==========================
General Config Reference
==========================
``fsid``
:Description: The filesystem ID. One per cluster.
:Type: UUID
:Required: No.
:Default: N/A. Usually generated by deployment tools.
``admin socket``
:Description: The socket for executing administrative commands on a daemon,
irrespective of whether Ceph Monitors have established a quorum.
:Type: String
:Required: No
:Default: ``/var/run/ceph/$cluster-$name.asok``
``pid file``
:Description: The file in which the mon, osd or mds will write its
PID. For instance, ``/var/run/$cluster/$type.$id.pid``
will create /var/run/ceph/mon.a.pid for the ``mon`` with
id ``a`` running in the ``ceph`` cluster. The ``pid
file`` is removed when the daemon stops gracefully. If
the process is not daemonized (i.e. runs with the ``-f``
or ``-d`` option), the ``pid file`` is not created.
:Type: String
:Required: No
:Default: No
``chdir``
:Description: The directory Ceph daemons change to once they are
up and running. Default ``/`` directory recommended.
:Type: String
:Required: No
:Default: ``/``
``max open files``
:Description: If set, when the :term:`Ceph Storage Cluster` starts, Ceph sets
the ``max open fds`` at the OS level (i.e., the max # of file
descriptors). It helps prevents Ceph OSD Daemons from running out
of file descriptors.
:Type: 64-bit Integer
:Required: No
:Default: ``0``
``fatal signal handlers``
:Description: If set, we will install signal handlers for SEGV, ABRT, BUS, ILL,
FPE, XCPU, XFSZ, SYS signals to generate a useful log message
:Type: Boolean
:Default: ``true``
