Description Erik Logtenberg 2014-06-15 19:13:20 UTC 
Description of problem:

The ceph package is missing some of the erasure code libraries. In the Fedora package, these files are included in the /usr/lib64/ceph/erasure-code directory:

libec_example.so -> libec_example.so.0.0.0
libec_example.so.0 -> libec_example.so.0.0.0
libec_example.so.0.0.0
libec_fail_to_initialize.so -> libec_fail_to_initialize.so.0.0.0
libec_fail_to_initialize.so.0 -> libec_fail_to_initialize.so.0.0.0
libec_fail_to_initialize.so.0.0.0
libec_fail_to_register.so -> libec_fail_to_register.so.0.0.0
libec_fail_to_register.so.0 -> libec_fail_to_register.so.0.0.0
libec_fail_to_register.so.0.0.0
libec_hangs.so -> libec_hangs.so.0.0.0
libec_hangs.so.0 -> libec_hangs.so.0.0.0
libec_hangs.so.0.0.0
libec_jerasure.so -> libec_jerasure.so.2.0.0
libec_jerasure.so.2 -> libec_jerasure.so.2.0.0
libec_jerasure.so.2.0.0
libec_missing_entry_point.so -> libec_missing_entry_point.so.0.0.0
libec_missing_entry_point.so.0 -> libec_missing_entry_point.so.0.0.0
libec_missing_entry_point.so.0.0.0

However these libraries (that are included in the official ceph package, located here: http://ceph.com/rpm/fc19), are missing:

libec_jerasure_generic.so -> libec_jerasure_generic.so.2.0.0
libec_jerasure_generic.so.2 -> libec_jerasure_generic.so.2.0.0
libec_jerasure_generic.so.2.0.0
libec_jerasure_sse3.so -> libec_jerasure_sse3.so.2.0.0
libec_jerasure_sse3.so.2 -> libec_jerasure_sse3.so.2.0.0
libec_jerasure_sse3.so.2.0.0
libec_jerasure_sse4.so -> libec_jerasure_sse4.so.2.0.0
libec_jerasure_sse4.so.2 -> libec_jerasure_sse4.so.2.0.0
libec_jerasure_sse4.so.2.0.0
libec_test_jerasure_generic.so -> libec_test_jerasure_generic.so.0.0.0
libec_test_jerasure_generic.so.0 -> libec_test_jerasure_generic.so.0.0.0
libec_test_jerasure_generic.so.0.0.0
libec_test_jerasure_sse3.so -> libec_test_jerasure_sse3.so.0.0.0
libec_test_jerasure_sse3.so.0 -> libec_test_jerasure_sse3.so.0.0.0
libec_test_jerasure_sse3.so.0.0.0
libec_test_jerasure_sse4.so -> libec_test_jerasure_sse4.so.0.0.0
libec_test_jerasure_sse4.so.0 -> libec_test_jerasure_sse4.so.0.0.0
libec_test_jerasure_sse4.so.0.0.0

Ceph uses libec_jerasure_sse3.so if you create an erasure coded pool on a machine that supports sse3, and if that library is missing, you cannot create or run such a pool at all.

Version-Release number of selected component (if applicable):

ceph-0.80.1-2.fc19

How reproducible:

100%

Steps to Reproduce:
1. Install ceph packages
2. Observe missing libraries in /usr/lib64/ceph/erasure-code
3. Try to create erasure coded pool on SSE3-enabled machine

Actual results:

# ceph osd pool create test123 100 100 erasure default
Error EIO: failed to load plugin using profile default

Expected results:

# ceph osd pool create test123 100 100 erasure default
pool 'test123' created

Need more info? Would it help if I submit a patch?
Comment 2 Dan Mick 2014-06-30 18:27:03 UTC 
The Fedora spec file needs lots of love (needs to basically be refreshed, perhaps even sourced, perhaps with automated edits) from the spec file contained in the Ceph repo.  I am completely new to Fedora packaging and have been occupied with a release cycle; Kaleb shifted this bug to me in hopes that I'd have some time, which I haven't yet.

If you want to start by trying to use or slightly adapt the spec file contained in the Ceph sources, that would be a great help for the technical side of this, and then I can both review and focus on the process side.

Thanks for the offer.
Comment 3 Boris Ranto 2014-08-17 16:06:11 UTC 
I've synced up the spec files and these files should no longer be missing in the latest build (I'll attempt to get the build to the updates-testing repo asap).
