Hello the list! My Debian (wheezy am464, upgraded from an original squeeze install) system started complaining yesterday that one of my hard disks is about to fail. I suspect it suffered damage in the earthquake that recently hit Japan (I'm in Tokyo) and has been quietly deteriorating since.
Anyway the disk concerned is a 1TB disk on which is mounted /opt, so I feel I should be able to replace it without major hassle. I have already backed it up fully to NAS. The only issue is that I don't have enough spare power connectors on my PC's power supply to attach both the new and the old disks at the same time. What I want to know is how can I remove the current drive from the filesystem so I can remove it physically without sending the machine into a tailspin? I have only ever set up the mapping of disk partitions to mount points at installation time, never afterwards, and so am not sure what to do. I am thinking the procedure will be something along the lines of: 1) modify my computer's mount settings such that /opt is part of the root filesystem instead of a separate mount point (HOW? manual edit of /etc/fstab or something more sophisticated?) This will cause me to lose access to everything on the old disk which is OK because it's all backed up and there is nothing there that's critical to the running of the machine. 2) Power down the machine and remove the old disk, attach the new disk. 3) bring up the machine, partition and format the new disk. (is the tool for this fdisk?) 4) modify the machine's mount settings to go back to mounting /opt on the new disk (HOW?) 5) restore everything I want in /opt back from the backup. Even assuming I'm on the right lines, I don't know how to do steps 1 and 4 and am not totally confident about how to do 3, so would appreciate any advice.
