I can confirm that the daily 17.10 build does not exhibit the problem. Interestingly, the first time we tried we forgot to stop running IO to our iSCSI volumes and it _looked_ like we reproduced the problem, then the IOs timed out and our application stopped and we were able to complete the reboot.
The next time we retried and correctly stopped our application before shutting down and had no issue. Whatever it is, is fixed in 17.10. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1569925 Title: Shutdown hang on 16.04 with iscsi targets To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1569925/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
