Package: initramfs-tools
Verston 0.137
I just installed a system using the testing netinst cd image [Debian GNU/Linux bullseye-DI-alpha2 _Bullseye_ - Official Snapshot amd64 NETINST 20200315-11:07]
After install, I converted my btrfs root partition to a raid1 profile, with the understanding that the Debian installer doesn't support that out of the box yet. The problem I've had is that while the initramfs does a btrfs device scan before trying to mount the root file system, when the mount command in the initramfs executes, the second device in the btrfs filesystem goes unfound.
If I run a btrfs device scan from the initramfs shell i can mount the root file system just fine and continue to boot into the installed operating system.
If i add the script lines from the pre-mount btrfs scripts to the local_mount_root() in /usr/share/initramfs-tools/scripts/local right before the mount command is executed the initramfs works correctly. I have a hunch this isn't the right solution, despite the fact that it works and I know that the btrfs device scan in the pre-mount btrfs script does in fact get executed. I'm simply unsure what the correct solution actually is with this.
if [ -x /bin/btrfs ]
then
modprobe btrfs ||:
# If asked to be quiet, show only errors
[ "${quiet}" = "y" ] && exec >/dev/null
/bin/btrfs device scan
fi
