[Touch-packages] [Bug 1611945] Re: /dev/disk/by-path not properly populated for (e)SATA port multiplier disks

The related upstream issue references a PR that was merged upstream 3 years ago: https://github.com/systemd/systemd/issues/3943#issuecomment-625791141. Based on that, I am marking this Fix Released, but please re-open if this is observed on newer releases. ** Changed in: systemd (Ubuntu)

I saw the discussion in zfs-discuss and read a bit for fun. To answer some old questions from what i understood from linked resources: This bug/deficiency seem to make it impossible to see all drives behind a port multiplier when using links in /dev/disk/by-path/ but not other links, making the

Ladies and Gentlemen, The technical stuff is way over my head but I am getting the same syslog errors and the same inconsistent device paths on an HP Proliant ML110 G7 with Ubuntu 16.04.3 kernel 4.4.0-98-generic. It seems clear that no-one is taking ownership of this to fix it in an actual update

I've confirmed this behavior on the yakkety live build you linked to above, with systemd 231 according to its dpkg output. I gathered as much data about it as I could think of (and I can go back for more if necessary). Would you rather I pass the data to you here for you to file an upstream bug

[Touch-packages] [Bug 1611945] Re: /dev/disk/by-path not properly populated for (e)SATA port multiplier disks

In 16.04 (and I think everywhere), /sys is sysfs, so its contents are generated by the kernel, device drivers, and so on. Udev looks at sysfs in order to determine device information (eg ATA port number) that it uses to create everything else. How hardware is represented in sysfs can change over

I thought everything in /sys was built by udev rules? If so any path changes could be down to changes there rather than in the kernel. http://cdimage.ubuntu.com/daily-live/20160811/ is likely a new yaketty build but use at your own risk etc. -- You received this bug notification because you are

Here is the full 'udevadm test' output for two disks on the same port multiplier channel. I can do a disk on a different channel as well if you want. On 12.04, the sysfs path of the same disk slot is
