[lustre-discuss] Building lustre with zfs only

[Christopher J. Morrone]

Is your OS CentOS 6.7 then?  You _might_ be hitting bug LU-7534, but I'm 
not sure how DKMS behaved under CentOS 6.7.

Do the following directories exist on your system?

    /var/lib/dkms/spl/0.6.4.2/build
    /var/lib/dkms/zfs/0.6.4.2/build

If not, then you need my patch from LU-7534.
