The following section describes new removable media features in the Oracle Solaris release.
For a complete listing of new Oracle Solaris features and a description of Oracle Solaris releases, see Oracle Solaris 10 8/11 What’s New.
Solaris 10 1/06: 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
For a description of these properties, see the vold(1M).
Solaris 10 1/06: Removable media management is improved. Previously, vold did not create device links for removable devices that contain no media. Now, device links are properly created for devices that contain no media, similar to the following:
lrwxrwxrwx 1 root root 28 Jun 13 13:09 /vol/dev/aliases/cdrom0 -> /vol/dev/rdsk/c2t2d0/nomedia
Now, you can use the cdrw and rmformat commands to list devices that have no media when vold is running.
You can revert back to the previous vold behavior by changing the following support nomedia entry in the /etc/vold.conf file as follows:
Then, restart vold. For more information, see vold.conf(4).
In addition, vold is now hot-plug aware. This improvement means that if you insert removable media, the media is automatically detected and mounted by vold. There should be no need to restart vold manually to recognize and mount a file system from any removable media device.
If you are using a legacy or non-USB diskette device, then you might need to issue the volcheck command before vold can recognize the media.
If the media is detected, but for some reason, is unmounted, then you'll need to run the following commands:
# volrmmount -i rmdisk0
Before you hot-remove a removable media device, eject the media first. For example:
# eject rmdisk0
