Hi! With todays Debian Sid/Experimental on my laptop this still doesn´t work right, I still have to add something like – I just recognized after I reinstalled initramfs-tools in a crude way after having messed it up by accidentally delete /var/lib/initramfs-tools (and then recognizing that it may have been easier to recover it than what I did):
merkaba:/etc/initramfs-tools/scripts/local-top> cat btrfs #!/bin/sh PREREQ="lvm" prereqs() { echo $PREREQ } case $1 in prereqs) prereqs exit 0; esac . /scripts/functions log_begin_msg "Initializing BTRFS RAID-1." modprobe btrfs vgchange -ay btrfs device scan log_end_msg Despite: merkaba:/boot> lsinitramfs initrd.img-4.7.0-rc2-tp520-btrfstrim+ | grep scripts | grep btrfs scripts/local-premount/btrfs scripts/local-top/btrfs So whatever local-premount/btrfs does it not sufficient for the BTRFS RAID on two LVs case. I may try again with dracut, but on my last attempt some years ago it also didn´t boot this out of the box. Thanks, -- Martin
