There were no answers to this, from anyone, so it appears this is not
solved?
So, I proceeded to follow the directions here
https://wiki.hpdd.intel.com/pages/viewpage.action?pageId=8126821
using the stock redhat 2.6.32-504.16.2 kernel and what appears to be
Lustre 2.7.52 sources. Some mods to this were needed, but I built the
kernel, and then successfully built Lustre rpms including the zfs and
spl modules for version 0.6.4.
BUT, when I boot the kernel following the directions to create the
initramfs, problems. The /boot/grub/grub.conf is clearly read, I can
choose between the stock kernel and the lustre kernel, but when it
leaves the grub prompts.... nothing. The console just sits without
echoing any of the bootup sequence, with only an underscore occasionally
flashing. I am left with no choice but to reboot back to the stock kernel.
The volumes with the exception of /boot are all lvm, and the
/var/log/dracut.log indicates that lvm is included in the initramfs
image, but the lvm volumes just don't seem to be accessed, just /boot
that is ext4. I am at a loss about what to do next, and would really
appreciate some advice from someone about what to do here.
Many thanks,
bob

OK, so, I am seeing EXACTLY the issue reported at the end of LU-6452 8

There is no response. Is there a solution?
This is Lustre 2.7.0 with (now) zfs 0.6.4.1-1, which was current when
the server was built. I see a number of recent Emails about updates
to Lustre sources against this zfs version, but is there a solution
for the standard set of 2.7.0 Lustre rpms? Or any solution that will
get me un-stuck?
[root@umdist01 ~]# cat /etc/redhat-release
Scientific Linux release 6.6 (Carbon)
[root@umdist01 ~]# uname -r
2.6.32-504.8.1.el6_lustre.x86_64
I note that my first OSS server, initially built in March against zfs
0.6.3-1, seems to be happy and definitely does not exhibit this
issue. That server has now also updated to 0.6.4.1, and I am loathe
to reboot it now (up for 40 days) for fear of losing access to all of
its stored files. Perhaps I should downgrade to the earlier zfs and
cut off automatic zfs updates from that repo?
Thanks,
bob
