Hi everyone.
I have a question/problem and would like any advise or corrections in my approach.
I have a Dell T3400, latest available A11 Bios, 4GB RAM and Intel Core Duo Q6600 (I think) processor. I would like to use the onboard RAID controller (Intel Storage Matrix) to use 2*1TB WD Green.
The box will have CentOS 6.4 and will be used as a file server, local DNS server and potentially a development web server.
So, I put in two 1TB disks, used the CTRL+I to access the Raid config to setup the RAID 1.During this process I found that 1 disk was faulty.
What I did was I unplugged this disk "built a RAID 1 array with only 1 disk".
!!!This is the crux of my question!!!
I went on to install centOS 6.4 on a 'degraded' RAID 1 config and all installed OK and the server is running (on reboot I have to hit F1 to continue as it complains that 1 disk is missing)
So, getting to the question:
How can I get a secondary disk rebuilt?
Further details:
I've purchased another 1TB disk (faulty sectors found on it and getting replacement in a couple of days!) and plugged it into SATA port 1 (not 0) and restarted the box.
The RAID config boot screen shows both disks BUT 1 says it's in a degraded state and one in 'Non-raid'.
When I press CTRL+I to enter the config screen both disks are visible (1 raid 1 not). Now I try to create a volume and it says something like 'no enough room....)
coming back to the question: Did I bugger up the initial raid setup by running with only 1 disk? and hoping that I could just plug another disk in later and the raid controller would just rebuild the new disk?
The disks are identical (except for the bad sectors in the new one).
My options here seem to be:
.... dump the current array
.... rebuild a new array with the two discs
or ?????
I've heard that the Intel Storage matrix is not real raid... should I not bother?
Any information here could say me some time but I'm assuming that:
You cannot create a RAID 1 array with 1 disk and hope that later the controller will detect a new disk and rebuild it...
