Ceph Dependencies
|
|
|
|
|
=================
|
|
|
|
|
|
|
|
|
|
As a general rule, we recommend deploying Ceph on newer releases of Linux.
|
2014-06-12 19:48:29 +00:00
|
|
|
We also recommend deploying on releases with long-term support.

- **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.

|
|
|
|
2017-02-10 20:20:16 +00:00
|
|
|
For RBD, if you choose to *track* long-term kernels, we currently recommend
|
2020-10-07 22:21:28 +00:00
|
|
|
4.x-based "longterm maintenance" kernel series or later:
|
2017-02-10 20:20:16 +00:00
|
|
|
|
2019-06-19 08:28:33 +00:00
|
|
|
- 4.19.z
|
2018-04-17 16:50:04 +00:00
|
|
|
- 4.14.z
|
2020-10-07 22:21:28 +00:00
|
|
|
- 5.x

|
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.

Platforms

|
=========
|
|
|
|
|
|
|
|
|
|
The charts below show how Ceph's requirements map onto various Linux
|
|
|
|
|
platforms. Generally speaking, there is very little dependence on
|
2022-04-05 15:48:24 +00:00
|
|
|
specific distributions outside of the kernel and system initialization
|
2021-02-15 12:13:36 +00:00
|
|
|
package (i.e., sysvinit, systemd).

**For Centos 7 Users**

|
``Btrfs`` is no longer tested on Centos 7 in the Octopus release. We recommend using ``bluestore`` instead.
