Access folders on a btrfs SSD from Leap 15.1 running on ext4 fs

Hi all,

I have two SSD on my computer with dual boot.

  • Leap 42.3 on /dev/sda2
    with btrfs and - Leap 15.1 on** /dev/sdc2**
    with ext4.

I would like to copy** /srv/www/htdocs** from /dev/sda2 to /dev/sdc. I can’t boot Leap 42.3 atm so I have to access htdocs from Leap 15.1.

Can anybody show me a way I could do this?

You can try:

mount /dev/sda2  /mnt
mount --bind /dev /mnt/dev
mount --bind /proc /mnt/proc
mount --bind /sys /mnt/sys
chroot /mnt
mount -a
exit  ## exit from chroot environment

Those last three lines should mount all of the “btrfs” subvolumes. And, after doing that, you should be able to see your files at “/mnt/srv/www/htdocs”.

When done with your copying, you can use

umount -R /mnt

to unmount everything.

@nrickert thanks a lot! worked perfectly!
