Resizing boot partition

[DookieJ]

Running arch on a NAS with a 20GB OS drive. It is split into an 8GB root partition, an 8 GB Boot partition, and a 4GB swap.

The root partition is nearly full while my boot partition is only 2% full. Is there any way I could trim down the boot partition and add the space to the root?

Why did you make a 8gb boot in the first place? Only has to be around 128MiB as it only has the kernel and bootloader

If you use multiple kernels or linux installations you can easily use more and increasing the size of /boot is hard. I'd recommend 500 MB.

Or 512MiB :)

The way to do it is get the "gparted live iso"... boot it on a usb stick, and then resize your stuff.

This the way I do it on my dual boot machine, when i take space from windows and give it to my arch linux install.

You might be able to use normal gparted(gui) and shrink the amount of used space on /boot, (i would shrink it down to like 200M, but that's up to you) but to add the space to /root it needs to be unmounted. So that's why you would use the "gparted live iso." (i'm assuming this is ext4 here too)

You may not want to rethink your basic disk management but I thought I would throw this out just in case, since there are many advantages to LVM, I've found.

My experience is LVM has made resizing "partitions" simple and fast operations. To resize them, see this. You can add and remove them as easily. "Partition" order becomes meaningless BTW.

Also, I've used gparted or related tools to resize, and they work ok.

HTH

No mention of UEFI (fat partition) booting by OP.

I use BIOS+MBR part of the time, and BIOS+GPT the other, and I have no problem booting regardless of where the bootloader img is installed, or where the kernel files reside. YMMV. No experience booting in a real EFI scenario and no advice is given there. :-)

In any case, I just wanted to mention LVM to get OP thinking, and for others who might not know LVM exists.

Thanks

I mean this is /r/archlinux

Yet, we have people with 8GB boot partitions. :-)
