How To Convert An ext3/ext4 Root File System To btrfs On Ubuntu 12.10 ext3 and ext4 file systems can be converted to btrfs. For non-root file systems, this can be done online (i.e., without reboot), while for root file systems we need to boot into some kind of rescue system or Live CD. This guide explains how to convert an ext3 or ext4 root file system into btrfs on Ubuntu 12.10 and how to roll back to ext3/ext4 again if desired.

Will this conversion wipe all my data i.e installed applications and files?

Hello,

Good tutorial, good job.

This command : "for fs in proc sys dev dev/pts; do mount --bind /$fs /mnt/$fs; done" does not work in Live CD of Ubuntu 16.04 on "sudo -s".

Have you an idea why ?

Thanks

Instead of editing /etc/grub.d/00_header

I read on internet there is this commands:

sudo grub-editenv create

sudo update-grub

sudo grub-install /dev/sda3

Note: I have the Manjaro bootlader on / partition, since i love to have my own master bootloader on MBR.

That avoids "error: sparse file not allowed".

At least on my Manjaro distro there is no "function recordfail" on that file, and the command fix the problem.

Also i had to type the command:

sudo mkinitcpio -P

Or else in enters in emergency shell at boot.

I type both commands after booting with "failsafe".
