Tino and Jens,
# fdisk -l (with comments about what is what)
/dev/sda1 1 243 1951866 82 Linux swap /
/dev/sda2 * 244 729 3903795 83 Linux (/boot)
/dev/sda3 730 3161 19535040 83 Linux (/)
/dev/sda4 3162 30318 218138602+ 83 Linux (/var)
I'm not that worried with the partition table because I can just delete
the partition, create it again with the new size and use resize2fs to
resize the file system. Usually I do that with virtual machines and it
works, shouldn't be different with a real hardware, right!?
I'm really worried to know it Linux would be able to read the old disk
connected on a different SATA port.
Cupertino, I got worried with your solution because I don't know is I
can expand the virtual disk and things like that, I don't have much
expertise with RAID controllers. And if something goes wrong (read: if I
make something wrong), I will loose everything. I do have backup and
everything, but I prefer a short downtime.
