RAID 0 and Multiple Partitions?

[igiveup]

OK, I posted this in the Operating System forum, but I think this might be the better forum for this question.

Does anyone know if you can create multiple partitions under RAID 0? From what I know of RAID as long as the partitions are the same size it seems like it wouldn't matter. The RAID controller should see the drives as being a single drive, no matter what the partition tables are. Anybody? Thanks in advance!!!

The partitions shouldn't even have to be the same size. Like you said the RAID controller treats the two drives as one. If you set up a partition, half of it would be on each drive and when ever you read/write from/to that partition the RAID controller takes care of the rest.

As far as partitioning goes, the software (fdisk, PM, etc.) will think there's only one big drive to carve up anyway you like.

I've got three partitions on my RAID 0 array as well...no problemo!

I believe you are under the impression that you have to fdisk and format each individual HDD before you create the array. Actually this is not so. You will create the array first and then fdisk (and create partitions as you wish) and format.

Yeh my RAID0 config, was partitioned using fdisk, though, I don't know if it was one of those computer annomolies, but the first time I rebooted and loaded the OS the partition didn't show. I did fdisked again, and this time made sure to do a cold boot after the partition/extended logical DOS partitioning,and of course designating a boot sector, and then it worked ok.

partition is based on volume's. one hd can = one volume, many hd can = one volume.


once you've defined a volume, you can partition that volume anyway you want it.

i think your under the impression that 1 HDD = 1 Volume. not true. it was just convenient before to think of it that way because you weren't raiding. even w/o raid, you can still define more than one hdd as one volume but you take a performance hit. when you use raid 0, it defines 2 or more hdd as 1 volume. because your stripping, however, instead of lining up your hdd as in making master and slave hdd one volume, you get an increase in performance.

anyway, that's what i've been lead to believe.

Actually, I am not under any impression. I have no idea what the truth is, but it seemed that it wouldn't matter as to the drive setup since the RAID controller does all the work. Am I right? Seems like thats what everybody is saying.
