Hot disk change.

You could always use a temporary disk if the controller doesn't find the array when the original disk is at another connector. I would also do the dd from a live-CD to make sure no changes are done during the copy.
Connect temp/USB disk
Boot from live-cd
dd if=/dev/sda of=/dev/sdX
Shut down, replace disks and create new, larger array
Boot from live-CD
dd if=/dev/sdX of=/dev/sda

Thanks for all responses.
Now I see that I am in trouble.
I really cannot install everything from zero, it will take too long and
might not work.
I would like to know your opinion about the following procedure:
1 - Shutdown
2 - Remove both disks
3 - Plug both 2TB new disks and create a new virtual disk on the controller
4 - Plug one of the old 250GB disks in a separate SATA connector
5 - dd if=/dev/sdb of=/dev/sda (where sdb is the old disk and sda is the
new virtual disk)
6 - fstab, resize2fs, etc, etc...!
I really don't know if the OS will recognize and be able to read the old
disk plugged in another SATA connector.
Thanks in advance.
