scottdathingee: maybe not. I wasn't sure if there were other issues.15:54
scottdaaround endpoints.15:54
thingeein the past the issue was because of ha proxy cases and ssl termination15:54
DuncanTI don't think we need a summit session; the issue is well understood (other than the fact it needs to be configurable and default to off, for security reasons) and the code is in several otehr projects15:54
thingeewe eliminated this problem in Kilo i think with a config option15:54
thingeehowever, expecting deployments to be using kilo was not ideal15:55

sjacksonHello all. I have Juno using ceph as a cinder backend. The ceph cluster has some issues and I need to rebuild it. My first thought is to add secondary cinder storage (another ceph cluster or normal cinder) and migrate the data. Was wondering if anyone knew if it was possible to add a 2nd cinder/ceph cluster, and if os, it it possible to migrate 100% of my data off the old cluster?17:21
DuncanTsjackson: I don't know the status of volume migration in Juno, but it is certainly possible in Kilo onwards. I think it is ok - should be easy enough to spin up a ceph based devstack and test it17:24

jgriffithscottda: thanks for hosting22:10
jgriffithhemna: I look forward to seeing a WIP with the implementation you're proposing22:10
jgriffithhemna: if you're doing anything more than taking my patch and moving the create-attachment entry to reserve volume I'd be interested in hearing more.22:12
*** dflorea has quit IRC22:12
hemnareally, the only difference is 1) returning attachment_id in os-reserve and 2) passing in attachment_id into initialize_connection.22:13
jgriffithhemna: in other words there is no difference?22:13
hemnawell, it's important22:13
jgriffithhemna: how come?22:13
hemnabecause initialize_connection can't find the correct attachment w/o it.22:14
jgriffithhemna: wait22:14
jgriffithfirst22:14
jgriffithanswer that question... is there any difference then in the impl?22:14
hemnaas I mentioned in the meeting, line 920 doesn't get you the correct attachment, you get a random attachment entry.22:14
jgriffithhemna: why can't initialize_connection not find something?  And what is the "correct attachment" ?22:14
jgriffithhemna: umm... that's a stub because multi-attach is broken22:15
jgriffithbut I can fix that22:15
jgriffithhemna: what I'm asking is how are you proposing to fix that?22:15
hemnaand the attachment entry doesn't exist yet then.22:15
jgriffithhemna: sure it does... line 90722:15
jgriffithbut regardless.. how are you fixing it?22:16
jgriffithhemna: don't get me wrong, you may have the perfect solution22:16
jgriffithhemna: I want to understand22:16

hemnathe volume_attachment row22:17
hemnathere is no entry in the volume_attachment table yet until later.22:17
jgriffithhemna: sure22:17
jgriffithhemna: that just means there's no existing attachment22:18
jgriffithso who cares?22:18
hemnaso you aren't going to be working on the right attachment row in the db.22:18
jgriffithhemna: if there isn't an entry in the db it means nothings been attached so there is no such thing as a correct row22:18
hemnahttps://github.com/openstack/cinder/blob/master/cinder/volume/manager.py#L98622:19
hemnathat's where the row is created22:19
jgriffithhemna:  I don't understand your point at all22:19
jgriffithhemna: and clearly we already know that the code in master as it is doesn't work22:19
hemnaline 947 in your code won'd do anything22:19
hemnait won't be updating the record in the DB, because it doesn't exist yet.22:19

jgriffithhemna: that creates the entry22:20
*** raunak_ has quit IRC22:20
jgriffithhemna: alright22:20

hemnayah22:23
jgriffithhemna: I don't think we need to waste your time22:24
hemnathe db record in volume_attachment doesn't get created until os-attach22:24
