Hi Oliver, It's not the same thing :) Although they work, and do the same, the installer CD & mdadm needs to support it. The specific appliance that I want to install, doesn't support RAID 10, so I need to install RAID 1 + RAID 0, i.e. setting 2x RAID 1 mirrors, and then stripe then in RAID0 - but once the first 1 mirrors are setup, I can't stripe them.
I've seen people use LVM to add them to one volume, but the installer doesn't see to like that either
Hmmm... 'specific appliance'.
This doesn't sound like you are installing CentOS. This makes it *really* hard for us to help you since we have absolutely no idea what you are actually doing. ;)
A) What are you actually doing?
B) Do you have to have RAID10 during install or is it sufficient that you can build a data 'drive' after install?

heh, I was a bit hesitant to say what it is, but it's fine I guess - seeing as my previous post dealt on the matter of NAS devices :)
I'm installing Openfiler 2.3, which looks very very similar to the CentOS installer. My reason for RAID 1+0 (like I said it doesn't support RAID10) is for the higher level of redundancy & speed, and I would like to utilize the drives to their max,
I've setup the /boot on sda1 & sdc1 (100MB each) on RAID 1, and then configured sda2, sdb2, sdc2, sdd2 as 4GB swap each (no RAID), then the remainder on sda3, sdb3, sdc3 & sdd3 as 2x RAID 1 mirrors - i.e. sda3 & sdc3 on /dev/md2 & sdb3 & sdd3 on /dev/md3.
Yet, I can't create another RAID, i.e. /dev/md4 of md2 & md3 combined, nor can I tell the LVM setup to span md2 & md3 into the same volume. So, now I'm stuck.
