Synopsis
|
|
========
|
|
|
|
| **ceph-detect-init** [--verbose] [--use-rhceph] [--default *init*]
|
|
|
|
Description
|
|
===========
|
|
|
|
:program:`ceph-detect-init` is a utility that prints the init system
|
|
Ceph uses. It can be one of ``sysvinit``, ``upstart`` or ``systemd``.
|
|
The init system Ceph uses may not be the default init system of the
|
|
host operating system. For instance on Debian Jessie, Ceph may use
|
|
``sysvinit`` although ``systemd`` is the default.
|
|
|
|
If the init system of the host operating system is unknown, return on
|
|
error, unless :option:`--default` is specified.
|
|
|
|
Options
|
|
=======
|
|
|
|
.. option:: --use-rhceph
|
|
|
|
When an operating system identifies itself as Red Hat, it is
|
|
treated as if it was CentOS. With :option:`--use-rhceph` it is
|
|
treated as RHEL instead.
|
|
|
|
.. option:: --default INIT
|
|
|
|
If the init system of the host operating system is unkown, return
|
|
the value of *INIT* instead of failing with an error.
|
|
|
|
.. option:: --verbose
|
|
|
|
Display additional information for debugging.

Bugs
|
|
====
|
|
|
|
:program:`ceph-detect-init` is used by :program:`ceph-disk` to figure out the init system to manage the mount directory of an OSD. But only following combinations are fully tested:
|
|
|
|
- `upstart` on `Ubuntu 14.04`
|
|
- `systemd` on `Ubuntu 15.04` and up
|
|
- `systemd` on `Debian 8` and up
|
|
- `systemd` on `RHEL/CentOS 7` and up
|
|
- `systemd` on `Fedora 22` and up
|
|
