[Bug 2003530] Please test proposed package

[Steve Langasek]

Hello Peter, or anyone else affected,

Accepted ceph into kinetic-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/ceph/17.2.6-0ubuntu0.22.10.1 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, what testing has been
performed on the package and change the tag from verification-needed-
kinetic to verification-done-kinetic. If it does not fix the bug for
you, please add a comment stating that, and change the tag to
verification-failed-kinetic. 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.

Title:
  Rook mgr module crashes due to missing mgr.nfs

Status in ceph source package in Kinetic:
  Fix Committed
Status in ceph source package in Lunar:

Bug description:
  [Impact]

  The rook mgr service crashes on installing the ceph-mgr-rook package
  (see below traceback from /var/log/syslog). This is due to a missing
  ceph mgr package "nfs" which the rook mgr module depends upon.

  This makes the rook mgr module unusable which is required for
  integrating Ceph with the Rook storage orchestrator.

  The proposed patch fixes this by including the nfs mgr package into
  the ceph-mgr-modules-core .deb. This is similar as upstream packages
  nfs for the ceph mgr system.

  [Test plan]

  The test requires a Ceph cluster. SSH to a system with a running ceph-
  mon service.

  $ sudo ceph mgr module ls  # verify: no rook mgr module
  $ sudo apt-get -q install ceph-mgr-rook
  $ sudo ceph -s  # verify: no crashed modules
  $ sudo ceph mgr module ls  # verify: rook mgr module present and enabled

  
  [Where problems could occur]

  The proposed patch only includes an additional Python package, and
  regression potential should be low.

  Issues could occur due to packaging bugs, such as missing dependencies
  for the nfs mgr package. As the nfs package is currently missing,
  there should not be any additional impact due to this.
