Ceph

work in progress

• add ceph osd pool create [name] [key=value] where key and value are arbitrary strings.
  • Update ceph osd pool create around MonCommands.h
  • Add a map<string,string> erasure_code parameter list to pg_pool_t
• configuration example ( osd pool create keys interpreted by the plugin )
  • ceph osd pool create poolname erasure-code-dir=/var/lib/ceph/erasure-code-plugins (mandatory)
    erasure-code-plugin=jerasure (mandatory) erasure-code-m=10 (optional) erasure-code-k=3 (optional) erasure-code-algorithm=Reed-Solomon (optional)
  • ... there can be more, depending on the plugin / algorithm
  • we can probably generalize the mon command interface to have a key/value list type that will make this easy to plumb from the CLI (and trivial via ceph-rest-api).
