[Bug 1507244] Re: Missing erasure coding plugins for jerasure/neon and shec

[Brian Murray]

Hello Steve, or anyone else affected,

Accepted ceph into vivid-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/ceph/0.94.5-0ubuntu0.15.04.1 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 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 to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

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

  Missing erasure coding plugins for jerasure/neon and shec

Status in ceph source package in Vivid:
  Fix Committed
Status in ceph source package in Wily:
  Fix Committed
Status in ceph source package in Xenial:
  Fix Released

Bug description:
  [Impact]
  Neon optimized jerasure plugin is built but not included in packages; this results in use of the un-optimized jerasure plugin in this use case.

  Likewise the SHEC based plugin is built, but not shipped.

  A number of dangling symlinks are also installed in the ceph package.

  [Test Case]
  sudo apt-get install ceph
  ls -l /usr/lib/*/ceph/erasure-code
     <missing libec_jerasure_neon.so>
     <missing libec_shec.so>
     dangling symlinks.

  [Regression Potential]
  Minimal; The proposed fix just ensures that the missing plugins are built with a unversioned .so extension, and drops the dangling symlinks from the install.
