mdadm error on Fedora Core 3

[andy]

Hi ,

I am testing on the steps on configuring the s/w raid on my local desktop which have 2 IDE 40GB plug-in with FC3 kernel 2.6.9-1.681_FC3. I downloaded the raidtools and mdadm and when I try to compile the mdadm and raidtools, I am getting the following errors :

Perhaps install the i386 rpm from here.

Thanks.The mdadm is installed but was receiving the following error when try to build up the array raid :

mdadm : SET_ARRAY_INFO failed for /dev/md0: Device or resource busy.

The server is initially setup with only 1 IDE device. Recently I just hooked up the 2nd IDE device ( the same brand and same capacity ) after plan to try out the s/w raid but have been no luck in configuring it. I have also read on the howto on http://www.faqs.org/docs/Linux-HOWT...RAID-HOWTO.html but still no luck .

Can some one help me on this ? What I am trying to do is to mirror the whole hardisk 1 to the second hardisk to create redundant so I can boot up using the second hardisk incase the 1st hdd fail.

Thanks,

You can not turn the drives to raid 1 while booted on one of the drives. The easy way is to reinstall your OS and create raid 1 device from the start.

It's possible to convert your install to raid from using the disk 1 of your install CD boot to linux rescue, but this better left for experts.
