removing a disk causes boot error

[danielruuth]

Hi, I'm totaly newb when it comes to disk and volume management in linux,
I'm attempting to install a new 1TB disk to remove the current 250GB disk, the system also has a 37GB disk.

What I did was that I added to new 1TB disk to the system with the LVM tool, I added it with a mountpoint of /storage2. Then I removed the old disk with the LVM tool and moved it's data to the remaining disks (the 37GB and the new 1TB) with the LVM tool.

Everything looks ok so far.

When I reboot with the old 250GB disk still in the system it's all fine. But when I remove it, the system won't reboot. I get to the point of where the fedora screen usually turns up.

The old disk had 2 partitions, the new one has only one, I'm starting to think there's something in there causing the issue? Can't load that big partion at boot or something?

As I said, complete newb when it comes tho theses things, can anyone help?

If I'm missing to fill in some details, just ask and I'll try to answere. I now has the old disk back in the system to be able to boot.

Anyone?

Fedora usually defaults to creating a separate boot partition which you probably don't have now, it was likely on the 250GB if it works when it is in and does not work when it is not. Can you log in to a terminal as root and run the command: fdisk -l (lower case Letter L) to post your partition information. I'm not familiar with LVM so hopefully someone else will see your post and advise.

Thanks for the quick reply,
here's what the readout says when I do a fdisk -l:

The whole story is that I before had two 250GB disks in raid 1 and now I'm attempting to have two of the new 1TB disk in raid. The raid was hardware controlled and will be again, for now it's turned off.

I see alot of "xx doesn't contain a valid partition table", guessing it's a part of the problem? Can I fixed that without having to remove the data on the new disk?
Otherwise I guess I need to add the data to the old disk somehow and partition the new disk somehow?

Your 250GB drive had/has the boot and Fedora system files? That would be the sdd drive. Are you keeping it attached? Do you have it set to first boot priority? If the answers to all the above are yes, it should boot. I doubt I'll be much help as I'm totally unfamiliar with LVM and/or RAID.
