Sorry for the long delay. This is fixed in oslo.vmware 0.9.0. https://github.com/openstack/oslo.vmware/commit/a229faf8ba59724a4fda3f37d5a7473376f93d9c From: hao wang [mailto:sxmatch1986 at gmail.com] Sent: Saturday, May 30, 2015 12:40 PM To: openstack-dev at lists.openstack.org Subject: [openstack-dev] [openstack][cinder]VMware: concurrent create two volumes, one is failed when vcenter session is timout The default timeout about vCenter server(5.5 used) is 30 minutes, so when session is timeout and then concurrent create two volumes through cinder API. There will be one of volumes creation failed. The error log is here: http://paste.openstack.org/show/246678/ Looks like if there is concurrent requests, the vmware driver will re-create the session both at same time. I'm not sure whether it is the issue point. Need some help from VMware engineer, thanks. -- Best Wishes For You! -------------- next part -------------- An HTML attachment was scrubbed...
