openstackgerritMerged openstack/swift master: Add more tests around ObjectExpirer.round_robin_order  https://review.openstack.org/54710001:11
thurloattimburke: looking at that now. there's a high liklihood of them being different. also looking into the configs and making sure they're proper between old and new proxies01:11
thurloathttps://hastebin.com/imezazihal.md01:11
thurloatactually, had that wrong. current v. uses keystonemiddleware not keystoneclient for the auth_token filter factory. version is keystonemiddleware==4.17.001:14
kota_good morning01:27
kota_timburke: even S3_ACL = False in the conf, the basic APIs except ACL should run successfully in swift301:28
kota_timburke: thx for follow up and rebasing on m_kazuhiro's work!01:29

DHEif I had a multi-region cluster, say 3 regions and a replica count of 3 and ensuring partitions in each region.... if I have a drive or node failure, can I count on (or force there to be) a hand-off in the same region as the failure will be used?02:18
claygi think in practice it would work basically the opposite of that acctually :D02:26
claygDHE: you could check it out with some experiments using swift-ring-builder and swift-get-nodes02:28
*** itlinux has quit IRC02:28
kota_DHE: i don't think it's ensured02:33
kota_that's what mattoliverau_ worked in those days, https://review.openstack.org/#/c/199863/02:34
patchbotpatch 199863 - swift - Add handoff region affinity support to replicators02:34
kota_i know it's too old, if you want to use, we should make it revive02:34
*** mattoliverau_ is now known as mattoliverau02:35

ashok_nHi07:34
*** tovin07_ has quit IRC07:34
ashok_nI was trying to use container sync feature of Swift07:35
*** tovin07_ has joined #openstack-swift07:35
*** tovin07__ has quit IRC07:38
ashok_nin the documentation auth v1 is used but I was using auth v3, when I tried to sync two containers by specifying --os-storage-url instead of -t in the swift post command. instead of syncing the objects there is one 0-byte object created in both containers. The object name is container name of other container.07:38
ashok_nPlease help07:38
ashok_nthe problem is I could not find any replacement for --sync-to when using --os-storage-url. The container name in the swift post command is treated as object name.07:40
ashok_ncommand I used :  swift --os-key XXXX post --os-storage-url http://XXXXXX:XXX/v1/AUTH_b4af92fljaods3a3b1af9a1146a1d68e/test-sync-b -k 'XXXXX' test-sync-a07:43

kota_ashok_n: please check your command https://docs.openstack.org/python-swiftclient/latest/cli/index.html#swift-post08:56
kota_ashok_n: it looks like missing -t which means sync-to08:56
kota_even i used v1 auth, `swift post container -t <realm> -k secret` worked as I expected08:57
kota_that's minimum configuration when using environment variable for auth.08:57
openstackgerritKota Tsuyuzaki proposed openstack/python-swiftclient master: Add missing <sync-to> value in command line docs  https://review.openstack.org/54732909:06
ashok_nkota_ : Thank you for your reply, I tried with the -t <realm> as well, containers are created in both clusters but objects are not synced. I could not find anything from /var/log/syslog09:06
ashok_nExcept this error: proxy-server: ERROR WSGI: code 400, message Bad request syntax ('\x16\x03\x01\x02\x00\x01\x00\x01\xfc\x03\x03\x04(R"8\x81\x7f')09:07
ashok_nis this related sync operation, I double checked all the configurations but no luck09:07
ashok_nrelated to*09:08
kota_ashok_n: i don't think it copies immediately. IIRC, that sets metadata to synchronize the objects with backend container-sync daemon.09:08
kota_ah, ok. the container was synced via container-sync daemon, true/09:09
*** rcernin has joined #openstack-swift09:09
kota_true?09:09
ashok_nyes09:10
kota_and then, you uploaded an object, sync via the daemon, then... the object in the container was being 0-bytes? that's weird09:12
kota_oh, no09:13
kota_the object with 0-bytes is the name of the source container.09:13
kota_interesting09:13
ashok_nyes thats correct the object with 0-bytes is the name of the source container.09:15
kota_sorry, no idea for now. but it sounds like configuration issue around realm...09:15
kota_my knowledge was around the generation that takes full url path in default. not sure on realm configuration.09:16
ashok_nI think thats because I missed -k <realm>, I thought --os-storage-url is enough09:16
kota_oic.09:17
ashok_nbut later I user -k <realm> instead of --os-storage-url09:17
kota_--os-storage-url is for the auth, not container-sync configuration.09:17
ashok_nYeah09:17
ashok_nLater the commands are successfully executed, new containers are created in each cluster09:18
ashok_nbut objects are not synced09:18
ashok_nMay be I will try Old way09:18
ashok_nusing allow_hosts option09:18
ashok_nThank you for your help :)09:19

mrjkMorning14:55
mrjknotmyname, timburke , about my S3 compatibility problem yesterday, I believe that was the auth protocol version issue, we had to stick to v214:56
mrjkI guess some newer version might be supported according some commits in swift3 master, but ... that's gonna be for another time :) Thank for your time14:58
