btrfs-progs-5.19
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 LVM2-2.03.16 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 --disable-documentation &&
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-8.45.
Before running tests, build a support program:
make fssum
To test the results, issue (as the root
user):
pushd tests
./fsck-tests.sh
./mkfs-tests.sh
./cli-tests.sh
./convert-tests.sh
./misc-tests.sh
./fuzz-tests.sh
popd
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.
Install the package as the root
user:
make install
Command Explanations
