| 6 | ================= | |

| 8 | As a general rule, we recommend deploying Ceph on newer releases of Linux. | |
| 9 | We also recommend deploying on releases with long-term support. | |

| 14 | - **Ceph Kernel Client** | |

16 | If you are using the kernel client to map RBD block devices or mount |
| 17 | CephFS, the general advice is to use a "stable" or "longterm | |
| 18 | maintenance" kernel series provided by either http://kernel.org or | |
| 19 | your Linux distribution on any client hosts. | |

21 | For RBD, if you choose to *track* long-term kernels, we recommend |
| 22 | *at least* 4.19-based "longterm maintenance" kernel series. If you can | |
| 23 | use a newer "stable" or "longterm maintenance" kernel series, do it. | |

25 | For CephFS, see the section about `Mounting CephFS using Kernel Driver`_ |
| 26 | for kernel version guidance. | |
| 7c673cae | 27 | |
| 224ce89b | 28 | Older kernel client versions may not support your `CRUSH tunables`_ profile |
| 1e59de90 TL |
29 | or other newer features of the Ceph cluster, requiring the storage cluster to |
| 30 | be configured with those features disabled. For RBD, a kernel of version 5.3 | |
| 31 | or CentOS 8.2 is the minimum necessary for reasonable support for RBD image | |
| 32 | features. | |

| 36 | ========= | |

38 | The chart below shows which Linux platforms Ceph provides packages for, and |
| 39 | which platforms Ceph has been tested on. | |
| 40 | ||
| 41 | Ceph does not require a specific Linux distribution. Ceph can run on any | |
| 42 | distribution that includes a supported kernel and supported system startup | |
| 43 | framework, for example ``sysvinit`` or ``systemd``. Ceph is sometimes ported to | |
| 44 | non-Linux systems but these are not supported by the core Ceph effort. | |

| 71 | - **A**: Ceph provides packages and has done comprehensive tests on the software in them. | |
| 72 | - **B**: Ceph provides packages and has done basic tests on the software in them. | |
| 73 | - **C**: Ceph provides packages only. No tests have been done on these releases. | |
| 74 | ||
| 75 | .. note:: | |
| 76 | **For Centos 7 Users** | |
| 77 | ||
| 78 | ``Btrfs`` is no longer tested on Centos 7 in the Octopus release. We recommend using ``bluestore`` instead. | |
