vold(1M) System Administration Commands vold(1M)NAMEvold - Volume Management daemon to manage removable media devices
SYNOPSIS
/usr/sbin/vold [-n] [-t] [-v] [-f config-file] [-l log-file] [-d root-
dir] [-L debug-level]
DESCRIPTION
The Volume Management daemon, vold, creates and maintains a file system
image rooted at root-dir that contains symbolic names for removable
media devices. These devices include CD-R, CD-RW, floppies, DVD, and
USB and 1394 mass storage 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. Accomplish this rereading by entering:
example# svcadm refresh volfs
To tell vold to clean up and exit, enter:
example# svcadm disable volfs
To reenable:
example# svcadm enable volfs
To specify options (see OPTIONS):
example# svccfg
svc:> select volfs
svc:/system/filesystem/volfs> listprop vold/*
vold/config_file astring
vold/log_debuglevel count 0
vold/log_file astring
vold/log_nfs_trace boolean false
vold/log_verbose boolean false
vold/never_writeback_label boolean false
vold/root_dir astring
svc:/system/filesystem/volfs> setprop vold/never_writeback_label=true
svc:/system/filesystem/volfs> exit
# svcadm disable volfs
# svcadm enable volfs
vold is hotplug-aware for USB and 1394 mass storage devices, thus there
is no need for stopping and restarting vold. It is recommended to
eject(1) the "media" before hot-removing a device. The eject command
unmounts any filesystems mounted from the media, making it safe to
remove the device. (Note that all USB and 1394 devices, regardless of
whether they contain removable media, are treated like removable media
devices).
OPTIONS
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 loca‐
tion 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.
ENVIRONMENT VARIABLESvold 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 vol‐
ume.
VOLUME_MEDIATYPE Name of the type of media (CD-ROM, floppy or
rmdisk)
FILES
/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 dae‐
mon 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.
