[H] Ghosting a striped RAID setup

2006-04-19 Thread Thane Sherrington (S)
I've got a machine with a screwed up Windows install on a striped 
RAID setup (four disks, ranging from 4.3GB to 80GB.)  What's the best 
way to back this up to another drive so I can recover data after I 
reinstall Windows?  Ghost shows it as four separate disks, but in a 
striped RAID isn't the data spread over all the disks?

What version of Ghost? Are you booting to a floppy? Apparently the 
raid drivers aren't being loaded otherwise ghost should see one big 
disk so you probably aren't loading ghost via Windows. Have you tried 
running Ghost from a BartPe or XpPe disk to see if that ghost can see 
only one big disk?

Thanks.  I have no idea why I didn't think of that, but I appreciate 
you not suffixing your comments with you moron.  :)

Follow up question.  Windows shows the RAIDed drives as four separate 
drives, each the size of the physical drive.  Acronis shows them as 
five separate Promise 1+0 Stripe/RAID 0 - I've never used RAID 0 - is 
it reasonable to assume that the drives are striped, but that there 
is a C: drive that has the Windows and programs on it, and then a D, 
E, and F that have data?  If this is the case, and all I want to do 
is reformat the drive holding Windows and reinstall Windows, then I 
assume I just have to figure out which of the drives holds Windows 
and make a backup of that drive (in case there is data on it.)  Am I right?

You should find out all you need to know by going to the Promise 
Properties in the DM. My Windows Explorer shows striped drives as one 
drive  I have to look at the SIL properties to tell that they are 2 
separate drives. If is not the case for you then I'd say the Promise 
Raid Arrays were never setup especially since you state the 4 
separate drives that shows up in Windows [Explorer or DM] is the same 
physical size as the drives. I also have a NVraid that I've never 
setup an array on yet have individual SATA drives off of it which 
sounds to me like what you have except maybe your drives are PATA 
which shouldn't make any difference.

Don't know if it is an apples to oranges thing but:

I have 8 drives on an LSI MegaRaid Controller.
In order to set up the config I wanted - I created 4 striped sets of 2 (Raid
0), Then I paired 2 sets into a Raid 1. So I wound up with 2 raid arrays in
an equivalent Raid 10 configuration.

When bringing them into windows I created four logical drives on 1 array and
1 logical drive on the second array.

Nothing at the windows level lets me see an individual drive. Now with Power
Console Plus an raid management tool from LSI I can see the individual
drives and the arrays. But this tool is for management of the drives in the
array. No other software in my systems sees past the Arrays. The only real
difference at the windows level, drive management under Windows shows my
array with 1 logical drive as a Dynamic drive with a gold bar above it, the
array that is broken up into 4 logical drives is shown as a basic drive just
like the single drives normally found in a system. 

And just in case you are wondering why I configured this way - speed for the
primary reason, and I am happy to say that this is a much more robust
configuration than my previous Raid 5 config. Also the raid 10 is more
redundant - the degree to which depends upon which drives decide to die
first.

But I have had this config for more than 6 months I am very happy with it.
The only drawbacks are cost. In a R5 with 8 drives @160g each you would have
roughly 960GB with R10 you wind up with 640GB. But since drives are only
about @120 each it's not an absolute Killer. Anyway, it works for me. lol
