So the service is started too early as it seems. The crash brings me into serious trouble, as then instances with attached volumes don't get access to their volumes. Terminating instances then leads to zombie instances and attached volumes that can't be detached anymore. Sorting out things manually in the nova database enabled me to start all instances again and properly attach all volumes. But nothing i want to do on every reboot of that node. Any suggestions? With pohysically attached disks thinsg work fine of course. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1157599 Title: Using an iscsi device in the nova-volume VG lets nova-volume crash on system boot To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/1157599/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
