I made the 2nd partition BTRFS (copy, mkfs.btrfs, copy-back) on my PC and changed ny rootfstype to btrfs in cmdline.txt. But I'm getting
$this->bbcode_second_pass_code('', 'Raspberry PI – PANIC: VFS Unable to mount root fs on unknown-block ')
Did I miss some steps?
$this->bbcode_second_pass_quote('', 'E')dit:
I also added a line to /etc/fstab
