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.

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). A suitably large value prevents Ceph Daemons from running out of file descriptors.
