  1. Just a minute tidbit, as of March 1st, 2015, The Linux Foundation has replaced RAID with LVM in the LFCS Domains / Compentencies, so it would be fantastic if this article could be rewritten or replaced to reflect the slight change in test objectives. Thanks for your contributions, @Gabriel!

  2. @Bekzot,
    Thanks for bringing that to our attention. That is indeed a typo – I will notify the owner of the site to correct it ASAP.
    FYI, there is another typo here:
    # mdadm –create –verbose /.dev/md0 –level=5 –raid-devices=3 /dev/sdb1 /dev/sdc1 /dev/sdd1 –spare-devices=1 /dev/sde1
    (There should be no dot between the forward slash and the word dev – after the verbose directive)

    Thank you.

  4. I think here is a typo below:
    Restoring the backup from the image file

    # dd if=/system_images/sda.img of=/dev/sdc

    Should it be /dev/sda? or you intentionally restoring the data to /dev/sdc?

Got something to say? Join the discussion.
