Hello All,
In the not too distant future I will be commissioning a new CentOS (5.4?) box with 4 identical SATA drives. I'd like to set them up as RAID 1+0 for speed and redundancy. I've read the RHEL 5 deployment guide on raid setup and it seems to cover the basics of software raid pretty well, but doesn't cover 1+0. Does anyone have a reference for that kind of configuration?
I'd also like to have two virtual domains, one for CentOS and one for Debian. any suggestions for setup docs for that kind of arrangement?
TIA.
Dave

There was a discussion on this list about that a few weeks ago..
I think the easiest route if you want software raid 1+0 is to use a combination of RAID 1 software and then use LVM for striping.
Myself I would use a 3Ware hardware RAID card.

virtual domain? Not sure what a virtual domain is, do you mean sub domain ? What is a virtual domain? If it's a KVM(as in virtualization) term then don't worry I can't help there, vmware user here.

Hello
The current anaconda doesn't allow you to select RAID10, however, RAID10 does work if you configure such an array manually.

Read the virtualization docs.
Best regards,

raid1+0. Not raid10. That is a module implementing a non-standard raid that Neil Brown calls raid10 and this md module is not included in the installation initrd although it is available afterwards I think.
