haw can I resize my disk? I free some GB from windows but I need reallocate to FC4. How? Any help? TIA, Joao
You didn't say where the space was that you freed up, but there appears
to be some between cylinders 2558 and 3908 inclusive (about 10GB).
Here are a couple of approaches you could use to add this space to your
Linux system:
A: Add as a single filesystem.
You could create a new partition hda4 using "fdisk" and make that
partition type "Linux". You could then write a regular filesystem to
that partition using "mke2fs" and mount it somewhere like "/space", and
that would give you all that extra space under that directory. Fairly
straightforward, but the space might not be where you want it (e.g. /var
or /usr).
B: Add to LVM.
You create a new partition hda4 using "fdisk" and make that partition
type "Linux LVM". You then create a new LVM physical volume on that
partition using "pvcreate", add that volume to existing volume group
"VolGroup00" using "vgextend", then extend the size of the volume
containing your root filesystem (/dev/VolGroup00/LogVol00) using
"lvextend". You then need to resize your root filesystem, and you'll
need to boot from the rescue CD to do that since you'd be more than
doubling its size. Boot from the rescue CD, have it mount all of your
partitions and then unmount everything from /mnt/sysimage and below.
Then use "resize2fs /dev/VolGroup00/LogVol00". It'll probably tell you
to do an "fsck" first. Having done all this (see the manpages for each
command, and the LVM HOWTO), you'll end up with a system with an extra
10G for your root partition, which you can use wherever you need it.
