With some effort you can have grub boot from a RAID-1 (I won't try to explain how as I'm not an expert on booting, but it's something I've done before). You may decide to use non-RAID for /boot. After the kernel and the initrd have been loaded the initrd can setup RAID so you can have LVM on software RAID for the root file system (it's even supported in Anaconda). For a serious machine there are two ways of doing it. One is to have RAID for all file systems including the root file system. The other option is to have a kickstart configuration that completely describes the configuration of the system so that the machine can easily be reinstalled at a moment's notice. For an ideal server room you would have RAID on the system partitions and swap (so that a disk dying won't cause you to do any work at 3AM), RAID for data partitions (of course!), as well as having a dedicated server for kickstart that does DHCP and has NFS read-only shares containing every version of RHEL/Fedora that you run on your network. To do this right the kickstart server would be configured to assign a particular IP address and config file to each machine based on it's MAC address so reinstalling any server could be done by merely booting from a kickstart device (either CD or USB dongle). One thing I'm working on at the moment is a document on kickstart configuration for SE Linux. -- http://www.coker.com.au/selinux/ My NSA Security Enhanced Linux packages http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/~russell/ My home page -- fedora-selinux-list mailing list fedora-selinux-list@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/fedora-selinux-list
