Introduction to UDisks

The UDisks package provides a daemon, tools and libraries to access and manipulate disks and storage devices.



Development versions of BLFS may not build or run some packages properly if dependencies have been updated since the most recent stable versions of the book.

Installation of UDisks

Install UDisks by running the following commands:

./configure --prefix=/usr        \
            --sysconfdir=/etc    \
            --localstatedir=/var \
            --disable-static     &&

To test the results, issue: make check. A more thorough test can be run with make ci. You must first create the directories /var/run/udisks2 and /var/lib/udisks2, and the optional python modules should be present.

Now, as the root user:

make install

Command Explanations

--disable-static: This switch prevents installation of static versions of the libraries.

--enable-gtk-doc: Use this parameter if GTK-Doc is installed and you wish to rebuild and install the API documentation.

Configuring UDisks2

Config Files

/etc/udisks2/mount_options.conf and /etc/udisks2/udisks2.conf

Configuration Information

The default configuration of UDisks2 assumes ntfs-3g is used to mount NTFS filesystems. If the wrapper script for in-kernel NTFS3 driver (recommended in the ntfs-3g-2022.5.17 page) is used instead, create a configuration file for UDisks2 compatible with NTFS3 to allow mounting NTFS filesystems:

cat > /etc/udisks2/mount_options.conf << "EOF"


Installed Programs: udisksctl and umount.udisks2
Installed Library: libudisks2.so
Installed Directories: /etc/udisks2, /usr/include/udisks2, /usr/libexec/udisks2, /usr/share/gtk-doc/html/udisks2, and /var/lib/udisks2
