** Description changed: this is how the btrfs filesystem is laid out: root@manning:~# btrfs fi df / Data, RAID5: total=6.00GiB, used=2.93GiB System, RAID1: total=32.00MiB, used=16.00KiB Metadata, RAID1: total=512.00MiB, used=215.86MiB GlobalReserve, single: total=80.00MiB, used=0.00B root@manning:~# btrfs fi sh / Label: 'M-root' uuid: 365c6d42-8359-4239-ba1a-2b3a25f97ac2 - Total devices 3 FS bytes used 3.14GiB - devid 1 size 10.93GiB used 3.28GiB path /dev/sda3 - devid 2 size 10.93GiB used 3.50GiB path /dev/sdb3 - devid 3 size 10.93GiB used 3.28GiB path /dev/sdc3 + Total devices 3 FS bytes used 3.14GiB + devid 1 size 10.93GiB used 3.28GiB path /dev/sda3 + devid 2 size 10.93GiB used 3.50GiB path /dev/sdb3 + devid 3 size 10.93GiB used 3.28GiB path /dev/sdc3 device UUIDs are disabled in /etc/default/grub : GRUB_DISABLE_LINUX_UUID=true the relavant part of the generated grub.cfg looks like this: - echo 'Loading Linux 3.19.0-22-generic ...' - linux /vmlinuz-3.19.0-22-generic root=/dev/sda3 - /dev/sdb3 - /dev/sdc3 ro single nomodeset rootflags=subvol=@ - echo 'Loading initial ramdisk ...' - initrd /initrd.img-3.19.0-22-generic - + echo 'Loading Linux 3.19.0-22-generic ...' + linux /vmlinuz-3.19.0-22-generic root=/dev/sda3 + /dev/sdb3 + /dev/sdc3 ro single nomodeset rootflags=subvol=@ + echo 'Loading initial ramdisk ...' + initrd /initrd.img-3.19.0-22-generic when i re-enable UUIDs the generated grub.cfg comes out correct. + + btw. this is on Lubuntu 15.04 (Vivid Vervet)
