.version xattr.
