System information

Note: Determining the UUID and Label of a Particular Device
To determine the UUID and—if the device uses it—the label of a particular device, use the
bl ki d command in the following form:
bl ki d device
For example, to display information about /d ev/sd a3, type:
~]# bl ki d /d ev/sd a3
/dev/sda3: LABEL="home" UUID="34795a28-ca6d-4fd8-a347-73671d0c19cb"
TYPE="ext3"
18.2.1. Specifying t he File Syst em T ype
In most cases, mo unt detects the file system automatically. However, there are certain file systems,
such as NFS (Network File System) or C IFS (Common Internet File System), that are not recognized,
and need to be specified manually. To specify the file system type, use the mo unt command in the
following form:
mo unt -t type device directory
Table 18.1, “ Common File System Types” provides a list of common file system types that can be
used with the mo unt command. For a complete list of all available file system types, consult the
relevant manual page as referred to in Section 18.4.1, “Manual Page Documentation” .
