libblockdev-3.0.4

libblockdev の概要

libblockdev is a C library supporting GObject Introspection for manipulation of block devices. It has a plugin-based architecture where each technology (like LVM, Btrfs, MD RAID, Swap,...) is implemented in a separate plugin, possibly with multiple implementations (e.g. using LVM CLI or the new LVM DBus API).

注記

LFS や依存パッケージが本ブックに示す最新安定バージョンでなかった場合には、BLFS 開発版においては、パッケージのビルドや処理実行が適切に行われないことがあります。

パッケージ情報

libblockdev の依存パッケージ

必須

GLib-2.78.3

推奨

cryptsetup-2.6.1, gobject-introspection-1.78.1 (GNOME にて必要), keyutils-1.6.1, libbytesize-2.10, libnvme-1.7.1, LVM2-2.03.23

任意

btrfs-progs-6.6.1, GTK-Doc-1.33.2, mdadm-4.2, parted-3.6, volume_key, ndctl, targetcli (for tests)

libblockdev のインストール

以下のコマンドを実行して libblockdev をビルドします。 

./configure --prefix=/usr      \
            --sysconfdir=/etc  \
            --with-python3     \
            --without-escrow   \
            --without-gtk-doc  \
            --without-lvm      \
            --without-lvm_dbus \
            --without-nvdimm   \
            --without-tools    &&
make

The test suite requires targetcli, which is not a part of BLFS.

root ユーザーになって以下を実行します。 

make install

コマンド説明

--without-escrow: This switch allows building libblockdev without volume_key installed.

--without-lvm --without-lvm_dbus --without-tools: The combination of these switches allows building libblockdev without parted-3.6 installed. Remove it if you've installed parted-3.6 and wish to build the lvm-cache-stats or vfat-resize utilities, or wish libblockdev to support logical volumes.

--without-btrfs --without-mdraid --without-tools: The combination of these switches allows building libblockdev without libbytesize-2.10 installed. The --without-mdraid option will break UDisks-2.10.1, so don't use it unless you really know what you are doing.

--without-crypto: This switch allows building libblockdev without cryptsetup-2.6.1 or keyutils-1.6.1 installed. This switch will break UDisks-2.10.1, so don't use it unless you really know what you are doing.

--without-dm --without-lvm --without-lvm_dbus --without-mpath: The combination of these switches allows building libblockdev without LVM2-2.03.23 installed. The --without-dm and --without-mpath options are not in the instructions provided by the book because LVM2-2.03.23 is required for cryptsetup-2.6.1 and cryptsetup-2.6.1 is a recommended dependency of libblockdev anyway.

--without-nvme: This switch allows building libblockdev without libnvme-1.7.1 installed. This switch will break UDisks-2.10.1, so don't use it unless you really know what you are doing.
