Fix size of disk in partition table

[Heiner E. Lennackers]

Hi,

when i change the size of the disk where my linux lives (by cloning it to a large disk or migrating the raid unit) fdisk always says i have the old disk size. I know that partition magic will fix this when booting with it and then the additional disk space can be used e.g. for additional partition.
My question is now: Is there a linux tool which can do the same, even better without booting the system?

You could boot from a gparted live CD.

I don't know about better, but there's a tool called "parted" that manipulates partitions.

gparted = graphical interface to parted

as for automated fixes, it doesn't do it, but you could possibly script something around it..

be aware that parted comes with a warning for every action. it can do the wrong thing..
