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 entering

example# kill -HUP vold_pid

To tell vold to clean up and exit, the SIGTERM signal is used:

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 FALSE.

-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 provide status info to log file).

-d root-dir

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.

-f config-file

Specify an alternate configuration file. The default file is /etc/vold.conf.

-l log-file

Specify an alternate log file. The default log file is /var/adm/vold.log.

-L debug-level

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 programs which are called when events such as insert, notify, and eject occur:

VOLUME_ACTION

Event that caused this program to be executed.

VOLUME_PATH

Pathname of the matched regex from the vold.conf file.

VOLUME_DEVICE

Device (in /vol/dev) that applies to the media.

VOLUME_NAME

Name of the volume in question.

VOLUME_USER

User ID of the user causing the event to occur.

VOLUME_SYMNAME

Symbolic name of a device containing the volume.

VOLUME_MEDIATYPE

Name of the type of media (CD-ROM, floppy or rmdisk)

/etc/vold.conf

Volume Management daemon configuration file. Directs the Volume Management daemon to control certain devices, and causes events to occur when specific criteria are met.

/usr/lib/vold/*.so.1

Shared objects called by Volume Management daemon when certain actions occur.

/var/adm/vold.log

the default log file location (see the -l option for a description).

/vol

the default Volume Management root directory.
