totally different EG its hardware raid1 which you have to break manually in rescue mode via shh the SP you do it in the manager as it software raid1 raid0 I suggest a little reading to find your answers as its simpilicity itself

I recently got an EG AMD server and was trying to enable RAID0 using the above steps after booting to rescue mode.

I failed immediately at the first command:

1) tw_cli info c0

and it gave me this error

Error: (CLI:003) Specified controller does not exist.

and when I ran

tw_cli info


it gave

No controller found.
Make sure appropriate AMCC/3ware device driver(s) are loaded.


Anybody has any suggestions?

swas1982, derchris is correct, you haven't managed to successfully set up RAID0. I suggest you follow the guide above again.

Mate, I think you should really read up on how partitions and stuff is working.
There is nothing wrong with the disk.

You have a primary partition for root with 20 GB, and a extended one with the rest of 680. In there you have several logical partitions.

If you would have a Raid0 setup, with 2x750GB, then /dev/sda would be 1.5 TB.
This looks it is either still Raid1, or just a single disk.

Hi,
After following the steps as mentioned by slayer i have made it to RAID0 but i am still not able to access the other drive of 750gb.I have installed gparted and unable to locate the other drive as shown in the pic.I have attached the picture here.In the pic attached i can see the space of 679Gb but i am not able to access it.How do i get to use that unused space ?

Hope someone will help in this matter.

Thanx

Yeh RAID1 won't give you 1.5TB space from the two drives, that's RAID0.

RAID0 is striping so you can use the full 1.5TB, it does not duplicate any data.
RAID1 is mirroring so you have half the total space, as it duplicates data.

I think you are confusing yourself between the two configurations.

Thnx for the response Slayer,
Actually i want to have both the disk in RAID1,so i think i have to first break the hardware RAID1 as per the instructions given by you in another thread to make it RAID0.Then how do i get back making both the Disks into RAID1,so that i can use the total space provided i.e 1.5Tb.

Thanks

It should already be mirrored hence ovh advertising 2x750 in raid 1.
If it isint there then ovh are telling porkys but it will be.
Install gparted and check it,if you see it there then :-)

I see only one disk..when i do a fdisk it only shows the HDD size to be 750Gb..so how do i use both the HDD..i.e 1.5Tb

This is what i get when i do a fdisk

Disk /dev/sda: 750.1 GB, 750155325440 bytes
255 heads, 63 sectors/track, 91201 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00098ec5

Device Boot Start End Blocks Id System
/dev/sda1 * 1 1275 10241406 83 Linux
/dev/sda2 1276 90946 720282307+ 83 Linux
/dev/sda3 90947 91201 2048287+ 82 Linux swap / Solaris

How do i join both the disk and make it RAID1.

Thanx in advance

1. Open Up OVH Manager, select the dedicated E08 Server --> click services --> click netboot.

2. Once you have clicked netboot, another screen will show up, you choose the option "rescue pro", then enter in your contact details, then enter it.

3. Go back to services, and do a hard reboot to reboot the server.

4. Once the server is up, login to the server via ssh.

5. You then type the following commands in the following order:

1) tw_cli info c0
2) tw_cli maint remove c0 p0
3) tw_cli maint remove c0 u0
4) tw_cli info c0
5) tw_cli maint rescan
6) tw_cli maint createunit c0 rraid0 p0:1

6. You then exit ssh, go back to the manager, then click reinstall the OS.

Once the reinstall is complete, it should have the 2 hdd's in a raid-0 array.

In the above method if i change the Step6 to rraid1 is that fine to create a RAID1 HDD (mirroring) or it requires any other changes.

Hope to get some suggestions and ideas so that i can proceed ahead.

Thank You

But the eg best of already cums as raid 1 mirrored
So why change
