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 LANG=en_US.UTF-8 rd_NO_MD rhgb quiet selinux=0 rd_LVM_LV=vg0/lv_swap SYSFONT=latarcyrheb-sun16 crashkernel=auto KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM rhgb quiet printk.time=1 console=tty0 console=ttyS1,57600n8 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
