- \section{Overview}
- I occasionally expand hdds. When this is done, sometimes I have to move partitions around, for example, changing a 1,2,5 (2 and 5 being extended partitions) to a 1,2, which I did for my main documentation machine. When this occured, there were a few gotcha's which I will try to note here.
-
- \section{Notes}
- Here's a rough outline of what happened.
-
- I had a 1,2,5 (the 2nd partition being an empty transition partition from primary to extended type) partition table. 1 was root, 5 was swap.
-
- It was a 40GB HDD. I decided to expand it to an 80GB HDD.
-
- First, I used clonezilla, and did a standard disk to disk. Everything went without a hitch.
-
- Then I needed to resize the partitions
- \subsection{resize partitions}
- I've always done this with fsck. Apparently parted once\footnote{They removed this, and replaced it with something different. removing backwards compatibility is a sin in software. They have sinned.} had a command named resize and some guides online still talk of it, as if it will work. It doesn't. It was removed. Don't waste time with parted.
-
- Fsck, essentially, you delete all the partitions, then add them as you want, IF you have a root partition that is 1, with everything. \footnote{If you split up the partitions, you will need to image the partitions and copy them differently.} I always use a single root partition. Simple. No need to complicate a desktop os. So for 1,2,5, I delete all partitions, then add 1, with an additional 40G in fsck.
-
- +80G in this case is what I did.\footnote{Perhaps I should've done +70G to stay under the 80G of an actual 80GB hdd.}
-
- Then add the swap after.
-
- mkswap the swap. resize2fs the root partition (it may ask you to e2fsck -f first, so do that if necessary). That's easy.
-
- However, here's the trap. You aren't done. You need to edit not only fstab, but also a few other places.
-
-
- \subsection{Things to edit:}
-
- \begin{itemize}
- \item fstab
- \item /etc/initramfs/conf.d/resume (may be optional if you don't suspend)
- \item update-grub
- \item update-initramfs -u -all
- \item grub-install /dev/sda
- \item grub-install /dev/sda1
- \end{itemize}
-
- You add the new blkid of the new swap (if it's new) to the conf.d resume. My grub-install /dev/sda1 errored out, but I think it was the /dev/sda one I needed to redo. Do both just in case. Also make sure to do an update-initramfs -u -all. And you probably already remembered about update-grub but that should probably be done as well.
-
- It's easy to miss one of these, and if you do, you will be loaded into grub. If you load manually in grub with:
-
- \emph{linux = /boot/vmlinuz...}
-
- \emph{initrd = /boot/initrd...}
-
- \emph{boot}
-
- Then in my case, you will end up in an initramfs that can't find the fstab. So then chroot into the hdd, and run the steps above.
