vold - Volume Management daemon to manage CD-ROM and floppy,
ZIP/JAZ, and DVD-ROM devices
/usr/sbin/vold [-n] [-t] [-v] [-f config-file] [-l log-file]
[-d root-dir] [-L debug-level]
The Volume Management daemon, vold, creates and maintains a
file system image rooted at root-dir that contains symbolic
names for floppies, CD-ROMs and other removable devices. The
default root-dir is set to /vol if no directory is specified
by the -d option.
vold reads the /etc/vold.conf configuration file upon
startup. If the configuration file is modified later, vold
must be told to reread the /etc/vold.conf file. Do this by
example# kill -HUP vold_pid
To tell vold to clean up and exit, the SIGTERM signal is
example# kill -TERM vold_pid
where vold_pid is the process ID of vold.
The following options are supported:
-n Never writeback. Volume Management updates media
labels with unique information if labels are not
unique. This flag keeps Volume Management from
changing your media. The default setting is
-t Dump NFS trace information to the log file. The
default setting is FALSE.
-v Provide lots of status information to the log
file. The default setting is FALSE (do not pro-
vide status info to log file).
Specify an alternate root directory. The default
location is /vol. Setting this will also cause
other Volume Management utilities to use this as
the default root directory.
Specify an alternate configuration file. The
default file is /etc/vold.conf.
Specify an alternate log file. The default log
file is /var/adm/vold.log.
Change the level (verbosity) of debug messages
sent to the log file. The range is 0 to 99 where
0 is nothing and 99 is everything. The default
level is 0.
vold sets the following environment variables to aid pro-
grams which are called when events such as insert, notify,
and eject occur:
Event that caused this program to be executed.
Pathname of the matched regex from the vold.conf
Device (in /vol/dev) that applies to the media.
Name of the volume in question.
User ID of the user causing the event to occur.
Symbolic name of a device containing the volume.
Name of the type of media (CD-ROM, floppy or
Volume Management daemon configuration file. Directs
the Volume Management daemon to control certain dev-
ices, and causes events to occur when specific cri-
teria are met.
Shared objects called by Volume Management daemon when
certain actions occur.
