Kernel
Configuration
Enable the following option in the kernel configuration and
recompile the kernel:
File systems --->
<*/M> Btrfs filesystem support [CONFIG_BTRFS_FS]
In addition to the above and to the options required for LVM2-2.03.11 and
reiserfsprogs-3.6.27, the following
options must be enabled for running tests:
File systems --->
[*] Btrfs POSIX Access Control Lists [CONFIG_BTRFS_FS_POSIX_ACL]
[*] ReiserFS extended attributes [CONFIG_REISERFS_FS_XATTR]
[*] ReiserFS POSIX Access Control Lists [CONFIG_REISERFS_FS_POSIX_ACL]
Installation of btrfs-progs
Install btrfs-progs by running the
following commands:
./configure --prefix=/usr \
--bindir=/bin \
--libdir=/lib \
--with-pkgconfigdir=/usr/lib/pkgconfig &&
make
Note
Some tests require grep built with perl regular expressions. To
obtain this, rebuild grep with the LFS Chapter 8 instructions
after installing PCRE-8.44.
To test the results, first disable one test that fails and prevents
the other ones to run:
mv tests/fsck-tests/012-leaf-corruption/test.sh{,.broken}
To test the results, run (as the root
user):
make -j1 -k test
Note
If the above mentioned kernel options are not enabled, some tests
fail, and prevent all the remaining tests to run, because the
test disk image is not cleanly unmounted.
Two tests fail for unknown reasons in the test-libbtrfsutil section. Tests
take a very long time, and it may be interesting to run only part
of them. Running tests only in one directory can be done with
make TEST=<DIR>
test.
Install the package as the root
user:
make install &&
ln -sfv ../../lib/$(readlink /lib/libbtrfs.so) /usr/lib/libbtrfs.so &&
ln -sfv ../../lib/$(readlink /lib/libbtrfsutil.so) /usr/lib/libbtrfsutil.so &&
rm -fv /lib/libbtrfs.{a,so} /lib/libbtrfsutil.{a,so} &&
mv -v /bin/{mkfs,fsck}.btrfs /sbin
