USB Stick Automounting on RHEL
USB sticks are not automounted on my nice Scientific Linux (RHEL) 5.x desktops. Why not?
gnome-volume-manager should do the mounting — but it's not running; gnome-volume-manager requires hald to be running, but it's not; in turn this requires the message bus, dbus.
- /etc/rc5.d/S22messagebus has failed — even though there exists /var/run/messagebus.pid with the appropriate time-stamp.
- /etc/init.d/messagebus start fails as /var/run/messagebus.pid exists, but /etc/init.d/messagebus restart works.
- Then /etc/init.d/haldaemon start works and gnome-volume-manager will start too — normally it starts as part of a gnome-session.
- Life is too short to figure out why the message bus won't start, though Googling suggests that some RedHat-based systems have problems with the message bus when LDAP authentication is enabled (owing to the order in which services are started being duff).
- Simply add a workaround — in addition to /etc/rc5.d/S33messagebus
we add
/etc/rc5.d/: S97messagebussimonh -> ../init.d/messagebussimonh
where messagebussimonh is a modified version of the original, in which start now does a stop first:start() { #### BEGIN ADDED : # echo -n $"Stopping system message bus: " killproc $servicename -TERM RETVAL=$? echo if [ $RETVAL -eq 0 ]; then rm -f /var/lock/subsys/$servicename rm -f /var/run/messagebus.pid fi # #### END ADDED. echo -n $"Starting system message bus: " if [ -x /bin/dbus-uuidgen ] ; then /bin/dbus-uuidgen --ensure fi daemon --check $servicename $processname --system RETVAL=$? echo [ $RETVAL -eq 0 ] && touch /var/lock/subsys/$servicename } stop() { echo -n $"Stopping system message bus: " ## we don't want to kill all the per-user $processname, we want ## to use the pid file *only*; because we use the fake nonexistent ## program name "$servicename" that should be safe-ish killproc $servicename -TERM RETVAL=$? echo if [ $RETVAL -eq 0 ]; then rm -f /var/lock/subsys/$servicename rm -f /var/run/messagebus.pid fi }
