simondodsleyIf I am using Cinder as the Glance store, but Glance is configured for 3 node HA, two questions: 1) Is Glance in HA A/A/A or A/P/P, and 2) Does Glance require a separate Cinder volume for each HA instance, or can it use Cinder multi-attach?15:02
dansmithsimondodsley: you probably want whoami-rajat__ or rosmaita 15:07
whoami-rajat__simondodsley, hey, which openstack release are you using?15:13
*** whoami-rajat__ is now known as whoami-rajat15:13
simondodsleywhoami-rajat__: Victoria15:13
whoami-rajatsimondodsley, ok and are you using single store setup or multistore ?15:15
simondodsleysingle store15:15
whoami-rajatsimondodsley, ok, I'm not sure about 1) but for 2) all glance nodes should point to the same c-vol backend/service15:18
whoami-rajatwe implemented multiple stores for cinder in victoria where you can configure multiple cinder stores and point each store to a specific c-vol backend with the help of volume types15:18
whoami-rajatand use of multiattach is implemented in Xena release but it might be for a different purpose than you might be asking for15:18
simondodsleywhoami-rajat i get the single backend/service, but when the images are stored they will be n a cinder volume, but the question is if there needs to be a seperate volume for each glance instance, or can the multiple instances use a single cinder volume leveraging multi-attach15:19
whoami-rajatsimondodsley, ok, so for each glance image, there will be a cinder volume created (storing that image), we can't store multiple glance images in a single cinder volume15:41
simondodsleywhoami-rajat, understood. similar question in a Glance HA config does each Glance instance need its own copy of the same image, so there would be multiple cinder volumes for each image?15:49
jokke_simondodsley: whoami-rajat: All Glance nodes are active but there is only single volume per image. I think there was some issues with accessing that image through multiple g-apis which was very recently fixed with some of the multi-attach work Rajat has been doing. 15:49
simondodsleyjokke_, that's the info I needed. Thank you.15:49
jokke_IIRC the main issue was that if there is multiple g-api nodes trying to attach to the volume at very same time, they failed as there was no retry mechanism15:50
jokke_and cinder locks the volume while the attach happens15:51
simondodsleyso it is Xena where this is resolved?15:51
jokke_simondodsley: yeah I'm pretty sure this is the patch ecda7f640fe4e807ba07981abfc1a637ddb496cd in Xena release that solved the issue and allows Glance to do multiattach properly now15:53
simondodsleythanks15:53
jokke_simondodsley: The Cinder driver was for long time on a state "Yeah it kind of works but don't even think of doing anything weird with it" whoami-rajat has done lots of work to plug all those corner cases we've came across even me going on every second of them like "Should we really do this in the driver, seriously?" ;D15:58
jokke_so almost anything that actually works smooth with that driver is his fault :P15:59
simondodsleygood to know - I'll keep that in mind when my customer breaks it with their weird edge case :)16:00
