Software Raid related question
Hi for testing purpose , i am trying to create software raid .
i am following this article : http://www.linuxtopia.org/online_books/centos5/centos5_administration_guide/centos5_s1-raid-config.html
the last picture of this article, and my raid pertition is almost similier
like i have create LVM in /dev/md1
now, i remove 2nd hardrive, so the OS should boot up from one first hardrive, is not it ?? (Raid is for that - it was my undestadning)
but it was unable to find out LVM and it will not boot, so i had to attache 2nd hardrive again
did i do any thing wrong for my configuration ??
NOte : About Raid my understanding was, if one hardrive goes down , still OS will run from another heardrive , and i will swap the faulti one with another one
Or is this just work for scsi , not ide ??
