glusterd will be run with "*.upgrade=on" argument after rpm installation. I think you can plugin your upgrade scripts with that option.

Hi All,

Need help in the gluster upgrade scenario, i.e information on upgrade 
scripts/hooks(might be in glusterd)

Tiering requirement is CTR Xlator database schema will change for performance 
again  http://review.gluster.org/#/c/13248/

So older version of gluster would need to migrate the database entries to the 
new database. I can provide with the script or code to do so, but need info on 
the upgrade hooks.

Regards,
Joe
