[Bug 1830169] Re: lvm udev rule fails to call systemd-run

[Brian Murray]

Hello bugproxy, or anyone else affected,

Accepted lvm2 into cosmic-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/lvm2/2.02.176-4.1ubuntu3.18.10.1 in
a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-cosmic to verification-done-cosmic. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-cosmic. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Bug description:
  [Impact]
  Judging from the rule, this probably means that volumes do not disappear when the physical volume disappears.

  [Test case]
  Not available. But since it's just a path fix, it should not be a problem.

  [Regression potential]
  Removal might now actually work correctly, but it's not entirely clear how that could cause a regression.

  [Other info]
  In /lib/udev/rules.d/69-lvm-metad.rules file, it calls /bin/systemd-run command during removal -------
     ACTION!="remove", ENV{LVM_PV_GONE}=="1", RUN+="/bin/systemd-run /sbin/lvm pvscan --cache $major:$minor", GOTO="lvm_end"

  But /bin/systemd-run is not found,  in fact systemd-run is in /usr/bin
  /systemd-run.

  xxxxxxxxxx:~$ cat /etc/issue
  Ubuntu 18.04.2 LTS \n \l

  xxxxxxxxxx:~$ ls /bin/systemd-run
  ls: cannot access '/bin/systemd-run': No such file or directory

  xxxxxxxxxx:~$ ls /usr/bin/systemd-run
  /usr/bin/systemd-run
