``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.

|
: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``
