nttmmm... I know the problem...08:45
kota_that commit is probably one of what you need08:45
nttyes... But probably I can plan an update to liberty08:45
nttHave you experience with swift update?08:45
kota_ntt: yes but it is only in test environment08:46
nttwell.... I always test upgrade in a safe environment.... Actually in production I have 3 nodes with 3 zones and 1 region08:46
kota_I'm a developer so usually I do update/downgrade, deploying any commit to test the functionality.08:47
kota_ok08:47
kota_ntt: sounds great.08:47
nttthe evolution of my swift environment is really wonderful: started with one node whith all services: proxy, object, container and account. 1 node, 1 region, 1 zone. I used a san as backend with 4 disks of 5TB each08:48
nttThen I added 2 proxy nodes08:48
nttThen I added 2 zones08:48
nttnow it's time to remove the node on z1 and substitute it with a production node08:49
nttno data loss .... at the moment :)08:49
kota_great story :)08:50
nttactually it seems that cpu is a bit high on storage nodes.... I think it is related to object replicator and auditor .... interval are too close I think08:50

zaitcevbriancline's update to go/README.md says "First, you should have a working [SAIO][2] with no storage policies." This can't be entirely true, because I'm 100% certain that redbo and dfg have non-SAIO Hummingbird running. So... going a step further...23:24
zaitcevIf I have a cluster that has storage policies implemented, and I have a replication policy, maybe I can drop-in Hummingbird? I'm trying to remember what may happen if I do that.23:24
