Dear Phil, > http://wiki.centos.org/HowTos/SoftwareRAIDonCentOS5 > > Comments and corrections please. Sorry Phil. I personally cannot accept this HowTo at current state. There is also some cute documentation available in the Deployment Guide. You wrote: 'Some controllers claim to be RAID but require Windows drivers to function, similar to winmodems.' This is not true. Some controllers make use of OS functionality. This is not dependent to Windows. You wrote: 'Booting will only work from non-RAID or RAID1 partitions. RAID0 or RAID5 will not work.' This is only true if you wish to have the boot partition (/boot/) reside on a RAID parition. In this case it must be on a RAID1 partition. Also, in your scenario it does not make much sense to split /boot and may cause confusion, as it's not necessary on a RAID1. You wrote: 'Disable any hardware-based RAID in the motherboard or RAID controller BIOS ' Why that? I have some systems where I combine hardware- and softraids. This may be the case on fakeraid controllers. ...skipping...someone else could take care... You wrote: After installing a new kernel, repeat Section Three. It should be possible to apply a similar approach to a /boot on RAID1, or to a / on RAID1 without a /boot. Why should someone want to use dd to mirror a / partition on an active RAID1 ?
