Installation of LVM2

Install LVM2 by running the following commands:

SAVEPATH=$PATH                  &&
PATH=$PATH:/sbin:/usr/sbin      &&
./configure --prefix=/usr       \
            --exec-prefix=      \
            --enable-cmdlib     \
            --enable-pkgconfig  \
            --enable-udev_sync  &&
make                            &&
PATH=$SAVEPATH                  &&
unset SAVEPATH

The tests use udev for logical volume synchronization, so the LVM udev rules and some utilities need to be installed before running the tests. If you are installing LVM2 for the first time, and do not want to install the full package before running the tests, the minimal set of utilities can be installed by running the following instructions as the root user:

make -C tools install_tools_dynamic &&
make -C udev  install                 &&
make -C libdm install

To test the results, issue, as the root user:

make check_local

Other targets are available and can be listed with make -C test help. The test timings are very dependent on the speed of the disk(s), and on the number of enabled kernel options.

The tests do not implement the “expected fail” possibility, and a small number of test failures is expected by upstream. More failures may happen because some kernel options are missing. For example, the lack of the dm-delay device mapper target may explain some failures. Some tests are flagged “warned” if thin-provisioning-tools are not installed. A workaround is to add the following flags to configure:

     --with-thin-check=    \
     --with-thin-dump=     \
     --with-thin-repair=   \
     --with-thin-restore=  \
     --with-cache-check=   \
     --with-cache-dump=    \
     --with-cache-repair=  \
     --with-cache-restore= \

Some tests may hang. They can be removed if necessary, for example: rm test/shell/lvconvert-raid-reshape.sh. The tests generate a lot of kernel messages, which may clutter your terminal. You can disable them by issuing dmesg -D before running the tests (do not forget to issue dmesg -E when tests are done).

Now, as the root user:

make install
