[lustre-discuss] Trying to rebuild all Lustre rpms with zfs 0.6.4.2 -- and failing

[Bob Ball]

Hi,

I'm looking for someone who can give me advice on a problem I am having 
rebuilding the full set (server and client) of Lustre rpms, including 
zfs support on the server side.  The 2.7.0 rpms as distributed were 
built with zfs 0.6.3, and do not work with 0.6.4.

So, I follow the directions here, fetching the current git source which 
is something like 2.7.56:
https://wiki.hpdd.intel.com/pages/viewpage.action?pageId=8126821
I modified this as follows to include zfs:

cd /usr/src/spl-0.6.4.2/
./configure --with-config=kernel
make all
cd ../zfs-0.6.4.2/
./configure --with-config=kernel
make all

Then, when I reach the stage of building the Lustre rpms, I prepare by
./configure 
--with-linux=/home/build/kernel/rpmbuild/BUILD/kernel-2.6.32.504.16.2.el6_lustre/ 
--with-zfs=/usr/src/zfs-0.6.4.2 --with-spl=/usr/src/spl-0.6.4.2

I install the kernel rpm, create the initramfs, and reboot.

This is where it all goes horribly wrong.  Our systems are built with 
LVM partitions, with the exception of the /boot partition on /dev/sda1.  
grub.conf is seen there in sda1, the kernel choice is made, it starts 
going.  Then nothing.  The console goes silent.  It appears that the 
kernel cannot access the LVM partitions.  From everything I can see, 
dracut knows about them, but I am at a loss on how to proceed.

/sbin/new-kernel-pkg --package kernel --mkinitrd --dracut --depmod 
--install 2.6.32.504.16.2.el6_lustre

title Scientific Linux (2.6.32.504.16.2.el6_lustre)
         root (hd0,0)
         kernel /vmlinuz-2.6.32.504.16.2.el6_lustre ro 
root=/dev/mapper/vg0-lv_root rd_NO_LUKS rd_LVM_LV=vg0/lv_root

         initrd /initramfs-2.6.32.504.16.2.el6_lustre.img

Can anyone advise me on how to proceed with this?  I'd really like to 
get the upgraded zfs in use over the 0.6.3 that is running now.

Thanks,
bob
