[openstack-dev] [cinder] Fixing stuck volumes - part II

At the cinder mid-cycle it was decided that the best way to fix volumes stuck in 'attaching' or 'detaching' was NOT to fix the broken reset-state command. The doc string and help message for reset-state have been modified to warn the user that the tool only affects Cinder DB and can cause

Re: [openstack-dev] [Cinder]Behavior when one cinder-volume service is down

I’m just not sure that you can evacuate with the c-vol service for those volume down. Not without the un-safe HA active-active hacks. In our public cloud, if the c-vol service for a backend/volumes is down, we get woken up in the middle of the night and stay at it until we get c-vol back up.

Eduard, Gorka has done a great job of explaining some of the issues with Active-Active Cinder-volume services in his blog: http://gorka.eguileor.com/ TL;DR: The hacks to use the same hostname or use Pacemaker + VIP are dangerous because of races, and are not recommended for Enterprise

Re: [openstack-dev] [oslo][all] The lock files saga (and where we can go from here)

Could the work for the tooz variant be leveraged to add a truly distributed solution (with the proper tooz distributed backend)? IF so, then +1 to this idea. Cinder will be implementing a version of tooz based distribute locks, so having it in Olso someday is a goal I'd think.

Re: [openstack-dev] [nova][cinder] volumes stuck detaching attaching and force detach

Matt, changing Nova to store the connector info at volume attach time does help. Where the gap will remain is after Nova evacuation or live migration, when that info will need to be updated in Cinder. We need to change the Cinder API to have some mechanism to allow this. We'd also like Cinder
