Running RH9. I have a PCI IDE controller with two 80GB harddrives attached, running as a RAID 1 array. One drive is the primary master, the other is the secondary master. One of the drives has developed a problem.
The RAID array is used only for file storage. I have a separate 40 GB HD on a motherboard IDE controller which has the OS loaded on it.
My questions are:
1. What utilities can I run to check each drive? How would I do it? Unmount, then ... , etc.
2. I would like to make sure that the problem is not with the PCI controller, so I would like to put both drives on the secondary channel of the motherboard controller as master and slave. What would I need to do to accomplish this?
3. If I have to replace the failed drive, what would I need to do? Can I just put in the new drive and the OS will take care of it?
I am a newbie at this stuff, and I setup the server about a year ago. I have forgotten many of the things I did to setup the RAID array. So thanks in advance for any help you can provide!
