** Description changed: + [Impact] + + * Fallback device detection for multipath connections is currently + broken. + + [Test Case] + + * Enable cinder/nova multipath but do not make multiple paths available + (such that are no /dev/disk/path/by-id/dm* devices) + + * Create a cinder volume and attach to Nova instance + + * Check that volume was attached successfully and that /var/log/nova + /nova-compute.log does not display the error mentioned below. + + [Regression Potential] + + * None + + SUMMARY: Wrong path used when detecting multipath id ANALYSE: when multipath device path was not found via LUN wwn, os-brick would use device path like below: /dev/disk/by-path/ip-192.168.3.52:3260-iscsi- iqn.1992-04.com.emc:cx.apm00153906536.b5-lun-155 to detect multipath id via 'multipath -l <device path>' but this cause error: : can't get udev device actually, we should use its real path like /dev/sdb, dev/sda to detect the multipath id. ** Tags removed: verification-needed ** Tags added: verification-done -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1585940 Title: [SRU] ERROR "can't get udev device" when iscsi multipath enabled To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-archive/+bug/1585940/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
