Dear Dev1ers Unfortunately Debian still thinks partionable RAIDs are not worth to integrate into the installer. Like this it is still hard work to get a Devuan beowulf on a bootable partionable md raid1 and with UEFI not even possible according to my tries...
First of all I believe partitionable md raids are superior to "usual" mds which just span over partitions on different disks instead over the whole disk. If a disks dies and has to be replaced for the usual mds one needs to copy the partition table first using sfdisk -d /dev/workingdisk | sfdisk /dev/newdisk and install the boot loader on it, where as with partionable mds you can just hot add a new disk to the running raid using mdadm. Maybe that changed until today without me being aware of. I was able to set up a ascii on a partitionable raid0 including /boot using BIOS and DOS disk labels (with metadata 1.2). I failed miserably doing this using a GPT partition scheme and UEFI. Did someone manage to achieve this? Recently I retried using the beowulf installer, changed to the console to setup and format the md. The installer did not recognise the partitions are formatted and suggest refomatting them. Since I don't know if it pays attention to the stride-size and stripe-width options of Ext4 I don't want to let it do it. I then found out that it will install on it, when the raid is mounted in /target (you also need to bind mount /dev, /dev/pts, mount /sys and /proc as well). This definitively used to be different in earlier versions of the installer. Would it be hard to enhance the installer to fully support partitionable mds?
