Ceph Dependencies
|
|
=================
|
|
|
|
As a general rule, we recommend deploying Ceph on newer releases of Linux.
|
|
|
|
Linux Kernel
|
|
------------
|
|
|
|
- **Ceph Kernel Client:** We currently recommend:
|
|
|
|
- v3.6.6 or later in the v3.6 stable series
|
|
- v3.4.20 or later in the v3.4 stable series
|
|
|
|
- **btrfs**: If you use the ``btrfs`` file system with Ceph, we recommend using
|
|
a recent Linux kernel (v3.5 or later).
|
|
|
|
glibc
|
|
-----
|
|
|
|
- **syncfs(2)**: For non-btrfs filesystems such as XFS and ext4 where
|
|
more than one ``ceph-osd`` daemon is used on a single server, Ceph
|
|
performs signficantly better with the ``syncfs(2)`` system call
|
|
(added in kernel 2.6.39 and glibc 2.14). New versions of Ceph (v0.55 and
|
|
later) do not depend on glibc support.
|
|
|
|
|
|
Platforms
|
|
=========
|
|
|
|
The charts below show how Ceph's requirements map onto various Linux
|
|
platforms. Generally speaking, there is very little dependence on
|
|
specific distributions aside from the kernel and system initialization
|
|
package (i.e., sysvinit, upstart, systemd).

Notes
|
|
-----
|
|
|
|
- **1**: The default kernel has an older version of ``btrfs`` that we do not
|
|
recommend for ``ceph-osd`` storage nodes. Upgrade to a recommended
|
|
kernel or use ``XFS`` or ``ext4``.
|
|
|
|
- **2**: The default kernel has an old Ceph client that we do not recommend
|
|
for kernel client (kernel RBD or the Ceph file system). Upgrade to a
|
|
recommended kernel.
|
|
|
|
- **3**: The default kernel or installed version of ``glibc`` does not
|
|
support the ``syncfs(2)`` system call. Putting multiple
|
|
``ceph-osd`` daemons using ``XFS`` or ``ext4`` on the same host will
|
|
not perform as well as they could.
|
|
|
|
Testing
|
|
-------
|
|
|
|
- **B**: We continuously build all branches on this platform and exercise basic
|
|
unit tests. We build release packages for this platform.
|
|
|
|
- **I**: We do basic installation and functionality tests of releases on this
|
|
platform.
|
|
|
|
- **C**: We run a comprehensive functional, regression, and stress test suite
|
|
on this platform on a continuous basis. This includes development branches,
|
|
pre-release, and released code.
