Install Issues

[tnats]

Hey folks,

I'm having all sorts of issues trying to install an Ubuntu server with software raid 1 on two disks.

I first installed 7.04 and created a raid 1 system using two disks with no problem. It was very easy. Then, I realized the software I wish to install (plesk) requires 6.06 so I burned the .iso and installed. After the reboot, grub gave me the famous: "file not found" error. I tried to go in and set /dev/sdb to be bootable (ie. grub, device /dev/sdb; root(hd0,0); setup(hd0) but it said the partition does not exist. I played with it for a few more hours and gave up.

Next, I threw in a CentOS disk because I can get software raid running on that with no problems but after the install, I get a "Grub error 17".

Is there something I'm missing here? In each install, I chose manual partitioning and wiped out any previous partitions and file systems. So, do I need to clear out my MBR on this machine? It can't be this hard to get this done. Thanks for any advice/tips you can give me. I'm all google'd out and have tried many suggestions from those sites.

Ubuntu may detect the wrong drive sometimes. Try this to reinstall grub correctly http://ubuntuforums.org/showthread.php?t=224351&highlight=reinstall+grub

Tom,
I had a similiar error and it basically resulted from Ubuntu thinking that hd0 was really hd1, so I had to manually edit my /boot/grub/menu.lst file and then run "sudo grub-install hd0" all over again...

Definitely check the above link for troubleshooting grub. I think your system will work fine, you just have to make sure grub is looking in the right places for a kernel to boot.

Also, why can't you use 7.04? Is there a specific version of that program only available on 6.06?

Cheers,
David

Ok, I figured it out. I reinstalled and made / sda1 and swap sda2 and it works fine now. I had it the other way around before. All the instructions I've seen say nothing about this.

I do understand that any machine will read sda1 first so it makes sense to me now, just don't know why I didn't see it posted any where.

Thanks for the help.
