Open Stack

Hi everyone working for Manila,

This is Vincent Hou from IBM. I am working on all the migration issues in 
Cinder.

I had one session for the Cinder migration issue in Vancouver and some of 
you folks attended it. The etherpad link is 
https://etherpad.openstack.org/p/volume-migration-improvement
Per the issue that we had better not let the user see the target volume 
during migration when issuing command "cinder list", we can add an 
additional flag into the volume table, for example, "hidden", into it. The 
default value is 0, meaning that it will display for "cinder list". For 
the target volume during migration. We can set it to 1, so the user will 
not be able to see it with the command "cinder list". I think it is a 
straightforward approach we can go with. I just sync up with you folks, so 
that we can have a consistent way to resolve this issue in both Cinder and 
Manila. I just need to make sure we are on the same page. Is this solution 
OK with you folks? Especially @Rodrigo Barbieri and @Erlon Cruz, etc.

Looking forward to hearing from you. Thanks.

Best wishes,
Vincent Hou (侯胜博)
