Hi Ceph,
Yesterday I implemented a simple erasure code plugin that can sustain the loss of a single chunk.
https://github.com/dachary/ceph/blob/wip-5878/src/osd/ErasureCodeExample.h
and it works as shown in the unit test
https://github.com/dachary/ceph/blob/wip-5878/src/test/osd/TestErasureCodeExample.cc
It would be of limited use in a production environment because it only saves 25% space ( M=2 K=1 ) over a 2 replica pool, but it would work.
I would very much appreciate a review of the erasure code plugin system and the associated example plugin :
https://github.com/ceph/ceph/pull/515
When it's good enough, creating a jerasure plugin will be next :-)
Cheers
