Hi Dan,

Pre-loading the erasure code plugins will reduce this race condition (i.e. the files will have to be modified between the start of the ceph-osd process and the bootstrap phase where it loads the plugins for it to happen) and it seems to be preferable to stopping the daemons. Thanks for giving an additional incentive to go in this direction !

Cheers
