hidekazualexchadin: hi07:38
alexchadinhi hidekazu07:38
hidekazualexchadin: i want to discuss about zone migration strategy bp which i proposed few hours ago.07:39
hidekazualexchadin: https://blueprints.launchpad.net/watcher/+spec/zone-migration-strategy07:39
alexchadinhidekazu: let me see07:39
hidekazualexchadin:  bp has too many work items.07:39
alexchadinwhat zone migration do itself?07:41
alexchadinhidekazu: ^07:41
hidekazualexchadin: zone migration strategy choose instances or volumes to migrate, migrate them.07:42
alexchadinhidekazu: but our other strategies do the same (except of volumes)07:44
alexchadinhidekazu: they have goal to achieve (consolidation/balancing/temp reduce)07:45
alexchadinhidekazu: what goal would be right for zone migration strategy?07:45
hidekazualexchadin: precondition is that physical resources are classified by other system. one classification is targeted to maintenance, zone migration would migrate instances and volumes on the classification.07:50
hidekazualexchadin: so goal is that all instanes and volumes are migrated on the classification.07:51
alexchadinhidekazu: you speak about evacuation, when host is down and all the vms should be boot on the other hosts?07:53
hidekazualexchadin: no, zone migration is for planned maintenance. active vm should be live migration.07:55
hidekazualexchadin: even if planned maintenance, too many instances and volumes should be migrated automatically and efficiency. so watcher  comes in.07:57
*** thorst has joined #openstack-watcher07:57
alexchadinhidekazu: how will watcher know that planned maintenance started?07:58
hidekazualexchadin: since planned maintenance, operator creates zone migration audit first.07:59
hidekazualexchadin: after started, continuous audit periodically choose some instances or volumes by number of cpu or size(volume) or network usage etc.08:01
alexchadinhidekazu: how do you plan to use nova-scheduler?08:02
*** sanfern has joined #openstack-watcher08:03
hidekazualexchadin: precondition is that source hosts are all service disabled. so nova-scheduler choose some hosts which should be migrated.08:04
hidekazualexchadin: migration action in watcher is now live migration. so nova-scheduler is only applied to live migration.08:05
*** acabot has quit IRC08:06
alexchadinhidekazu: nova-scheduler don't use filters for live migration, only for cold08:06
*** efoley has joined #openstack-watcher08:11
hidekazualexchadin: live migration can be specified destination host. but it is possible not to specify destination host.08:12
*** acabot has joined #openstack-watcher08:13
hidekazualexchadin: destination host is optional when using live migration.08:13
*** efoley_ has joined #openstack-watcher08:14
hidekazualexchadin: should i write more detail in bp as above discussion?08:15
*** thorst has quit IRC08:17
alexchadinhidekazu: I accept this BP since some parts of it make sense to me, but you need to provide as much details as possible in spec08:17
*** efoley has quit IRC08:18
hidekazualexchadin: first i write spec, and then break down spec if needed. right?08:18
alexchadinhidekazu: please, take attention to use cases08:18
hidekazualexchadin: yes, there is use cases in spec section.08:19
alexchadinhidekazu: right, we will see if your spec should be split up08:19
hidekazualexchadin: thanks, i will write spec of the bp first.08:19
alexchadinhidekazu: great!08:20
