### Btrfs storage driver on CentOS 7 and RHEL 7
**Deprecated in Release: v23.0.0**
The `btrfs` storage driver on CentOS and RHEL was provided as a technology preview
by CentOS and RHEL, but has been deprecated since the [Red Hat Enterprise Linux 7.4 release](https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/storage_administration_guide/ch-btrfs),
and removed in CentOS 8 and RHEL 8. Users of the `btrfs` storage driver on CentOS
are recommended to migrate to a different storage driver, such as `overlay2`, which
is now the default storage driver. Docker 23.0 continues to provide the `btrfs`
storage driver to allow users to migrate to an alternative driver. The next release
of Docker will no longer provide this driver.
