NAME
fsmpm - Xsan File System Port Mapper daemon
SYNOPSIS
fsmpm [host-ip [debug [sync [diskscan [extHA]]]]]
DESCRIPTION
The FSM Portmapper is a server daemon residing on each Xsan File System
client and server. It registers an RPC identifier to the system's
portmap daemon. The fsmpm publishes a well known port where the Xsan
File System Manager (FSM) daemons can register their volume name and
port access number. All clients then talk to their local FSS port map-
per to discover access information for their associated service. This
process runs in the background and is started at boot time. It is
enabled or disabled (along with the volume) via chkconfig(1M) or init.d
using the acfs key word.
OPTIONS
Apple Internal Use Only - contact support before adding or modifying
command line arguments to fsmpm. Changes from the defaults may result
in intermittent or total failure of Xsan. Options may change abruptly
between releases.
host-ip
The IP address used to access this host. The default is to try
to resolve the system's hostname to an address. If set to 127.1,
no nameserver will be used and no heartbeats will be sent.
(default: no hostname)
debug Bitmask specifying which debug messages to print. (default: 0)
sync The name of a file whose creation is used to detect when the
fsmpm has successfully started. (default: no file)
diskscan
How often (in seconds) to rescan for changed paths. 0 disables
the disk scan. (default: 0)
extHA External HA mode prevents the fsmpm from automatically starting
FSMs in the fsmlist, as well as disabling calls for elections.
1 enables external HA mode; 0 disables it. (default: 0)
NOTE: Defaults specified with '--'.
FSNAMESERVERS
The fsmpm reads the file /Library/Preferences/Xsan/fsnameservers to
establish file system name servers for the Xsan file system services.
This list is used to coordinate the whereabouts of Xsan file system
servers.
A name server list must be established on each client that has Xsan
installed so that all clients can discover the location of the Xsan FSM
servers. It is important that this list is consistent across the SAN.
Inconsistent fsnameservers configuration may result in the inability
for some clients to find a file system service. See fsnameservers(4)
for specifics of the file format.
FSMLIST
The fsmpm is responsible for launching the FSM daemon(s). If
/Library/Preferences/Xsan/fsmlist exists then the fsmpm reads from the
list file and starts the FSM daemons that are specified. If no
/Library/Preferences/Xsan/fsmlist file exists then the fsmpm tries to
launch the FSM daemon for the volume named default. See fsmlist(4) for
specifics of the file format.
ENVIRONMENT
These variables are for use by Apple support personnel only.
FSMPM_MAX_LOGFILES
Controls the number of old nssdbg.out log files that will be saved
by fsmpm when the current log file reaches its maximum size. The
default is 4.
FSMPM_MAX_LOGSIZE
Controls the maximum size that the nssdbg.out file can grow to
before a new log file will be started. The value is a number fol-
lowed by an optional suffix (K for Kilobytes, M for Megabytes, G for
Gigabytes), or the string unlimited, indicating that the file can
grow without bound. The default is 1M and the minimum is 64K.
