[Kernel-packages] [Bug 1728739] Re: Attempt to map rbd image from ceph jewel/luminous hangs

2018-01-28 Thread Aaron
Actually, upgrading my kernel to 4.13 fixed the issue for me.

root@myserver:~$ uname -r
4.13.0-32-generic
root@myserver:~$ rbd ls
testimage
root@myserver:~$ rbd map testimage

  Attempt to map rbd image from ceph jewel/luminous hangs

Status in linux package in Ubuntu:

Status in linux source package in Xenial:

Bug description:
  [Impact]

  Attempting to map an rbd image using the 4.4 LTS (Xenial) kernel
  client from a Jewel or Luminous Ceph cluster with optimal tunables
  fails due to feature set mismatch.

  The Jewel release of Ceph introduced a new set of CRUSH tunables.
  These tunables were first introduced in the 4.5 Linux kernel and are
  thus not available in the 16.04 LTS 4.4 Linux Kernel. Attempting to
  map RBD images as block devices will fail due to not being able to
  understand these new tunables:

  (from kern.log)

  Oct 30 21:19:05 ceph-7 kernel: [  815.692897] libceph: mon0 10.5.0.19:6789 
missing required protocol features

  Support for the new CRUSH tunables were added in upstream kernel 4.5
  in http://www.spinics.net/lists/ceph-devel/msg28421.html.

  [Test Case]

  1. Deploy a Jewel or Luminous Ceph cluster.
  2. Create rbd image suitable for the kernel client:
$ rbd create --pool rbd --image-feature layering --size 1G test
  3. Map the rbd image to the local server:
$ rbd map --pool rbd test

  [Regression Potential]

  Minimal. Code is limited to kernel rbd driver and new code should
  primarily affect clients connecting to clusters with the new tunables
  options.

  [Additional Info]

  A workaround is to change the crush tunables configured for the Ceph
  cluster to a legacy version (hammer or lower) via:

  $ ceph osd crush tunables hammer

  However, changing the tunables to hammer fails to allow the cluster to take 
advantage of newer placement strategies which reduces the amount of data 
movement throughout the cluster.

2017-11-29 Thread Billy Olsen
Successfully verified this with kernel 4.4.0-102-generic in the xenial-
proposed repository.

I verified mapping rbd devices against Ceph versions:

0.94.10 Hammer release (from trusty-kilo cloud-archive)
10.2.7  Jewel release (from xenial-updates)
12.2.0  Luminous release (from xenial-pike cloud-archive)

All versions had optimal tunables set, which previously prevented rbd
mapping from completing for Jewel and Luminous releases due to missing
TUNABLES5 support. All tests successfully mapped, formatted, and
mounted.

  Attempting to map an rbd image using the 4.4 LTS (Xenial) kernel
  client from a Jewel or Luminous Ceph cluster with optimal tunables
  fails due to feature set mismatch.

  The Jewel release of Ceph introduced a new set of CRUSH tunables.
  These tunables were first introduced in the 4.5 Linux kernel and are
  thus not available in the 16.04 LTS 4.4 Linux Kernel. Attempting to
  map RBD images as block devices will fail due to not being able to

2017-11-28 Thread Khaled El Mously
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
xenial' to 'verification-done-xenial'. If the problem still exists,
change the tag 'verification-needed-xenial' to 'verification-failed-
xenial'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

  Attempting to map an rbd image using the 4.4 LTS (Xenial) kernel
  client from a Jewel or Luminous Ceph cluster with optimal tunables
  fails due to feature set mismatch.

  The Jewel release of Ceph introduced a new set of CRUSH tunables.
  These tunables were first introduced in the 4.5 Linux kernel and are
  thus not available in the 16.04 LTS 4.4 Linux Kernel. Attempting to
  map RBD images as block devices will fail due to not being able to
  understand these new tunables:

missing required protocol features

  Support for the new CRUSH tunables were added in upstream kernel 4.5
  in http://www.spinics.net/lists/ceph-devel/msg28421.html.

  [Test Case]

  1. Deploy a Jewel or Luminous Ceph cluster.
  2. Create rbd image suitable for the kernel client:
$ rbd create --pool rbd --image-feature layering --size 1G test
  3. Map the rbd image to the local server:
$ rbd map --pool rbd test

  [Regression Potential]

  Minimal. Code is limited to kernel rbd driver and new code should
  primarily affect clients connecting to clusters with the new tunables
  options.

  [Additional Info]

  A workaround is to change the crush tunables configured for the Ceph
  cluster to a legacy version (hammer or lower) via:

  $ ceph osd crush tunables hammer

  However, changing the tunables to hammer fails to allow the cluster to take 
advantage of newer placement strategies which reduces the amount of data 
movement throughout the cluster.
