20.12.5 Recovering an Original Non-root File System

Caution

If you roll back a conversion, you will lose any changes that you have made to the btrfs file system. Make a back up of the changes that you want to reapply to the restored file system.

To roll back the conversion of the file system and recover the original file system:

  1. Unmount the btrfs file system and all of its snapshots and images in the reverse order from which you originally mounted them. 

    # umount temp_mountpoint2
# umount temp_mountpoint1/image
# umount mountpoint

  2. Roll back the conversion. 

    # btrfs-convert -r device

  3. Mount the original file system. 

    # mount -t extN device mountpoint
