9 Converting an Ext File System to a Btrfs File System
You can use the btrfs-convert
utility to convert an ext
file system to a Btrfs file system. The utility preserves an image of the original file system
in a snapshot named extN_saved
, such as
ext4_saved
. With this snapshot, you can roll back the conversion, even if
you have changed the btrfs
file system.
Note that you can't convert a root file system or a bootable partition, such as
/boot
, to Btrfs.
Note:
The conversion to Btrfs isn't supported on the Arm (aarch64) platform. If you're running Oracle Linux on the aarch64 platform, you can migrate data from one file system to another file system.
