Raid 1 on Fedora core 2


Hello...

I have a motherboard with a raid controller on board. I have the sil 3112A SATA PCI Controller. My question is, how do I get this to work on my Fedora system?

Thanks
M46

all right you are going to have to re install fedora core 2
then chouse custom when it asks what type of install you want to do
config grub if you have to
then when the prompt comes up on the screen that asks you if you want to auto partition or manual select manual and both drives then tell it to delete all partitons
all right when you get to diskdroid the manual partitioner
alright now i want you to create a new partition it will ask what kind select swap your going to want to make it twice the size of your ram
now make another partion make it ext3 filesystem and for the mount point make it /boot make it the same size as your swap but make sure its on the opposite drive that the swap is on
now for the raid in the top right corrner you will see a button that says ether raid or software raid click and make partion as big as your drive can hold do the same to the other drive
now click that raid button agin now click set up raid it will ask you what mount point make that / now it will ask what type of raid now i recomend raid0 because it is twice as fast as raid1 so use raid zero and dont mess with the other options then click next then just pick what packages you want to install irecommend going to the bottom and selecting complete
then it will format your harddrives and install fedora then when its done click next then reboot
then start fedora for the first time go through the settings and run fedora
AND CONGRATS YOU GOT RAID ITS REALLY QUITE EASY

Excellent help! I was using DiskDruid to manually partition my drives but I wasn't too sure about it because the 2 drives I wanted to use were in a raid hardware set, so I was unsure whether to put them in a software raid set. Thanks for the clarificaton.

I want to use this computer as a server (mail server for a IT charity), and thought RAID 1 would be good, as I can recover data if the hard drive (or anything else) fails. Why would RAID 0 but good for a server? RAID 0 is stripping, isnt it?

I really really really really appreciate your help +rep

raid 0 is better for servers because it is faster and for me it is a lot faster install

I still sont understand...

The main drawback of RAID 0 is the increased risk of suffering data loss. For a given disk capacity you have more hardware to go wrong compared with a single unit, so it is likely to fail more regularly. If one disk develops a serious fault the whole array is trashed.

this is seriously confusing me aaaaarrrrrrrrrgggggggggghhhhhhhhhhhhhhhhhhhhhhhhh

thats if you drop the hd or get a virus but suprise there are no viruses on linux and i seriously doubt that you will drop your hd
but even if one fails if you reinstall they should be fine

Are those hd's ata66 ata100 ata133 or sata?

what is the interfase of that mouse (usb or P/S2)?
agp or pci or intergrated graphics?

- 512 mb pc133 ram
- ata133
- logitec infrared mouse, ps2
- agp graphics card

(i had no problems using the same fedora on a non-raid setup with the same system)

"grep /proc/mdstat" shows the partitions, wich are perfectly mirrored (marked by [2/2])

i may be wrong, but aren't those instructions on making a SOFTWARE raid? i have a motherboard with no raid controller and i made a software raid like that (not quite the same instructions, but similar, i actually put my swap on the raid device).

the original poster has hardware raid (i.e. a raid controller on his motherboard), something tells me that utilizing that would be different...

That is right. But I have a feeling that my raid controller is not compatible with fedora as of yet. I am not using software raid at the mo, as it would be a waste of the hardware controller.
