to my knowledge, the only distribution with support for Lustre on Ubuntu
is Qlustar (qlustar.com). Qlustar 9 due out next week will come with
Lustre 2.6 support out of the box. Note however, that we dropped ldiskfs
support in Qlustar 9 and are only offering ZFS as the storage back-end.
If you need more information about Qlustar let me know.
