How do I boot a system root on a multidevice BTRFS subvol?
Hello,
recently I installed a distribution I want to look at via chroot into a
btrfs subvolume on a multidevice btrfs.
Now I tried to boot this, the kernel command line in GRUB looks as
follows so far:
/kernel-2.6.29-rc7-git3 root=/dev/sdb7 rootfstype=btrfs
rootflags=device=/dev/sda1,subvol=archroot
This gives "VFS: cannot find sdb7 or bad block", like it would when
trying to mount via fstab without -o device=foo
The fstab line for / looks like:
/dev/sdb7 / btrfs device=/dev/sda1,subvol=archroot 1 1
Is this possible already, or am I doing something wrong?
Many thanks in advan...
