Expand a xen disk image.

[Mad Professor]

Hello all, I need to expand a 15GB xen disk ".img" to 50GB, it's got centos as the guest O/S.

I've been googling and there are alot of results but I'm still having trouble.

I don't remember if I used the default LVM partition scheme or if I did a FS. In fdisk it says linux partition but that's it.

I did the dd and cat method but fsck is complaining like usual.

I dd a file called tempfile and the append it using cat tempfile >> my.img then did resize2fs -f but it error out with "Bad Magic number on super block."


Other methods seem more complicated then need be.

Any help or direction would be appreciated.

Have you tried giving it a go with Parted Magic or any other LiveCD?

I apologize for the vague post, I was writing it before work, then I was late anyways.

This is what want I'm trying to do. I have a guest operating system running on xen host, it uses a 15GB xen virtual disk and it's running out of space. I need to expand the virtual disk to at least 50GB, I'm not trying to image a hard-drive or clone one.

makes sense?
