[lustre-discuss] Lustre version 2.14 support for CentOS 7

[Nathaniel Clark]

If you've installed the zfs rpms:

zfs, kmod-zfs, kmod-zfs-devel, kmod-zfs-devel-$(uname -r), libnvpair3, 
libuutil3, libzfs4, libzfs4-devel, libzpool4

You should be able to configure lustre via:

sh autogen.sh

./configure --with-zfs

make rpms

The auto conf will pick up the current kernel and all the installed ZFS 
paths without having to specify them.

Sincerely,

Nathaniel Clark
