  1. <tbarron> rraja: so are they running separate share services on different physical nodes pointing at the same cluster with the idea that either service can stand in for the other at any time?
  2. <rraja> tbarron: I think so.
  3. <tbarron> rraja: if they want an active-active share service then that is not currently supported in manila, it's not a backend-specific issue.
  4. * absubram (~absubram@173.38.117.88) has joined
  5. <tbarron> rraja: this is parallel to the state of cinder today
  6. <tbarron> rraja: you can run share service active/passive with a solution like pacemaker though
  7. <rraja> tbarron: hmmm. interesting. he said that he uses a similar configuration in Cinder. that's why I wanted to double check with you
  8. <openstackgerrit> Merged openstack/puppet-manila: Enable release notes translation https://review.openstack.org/383344
  9. <tbarron> rraja: but I don't think that poses a problem for the assumption that only one manila service governs (does eviction, etc.) at any given time.
  10. <rraja> tbarron: http://pastebin.com/tTHPrxvu
  11. <tbarron> rraja: there *are* deployments out there that run cinder active-active, at their own risk, but upstream (and downstream at a place you and I know) it is not considered safe
  12. <tbarron> rraja: looks like they play tricks in cinder to have multiple cinder volume servers answer on the message queue as the same "host"
  13. <tbarron> rraja: there is ongoing work to make that kind of active-active cinder volume service safe but it has not yet landed
