General Config Reference

admin_socket

The socket for executing administrative commands on a daemon, irrespective of whether Ceph Monitors have established a quorum.

type:

str

default:

/var/run/ceph/$cluster-$name.asok

pid_file

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:

str

chdir

The directory Ceph daemons change to once they are up and running. Default / directory recommended.

type:

str

daemonize

fatal_signal_handlers

If set, we will install signal handlers for SEGV, ABRT, BUS, ILL, FPE, XCPU, XFSZ, SYS signals to generate a useful log message

type:

bool

default:

true

max_open_files

If set, when the Ceph Storage Cluster starts, Ceph sets the max open FDs at the OS level (i.e., the max # of file descriptors). A suitably large value prevents Ceph Daemons from running out of file descriptors.

Type:: 64-bit Integer
Required:: No
Default:: 0
