ceph-detect-init – display the init system Ceph should use

Synopsis

ceph-detect-init [–verbose] [–use-rhceph] [–default init]

Description

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 --default is specified.

Options

--use-rhceph

When an operating system identifies itself as Red Hat, it is treated as if it was CentOS. With --use-rhceph it is treated as RHEL instead.

--default INIT

If the init system of the host operating system is unknown, return the value of INIT instead of failing with an error.

--verbose

Display additional information for debugging.

Bugs

ceph-detect-init is used by ceph-disk to figure out the init system to manage the mount directory of an OSD. But only following combinations are fully tested:

  • 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

Availability

ceph-detect-init is part of Ceph, a massively scalable, open-source, distributed storage system. Please refer to the Ceph documentation at http://ceph.com/docs for more information.
