The problem is this, that I don’t know which module to add and how. I think that I would have to chroot after installation and add it.
ls /etc/modprobe.d/modprobe.conf
"/etc/modprobe.d/modprobe.conf": No such file or directory (os error 2)
Follows the text from here
Registration in
/etc/fstab
If you don’t have an initrd, or your initrd doesn’t perform a btrfs device scan, you can still mount a multi-volume btrfs filesystem by passing all the devices in the filesystem explicitly to the mount command. A suitable
/etc/fstab
entry would be:/dev/sdb /mnt btrfs device=/dev/sdb,device=/dev/sdc,device=/dev/sdd,device=/dev/sde 0 0
Using
device
is not recommended, as it is sensitive to device names changing that is affected by the order of discovery of the devices. You should really be using a initramfs. Most modern distributions will do this for you automatically if you install their own btrfs-progs package.Using
device=PARTUUID=...
with GPT partition UUIDs would also work and be less fragile
Also talks here about modules
btrfs device scan
is used to scan all of the block devices under /dev
and probe for Btrfs volumes. This is required after loading the btrfs module if you’re running with more than one device in a filesystem.
