Hello all,
I'm hoping someone can help me.
I've just upgraded by dedicated server with OVH from 9.04 to 10.04 and it now refuses to boot with the error
"kernel panic unable to mount rootfs on unknown block 2,0"
With OVH you must use their custom kernel, but this has been installed and seems to boot thus far, but fails at above.
OVH also recommend adding a dev line to fstab, which I've done: http://travaux.ovh.net/?do=details&id=4154
I'm now at a loss as what to do, as it seems the kernel can't see the hard drives, yet when I boot up in rescue mode, I can mount all the drives fine.
Any help gratefully received!
