[Gluster-devel] Upgrade planning

[Martin Fick]

I am considering building several clients which will potentially each mount 
shares from different servers.  Are there any organizational steps that I can 
take to plan for potentially non uniform server upgrades and incompatible 
glusterfs protocols?  

In other words, suppose I have client foo which mounts two shares, one from 
server A and one from B.  These shares are not connected in any way, they will 
simply get mounted each on separate mount points.  The only thing shared is the 
client glusterfs executable that mounts them.  If servers A & B and client foo 
are on glusterfs version X, is there a way that I can upgrade server B to an 
incompatible (to version X) version Y and still be able to mount shares from A 
& B on client foo?

Thanks,

-Martin
