Question Dracut: Fails to unlock/mount LUKS after update


Hello,

First, I apologize in advance if this is the wrong forum, first time posting on this board.

Distro: Hardened Gentoo

I have recently upgraded my bootloader from GRUB Legacy (0.97-r12) to GRUB2 (2.00_p5107-r2), my kernel from 3.9.9-hardened to 3.11.7-hardened-r1, and Dracut from 031-r1 to 036-r4. After this, I used dracut to create an initramfs for 3.11.7-hardened-r1. It now fails to mount my encrypted swap and home LVs. I have been troubleshooting this for about a day now and have hit a roadblock. No matter what I do I can't get them to mount. I still have my 3.9.9 kernel and initramfs in GRUB2, and those mount/unlock my home and swap without issue.

Examining the logs shows the difference but I can't seem to locate what settings might have changed.

New kernel & dracut log:

cat /boot/grub/grub.cfg: http://bpaste.net/show/193682/
cat /etc/dracut.conf: http://bpaste.net/show/193684/

I don't understand why it unlocks and mounts the root LV but not the swap or /home :/

Any help would be great!

Update:

Narrowed the problem down to dracut failing to run lvchange on non-root LVs. Suggestions to rectify this appreciated... or if this should be a bug report, let me know so I can file it.

In the meantime, my current workaround is to add lvchange -aly vg/home && lvchange -aly vg/swap && swapon && mount /home to my /etc/kde/startup/agent-startup.sh and umount /home to /etc/kde/shutdown/agent-shudown.sh.

Solution found:

Problem was config option hostonly="yes" in /etc/dracut.conf. After commenting out, dracut-generated initramfs works as expected using both versions 0.34-r4 and 0.36-r4. See http://forums.gentoo.org/viewtopic-p-7523742.html for more info.

Marking thread solved.
