User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/mdadm
Kernel versions in series 4.1 and 4.2 have a broken RAID implementation. Use a kernel with version above 4.2.4.
Enable the following options in the kernel configuration and recompile the kernel, if necessary. Only the RAID types desired are required.
Device Drivers ---> [*] Multiple devices driver support (RAID and LVM) ---> [CONFIG_MD] <*> RAID support [CONFIG_BLK_DEV_MD] [*] Autodetect RAID arrays during kernel boot [CONFIG_MD_AUTODETECT] <*/M> Linear (append) mode [CONFIG_MD_LINEAR] <*/M> RAID-0 (striping) mode [CONFIG_MD_RAID0] <*/M> RAID-1 (mirroring) mode [CONFIG_MD_RAID1] <*/M> RAID-10 (mirrored striping) mode [CONFIG_MD_RAID10] <*/M> RAID-4/RAID-5/RAID-6 mode [CONFIG_MD_RAID456]
Install mdadm by running the following commands:
If you wish to run the tests, ensure that your kernel supports RAID
and that a version of mdadm is not already running, and issue:
make test and then,
root user: ./test --keep-going --logdir=tests-logs
--save-logs. Some tests fail for unknown reasons.
Now, as the
make everything: This optional target creates extra programs, particularly a statically-linked version of mdadm and also versions of mdassemble. These all need to be manually installed.
--keep-going: Run the tests
to the end, even if one or more tests fail.
Defines that the directory where tests logs are saved.
--save-logs: Instructs the
test suite to save the logs.
Optional comma separated list of tests to be executed (all tests,
if this option is not passed).
