Title: Adding hard disks and I-Bays
Post by: D.Garrett. on February 02, 2002, 08:07:22 AM

I was wondering if you could help me with a problem I have.

I have E-Smith 5.1.2 installed on a 20gb drive. No probs. :)
I need more space though and have two 60gb IBM drives to add.

I'm just a newbie, but have managed to add, partition (ext2) and mount the drives to load to folders in a temp i-bay. I did chmod the folders and they work fine through the i-bays.

This is fine for a fixed purpose, two 60gig folders in one i-bay. This is not really what I need though.

I wanted to be able to create many i-bays in each of the new drives and manage them with the server manager as normal.

How would I go about this and where can they be mounted to allow the server manager to control them as normal I-Bays?

All this could be avoided if E-Smith allowed the use of Raid 0, I would just make one big array....

Thank-you for any help you may offer.

D.G.

Mount it as /home/e-smith/files/ibays.

Won't I get a conflict if I mount both extra drives at the same mount point?

Remember there are two IBM 60 gb drives to add to the existing 20gb drive, which has the install on it.

You can only mount one drive at any one mount point. Either get a larger drive, or use raid.

Sorry, but there is a way to mount extra drives and use them for more -bays.

Unfortunately, I have done it myself, but can't remember how to do it.

Just had a search in the forums - look for 'Mounting new hard drives' Make sure you choose 'All dates' when searching.

The answers are all there. I'm no genius but I made it work !

Title: My Solution.
Post by: D.Garrett on February 04, 2002, 06:20:05 AM

Thanks for the help guys :)

The solution I came up with was to install E-Smith 5.1.2 on a 2gb drive /dev/hda.

I then added two 60gb drives and made primary partitions on them, /dev/hdb1 and /dev/hdc1 .

I made a striped array (raid 0) with the two drives, /dev/hdb1 + /dev/hdc1 = /dev/md0 .

To finish off, I mounted /dev/md0 at /home/e-smith/files/ibays . Manage as usual from server-manager, sweet!

If you want to add a bit more to the mod, like I did. Use hdparm (I used version 4-6.2) to trick it up a bit.

I'm getting an Avg buffered disk read of 41Mb/s from the 120Gb array. Any good?

It has worked out well and is a cheap solution for people who need lots of space for the I-Bays, IMHO.

Note: Have a good back-up plan and stick to it. Raid 0 + disk failure = bye bye I-Bays.

Hi

I want to do the same as you...but i know very little about linux in general. Im glad you have a solution and i was wondering if you could talk me through it. I have 2X 6gb drives that i want to add to an existing server built on a 7gb drive. I want them setup exactly as you have so i can set different ibays with different policies etc.

Any help would be greatly appreciated
