I have a layered setup, with root being an lvm logical volume (/dev/mapper/data-root) that is on luks encrypted partition (/dev/md/irrational:3) that's on mdadm raid 1 (mirroring). (ext4->lvm->luks->mdadm). I have this configuration working well for the past few years on genkernel (currently using sys-kernel/genkernel-3.3.48). Here's the kernel command line: # cat /proc/cmdline BOOT_IMAGE=/kernel-genkernel-x86_64-3.13.0-gentoo-r1 root=/dev/mapper/data-root ro crypt_root=/dev/md/irrational:3 lvmraid=/dev/md126,/dev/md/irrational:3 real_root=/dev/mapper/data-root domdadm dolvm splash=silent,theme:default quiet CONSOLE=/dev/tty1 i915.semaphores=1 zswap.enabled=1 zcache If I switch to genkernel-next, the system won't boot, with this error message: --- Booting the kernel. mdadm: /dev/md/irrational:3 has been started with 2 drives. mdadm: /dev/md/126_0 has been started with 2 drives. 2 volume groups found. Device /dev/md/irrational:3 doesn't exist or access denied. /dev/md/irrational:3 does not contain a LUKS header. Please file a bug report with this message --- Note that it never asked me for the luks password. This is very weird, as the output up to the "doesn't exist" line is the same as genkernel, which works fine. It seems to find the luks partition in mdadm. Under both genkernel and genkernel-next, I use the same command to build the kernel and initrd: CLEAR_CACHE_DIR="yes" genkernel --mdadm --lvm --luks --kernel-cc=/usr/lib/ccache/bin/gcc --splash=default --menuconfig --install all with the /etc/genkernel.conf file in it's unmodified state as distributed by genkernel or genkernel-next. Here's some additional info, taken from the running system (booted using genkernel): # cat /proc/mdstat Personalities : [raid1] [raid6] [raid5] [raid4] md126 : active raid1 sda2[0] sdb2[1] 104320 blocks [2/2] [UU] md127 : active raid1 sda4[3] sdb4[2] 975686520 blocks super 1.2 [2/2] [UU] unused devices: <none> # ls -la /dev/md* -R brw-rw---- 1 root disk 9, 126 Mar 9 19:20 /dev/md126 brw-rw---- 1 root disk 9, 127 Mar 9 19:20 /dev/md127 -rw-r--r-- 1 root root 4 Mar 9 19:20 /dev/mdev.seq /dev/md: total 0 drwx------ 2 root root 80 Mar 9 19:20 . drwxr-xr-x 19 root root 7320 Mar 9 19:21 .. lrwxrwxrwx 1 root root 8 Mar 9 19:20 126_0 -> ../md126 lrwxrwxrwx 1 root root 8 Mar 9 19:20 irrational:3 -> ../md127 So, /dev/md/irrational:3 == /dev/md127. /dev/md126 is not used for booting; it's just another mdadm raid setup that holds unrelated mount points (it's not /usr or anything like that).
