How to find which raid is configured(without restart)

pinga123 · 08-30-2010, 05:47 AM

Is there a way to find the raid type without restarting the machine?

I m using linux operating system.

Code:

cat /proc/mdstat

@vinaytp - is that only for soft or hard raid?

It is for Software RAID.

Its a hardware raid.

An important thing to have missed out of your question because I was curious as I too have a hardware driven raid and this does not work.

Firstly, thanks for -p to less ... hadn't used it before

I find that both tell me about my RAID hardware (which is cool), but neither seem to tell me, unless I missed it, what type of raid I am running?

As an example, my laptop returns the following:

Code:

lshw | less -p RAID

Usually the manufacturer of the RAID controller will provide a software with which you can view/control the hardware RAID configuration. I would suggest going this route if possible.

You're welcome

I suppose that is onboard raid controller.

What's your motherboard?

smilemukul · 08-30-2010, 09:39 AM

Also how can I see the faulty hardware raid through CLI

Any solution will be appreciated
Thanks

My machine in this case is a Dell XPS 1730 (or M1730 depending on where you look). The raid is turned on in the BIOS and then it has interface
for setting it up when you boot. So I know I can get the details then, I was just curious (as per the question) if it were possible to tell
whilst the machine is running.

I do notice that when my machine starts I often see an error message flash up about dm-0 or dm-1 from inotify. Not really sure what they are about as they
flash very quickly and I do not seem to see it in a log anywhere

I believe motherboard specification should contain all information about RAID.

To me this would seem to imply there is no raid on the machine you ran it on.
