Sure you can. Modern BIOSs have options for booting from a secondary disk. If you setup LILO correctly then the most you should have to do is reconfigure the BIOS to use a different disk. Also if you have hot-swap hardware (say an entry level Dell 1650 PowerEdge server) then you can just unplug the failed disk and it'll boot from the remaining disk. One advantage of software RAID is the control you get over it. With hardware RAID you are often left wondering what the REAL status of your RAID device is, sometimes the communications between the RAID hardware and the OS fails and the OS thinks that it's all fine while it's really not (or the other way around). I've seen both on Solaris. > Its quite possible to fill /var and lock a server up to the point access is > not possible. Now I have to admit I have only seen this on Solaris, I Solaris is buggy then.

Bad assumptions are the cause of much lost time, money, and data. -- 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
