You actually can add raid to the hard drive where you have the OS installed in most modern distros. Its a bit tricky in the old ones. The old ones require that you install to a different hard drive, then set up a software raid table, then move the system to the raid array, then edit the fstab, then reboot. This is a lot of work. In systems after about RH 7.1, the graphical install allows you to put / on a software raid array. Usually what you'll want to do, however, is make one partition on the first drive be the /boot partition (non-raid) just to make kernel configuration easier. Then put / on the raid array. You can get some of the performance bonuses from raid 0/5 by putting /usr, /home, /bin, /opt and whatever on separate drives if you have a big enough system. -Eric Hattemer > > Brian > > > > > > -----Original Message----- > > From: [EMAIL PROTECTED] > > [mailto:[EMAIL PROTECTED] Behalf Of Eric Hattemer > > Sent: Thursday, August 15, 2002 2:53 PM > > To: [EMAIL PROTECTED] > > Subject: Re: [luau] Software RAID (Donation of Oracle 9i Linux) > > > > > > In litteral terms, you can do software raid on linux with 1 HD and two > > partitions.
