Hi, The current add and remove brick commands aren't sufficient to support add/remove brick on tiered volumes.So the commands need minor changes like mentioning which tier we are doing the operation on. So in order to specify the tier on which we are performing the changes, I thought of using the following commands for add and remove brick
adding brick on tiered volume: gluster volume tier <volname> add-hot-brick/add-cold-brick <brick> ... <force> removing brick on tierd volume: gluster volume tier <volname> remove-hot-brick/remove-cold-brick <brick> ... <start|stop|status|commit|force> I have framed it this way because once we mention details about tiering these commands become specific to tier and the syntax that we follow for commands are gluster volume component <VOLNAME> ... So i have made sure that the keyword tier comes after volume. Need suggestions to make these commands better. Similarly once we support add/remove brick we will be having rebalance commands and the idea is to support rebalance separately for each tier. So once we will have to rebalance status to display for which we need rebalance commands specific to tier. so these are the commands we have thought of: gluster v tier <VOLNAME> hot-rebalance/cold-rebalance <start|stop|status> Need your comments regarding this. -- Regards, Hari. _______________________________________________ Gluster-devel mailing list Gluster-devel@gluster.org http://www.gluster.org/mailman/listinfo/gluster-devel
