OS Recommendations
====================
Ceph Dependencies
=================
As a general rule, we recommend deploying Ceph on newer releases of Linux.
We also recommend deploying on releases with long-term support.
Linux Kernel
------------
- **Ceph Kernel Client**
If you are using the kernel client to map RBD block devices or mount
CephFS, the general advice is to use a "stable" or "longterm
maintenance" kernel series provided by either http://kernel.org or
your Linux distribution on any client hosts.
For RBD, if you choose to *track* long-term kernels, we recommend
*at least* 4.19-based "longterm maintenance" kernel series. If you can
use a newer "stable" or "longterm maintenance" kernel series, do it.
For CephFS, see the section about `Mounting CephFS using Kernel Driver`_
for kernel version guidance.
Older kernel client versions may not support your `CRUSH tunables`_ profile
or other newer features of the Ceph cluster, requiring the storage cluster to
be configured with those features disabled. For RBD, a kernel of version 5.3
or CentOS 8.2 is the minimum necessary for reasonable support for RBD image
features.
Platforms
=========
The chart below shows which Linux platforms Ceph provides packages for, and
which platforms Ceph has been tested on.
Ceph does not require a specific Linux distribution. Ceph can run on any
distribution that includes a supported kernel and supported system startup
framework, for example ``sysvinit`` or ``systemd``. Ceph is sometimes ported to
non-Linux systems but these are not supported by the core Ceph effort.

- **A**: Ceph provides packages and has done comprehensive tests on the software in them.
- **B**: Ceph provides packages and has done basic tests on the software in them.
- **C**: Ceph provides packages only. No tests have been done on these releases.
- **1**: Testing has been done on Centos 9 starting on version 17.2.8 for Quincy.
Container Hosts

- **H**: Ceph tests this distribution as a container host.
.. note::
**For Centos 7 Users**
``Btrfs`` is no longer tested on Centos 7 in the Octopus release. We recommend using ``bluestore`` instead.
.. note:: See the list of QAed container hosts in the Ceph repository here:
