tab__What would be notation for swift-ring-builder command, when one is trying to use erasure coding type of policy, so what would be these commands when using for example ec 10/4 - swift-ring-builder account.builder create x x x, swift-ring-builder container.builder create x x x , swift-ring-builder object.builder create x x x?07:14

acolestab__: the account and container rings are unaffected by choice of erasure coding, the object ring replica count must equal the sum of EC data and parity fragments...08:46
acolesso in you rexample something like swift-ring-builder object.builder create 10 14 108:48

openstackgerritEran Rom proposed openstack/swift-specs: New middleware for Openstack Swift allowing to dynamically add compute functions along the pipeline, without the need to epxlicitly add new middleware.

tab__acoles: i have gone through saio example for erasure codes. Since in this example we are dealing with EC 4/2 i need to create 8 devices. So in case when I would have EC 6/2 situation, would 8 devices would still be ok? In case 10/4 that would mean that I need to robustly save data at least 10 devices?10:39

hurricanerixGood morning13:26
*** G________ has joined #openstack-swift13:38
acolestab__: you may get a better answer from peluse when he's around, but the EC total fragment roughly corresponds to 'replicas' so ideally you want at least as many devices as your total fragment count for your EC policy i.e. 10/4 -> 14 devices, but better would be to have >14 devices so there are some non-overlapping handoffs13:38

redboWe won't need it probably for a week or so.  We need to clear out our current pull requests in github and figure out how the import paths and build stuff is going to look.23:00

notmynameredbo: what do you want to call it?23:01
notmynamethe branch23:01
redbohummingbird or go.  If some other project has a "go" feature branch, doesn't that make it do weird stuff?23:02
notmynameyeah, in this case it should be unique to us. also, it has to start with "feature/". so how about "feature/hummingbird"?23:03
redboworks for me!23:03
