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.

|
|
- **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.

- **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.
|
|
|
|
