Hi

I have a degraded array /dev/md2
=====================================================================
$ mdadm -D /dev/md2

=====================================================================


I need to add the 3rd partition, so I open documentation 
http://www.centos.org/docs/4/html/rhel-isa-en-4/s1-storage-rhlspec.html#S2-STORAGE-RAID-DAY2DAY
  (I know the RTFM ;-)

But in chapter 5.9.9.2.
they want tool caled "raidhotadd"

What was my wonder when it is not included in CentOS 4.3
=====================================================================
# yum provides raidhotadd
