Re: [Openstack] [Swift] : Ring Algorithm

2017-02-09 Thread Mark Kirkwood
Hi Sameer, A good question - the docs do mention a 'far apart as possible' distribution algorithm. If you study the code (in swift/common/ring*.py) there is a discussion of tiers (zone and region) which relate to this concept. Now I've not studied this in enough detail myself (yet) to give yo

Sam, I see a VolumeNotFound in your pasted log. What does “openstack volume list” return (when using admin credentials)? Is the volume present and created? Are there any firewalls blocking iscsi ports on Nova or Cinder (usually port 3260)? You can reset the Cinder volume state for testing with

Hi guys, I meet this issue when deploying Mitaka. When I attach LVM volume to VM, it keeps state "Attaching". I am also unable to boot VM from volume. This is /var/log/nova/nova-compute.log in Compute node when I attach volume. http://paste.openstack.org/show/598282/ Mitaka version: http://prnts

2017-02-09 Thread Tomáš Vondra
Hi Jim! I think that the plan is good. I think Cinder should not delete anything unless told to do so. You have to create the CPG space manually before Cinder can start using it, so it does no initialization. Do you have opportunity to test it, on some other CPG perhaps? We have the same setup
