After you do your base Centos install and 'yum update', do:
yum --enablerepo=centosplus update kernel
yum --enablerepo=centosplus install reiserfs-utils

Then reboot, and you should be able to mount the raid and add it to
/etc/fstab.

Ok but how does Centos recognise the ARRAY?
Is the Array's configuration stored some where?
SUSE uses raidtab.
The only raid type conf file on my other Centos boxes is /etc/mdadm.conf

So you mean to tell me I just have to make sure reiserfs is installed, then
just mount like this in fstab
/dev/md0             /home/tera           reiserfs   defaults              1
2
#mount -a
and bang everything in done?
Something tells me it can't be that easy.
