You have been subscribed to a public bug: The udev-generated /dev/disk/by-path names for virtio disks are broken on z Systems as they have the format virtio-pci-h.h.hhhh[-partn], where h.h.hhhh is the CCW devno of the virtio device representing the whole disk. Historically, the standard CCW naming was applied, which was ccw-h.h.hhhh[-partn] ---uname output--- Linux ubuntu 4.4.0-36-generic #55-Ubuntu SMP Thu Aug 11 18:05:09 UTC 2016 s390x s390x s390x GNU/Linux Machine Type = 2964-703 running KVM for IBM z Systems ---Debugger--- A debugger is not configured ---Steps to Reproduce--- 1. Install Ubuntu LTS 16.04.1 on KVM for IBM z Systems 1.1.1 2. Issue ls -l /dev/disk/by-path Userspace tool common name: udev The userspace tool has the following bit modes: 64-bit
Userspace rpm: udev Userspace tool obtained from project website: na There are basically two problems with this: 1. The naming is technically incorrect, since the virtio devices on z are no PCI devices but CCW devices 2. Then naming based on virtio- is backwards incompatible. This may seem not to be an issue for Xenial but customers may be confused if they have been running Linux on KVM for IBM z before. ** Affects: ubuntu-z-systems Importance: Medium Assignee: Dimitri John Ledkov (xnox) Status: New ** Affects: systemd (Ubuntu) Importance: Undecided Assignee: Skipper Bug Screeners (skipper-screen-team) Status: Invalid ** Tags: architecture-s39064 targetmilestone-inin16041 -- udev-generated /dev/disk/by-path names broken for virtio disks https://bugs.launchpad.net/bugs/1623003 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to systemd in Ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
