Hi Petr,
use mdadm to rebuild the device. raidtools isn't included in CentOS 4.x anymore.
raidhotadd /dev/mdX /dev/${partition}
should be equivalent to
mdadm -A /dev/mdX /dev/${partition}

Phil.

-A is for assemble.

They might want tool called raidhotadd, but you really want tool called "mdadm". Try "man mdadm" and you'll find plethora of options to do what you need. Something like "mdadm /dev/md2 -a /dev/new-partition".
