Bug 374913 – After booting into an encrypted system, /dev/mapper/root is missing

• Status: RESOLVED NEEDINFO
• Product: Gentoo Linux

[Description Sebastian Heyn 2011-07-12 07:50:44 UTC]

As mentioned above /dev/mapper/root is missing. 
This bug has been reported before, but seems to reappear on my system
I rate this as major, because rootfs is not checked at boot time which i find critical for system stability.



Reproducible: Always

Steps to Reproduce:
1. Encrypt the system
2. Boot

Actual Results:  
fsck doesnt find /dev/mapper/root

Expected Results:  
fsck should find /dev/mapper/root

server ~ # mount
rootfs on / type rootfs (rw)
/dev/mapper/root on / type ext2 (rw,noatime,errors=continue)


server ~ # ls /dev/mapper/
control  datadrv


server ~ # emerge udev genkernel gentoo-sources -vp

These are the packages that would be merged, in order:

Device mapper is installed into the kernel, not as module.
The initial ramdisk is created with
--no-ramdisk-modules --luks --disklabel
