            One patch was missed due to GSS not being tested. It is at http://review.whamcloud.com/#/c/8396. Please inspect.

            All that is left is some NFS patches but this is a general 3.X problem.I guess we can migrate all further information to LU-3079. Peter can you close this ticket.

            Thanks Cory. For 3.8 to work properly you need the following patches:

            http://review.whamcloud.com/#/c/5974 - LU-2686
            http://review.whamcloud.com/#/c/5763 - LU-2987

            http://review.whamcloud.com/#/c/6715 - LU-3483
            http://review.whamcloud.com/#/c/6726 - LU-3484

            Optional cleanup patch

            http://review.whamcloud.com/#/c/5505 - LU-2800

            FYI, LU-3484 and LU-3486 are needed for 3.8 kernels (for NFS export).

            The only thing is I have modify http://review.whamcloud.com/#change,5655 due to conflicts with the patch from LU-2059 and LU-2800 autoconf patch. Needs updating as well. At this point it is hard to say which will land first.

            Yep. I run it on small production cluster with lustre/zfs 2.4rc2
            servers are 3.8.6 clients are both 3.8.6 and 3.9.4

            With the above listed patches and patches from LU-3079 I get this.

            LNet: HW CPU cores: 8, npartitions: 2
            alg: No test for crc32 (crc32-table)
            alg: No test for adler32 (adler32-zlib)
            LNet: Added LNI 10.37.248.7@o2ib1 [8/2560/0/180]
            Lustre: Lustre: Build Version: 2.4.50-g2f41b68-CHANGED-3.9.4
            Lustre: Layout lock feature supported.
            Lustre: Mounted lustre-client

            It appears to work. We have Lustre 3.9.4 clients. With this I can start my work on ldiskfs for 3.9.4.
