The challenge here is that libzfs is currently a build time dependency, which means it needs to be included in the target distro already, or we need to bundle it in the Ceph.com repos.
I am currently looking at the possibility of making the OSD back end dynamically linked at runtime, which would allow a separately packaged zfs back end; that may (or may not!) help. sage Dinu Vlad <dinuvla...@gmail.com> wrote: >Any chance this option will be included for future emperor binaries?
