KP, Atin,
Currently in tiered volumes, we attach a tier and then start the rebalance
daemon in separate steps.
The problem here is if someone does readdir on the mount point before
starting the daemon, they won't see all of the directories. We have not yet
done fix-layout to make all directories live on all bricks.
What I need to do is combine those two commands into a single one.
What I am thinking is, at the cli level, we would first send the attach
command, and if it returns successfully, send the tier start command.
The current volume status (not rebalance status) actually issues
multiple RPCs from CLI, first it gets the volume list from glusterd and
in issues subsequent RPCs for each volume. I guess you can have a look
at that implementation if you find this challenging. As far as design
goes, I don't see that should be a problem, but in that case are we
going to disable the CLI interface for tier start? Does an admin need to
trigger tier start explicitly in any particular case?

Do you think it is ok to do this at the cli level (I hope my description
makes sense)
If not, do you see a better way? We can discuss if necessary..
Thanks,
Dan
