Mounting RAID partition on startup

**linuxuser21** · April 30th, 2009

I have followed this tutorial and successfully made my IDE hard drive mount on startup with correct permissions. (Thanks Psychocats!) I've tried to do the same for the RAID partition. Only, cciss/c0d0p8 instead of /sda and I just get errors.

Code:

mkdir: cannot create directory `/cciss/c0d0p8': No such file or directory

&

Code:

mount: mount point /cciss/c0d0p8 does not exist

mkdir: cannot create directory `/cciss/c0d0p8': No such file or directory

I'm sure you can do this... where is /cciss?

If it already exist then move there and then create /c0d0p8.

It's in /dev.
instead of a normal hard drive: /dev/sda, it's /dev/cciss/c0d0p8.

I must admit I'm not sure what you have... raid, I don't see it. If it's raid then it's hardware raid, from a card or the like, and you need a driver to mount the array first, before you can see it.

What is this /dev/cciss, please?

Anyway, make a mountpoint somewhere on your boot drive, e.g., /home/raid then you can mount the partition as needed.

Code:

sudo mkdir /home/raid

sudo mount /dev/cciss /home/raid

That might do what you wish.

Yes, it's hardware RAID. If you look at my signature, I have 3 72.8gb SCSI drives with a HP Smart Array 641 controller (set up as RAID 5). Of course this means that the computer picks it up as 1 logical drive. In the screenshot I have attached, you can see that I have it partitioned it so I have a 90gb partition by itself. (I didn't just leave the rest as a /home partition. I wanted to have it as extra space for my personal files or possibly other distros, OSs, ect., in the future.)
I have Ubuntu installed on the array and everything works as it should. My focus right now is to make the 90gb partition mount on startup with the correct permissions as I was able to do with the IDE HDD. I am able to mount it by clicking on it under the "Places" menu or from the sidebar.

It worked!
For future reference, I used these codes:

Code:

sudo mkdir /disk

sudo mount /dev/cciss/c0d0p8 /disk

In fstab:

Code:

/dev/cciss/c0d0p8 /disk ext4 defaults 0 0

Code:

sudo chown -R <username>:<username> /disk

sudo chmod -R 777 /disk

Thank you fjgaude!

Great! So much to consider with each setup... few are the same. I had no knowledge of your HP controller, or whatever.

Anyway, we all learn something new each day.
