General Config Reference¶

fsid

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.

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 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.

Required:: No
Default:: 0

fatal signal handlers
