Yes, multipath is the problem here. When multipath is enabled we have a different sysfs structure. I'll have to work up a fix. Can you move ahead with the code as it is, and then we can provide a bug fix patch when ready? This chreipl bug should not impede NVMe installation or a normal boot process. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1902179 Title: [20.04 FEAT] Support/enhancement of NVMe IPL To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1902179/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
