What's New in Removable Media?

The following section describes new removable media features in the Solaris release.

For a complete listing of new Solaris features and a description of Solaris releases, see .

Changes and Improvements to Removable Media Management

Oracle Solaris 11 Express: Previous features for managing removable media have been removed and replaced with services and methods that provide better removable media management.

The following new features are available:

The following features are removed:

Backward Compatibility

The following features provide backward compatibility with previous Solaris removable media features:

Mounting and Unmounting Removable Media

Most commands that begin with vol* are removed in this release. A modified version of rmmount and a new rmumount command are available to mount and unmount removable media.

These commands can be used to mount by device name, label, or mount point. For example, to mount an iPod:

% rmmount ipod

For example, to unmount the file systems on a DVD:

# rmumount cdrom
cdrom /dev/dsk/c0t6d0s5 unmounted
cdrom /dev/dsk/c0t6d0s0 unmounted

For more information, see rmmount(1M).

Mounting and Unmounting Diskettes

You can use the existing volcheck command to manually poll diskettes and mount them if a new diskette is detected.

If you manually reformat diskette after it is connected to the system, HAL is not automatically notified. Continue to use the volcheck command to notify the system and attempt to automount a new file system on a diskette.

Ejecting Removable Media

As in previous Solaris releases, use the eject command to unmount and eject removable media. However, the following eject options are available:


Forces the device to eject even if the device is busy.


Displays paths and nicknames of devices that can be ejected.


A CD-ROM tray close command is provided to the device. Not all devices support this option.

For example, to eject by its volume label:

% eject mypictures

As in previous Solaris releases, you might need to issue the volcheck command before using the eject command to eject a diskette.

For more information, see eject(1).

Customizing Removable Media Management

For most customizations that were available in the vold.conf and rmmount.conf files, you will need to either use Desktop Volume manager preferences or modify the .fdi files.

Disabling Removable Media Features

You can disable some or all removable media features in this release:

vold is Managed by the Service Management Facility (SMF)

Oracle Solaris 11 Express: The volume management daemon, vold, is now managed by the Service Management Facility (SMF). This means you can use the svcadm disable command to disable the following new volfs service, if appropriate:

# svcadm disable volfs

You can identify the status of the volfs service by using this command:

$ svcs volfs
STATE          STIME    FMRI
online         Sep_29   svc:/system/filesystem/volfs:default

For more information, see smf(5).

You can use the svccfg command to display and to set additional vold properties. For example, you could temporarily enable vold logging to help troubleshooting a problem. For example:

# svccfg
svc:> select system/filesystem/volfs
svc:/system/filesystem/volfs> setprop vold/log_debuglevel=3
svc:/system/filesystem/volfs> exit
# svcadm disable volfs
# svcadm enable volfs

You can also use the svccfg command to display a listing of settable vold properties.

# svccfg
svc:> select volfs
svc:/system/filesystem/volfs> listprop vold/*
vold/config_file            astring  
vold/log_debuglevel         count    3
vold/log_file               astring  
vold/log_nfs_trace          boolean  false
vold/log_verbose            boolean  false
vold/root_dir               astring  
vold/never_writeback_label  boolean  false
svc:/system/filesystem/volfs> exit
