Only 2G on my Arch

[Jzarecta]

I wonder if people can advice me how to extend the memory of my Chromebook HP 14. I am on a 16GB HD but when I put chroagh only shows 2GB. I have a complex partition table which involves up to 12 different partitions.

If anyone is related with this setup can anyone advice me how to add more space. (I could mount/nuke one of these partitions are mount it as home?).

I dont want to touch it since they are label as ChromeOS partitions, but it seems a bit odd they are triplicated. Hopefully some chromebook expert can explain me why all those partitions and their porpouse.

Can you post the output of df and cgpt show /dev/sda?

It appears that you installed Chrubuntu at some point.

The easiest way to recover your partition table is to burn a recovery USB disk, and restore your system (that'll wipe everything, so backup your chroot first).

Alternatively, you could mount ROOT-C//dev/sda7 to a location of your choice and install crouton on that (you'll need to mount the partition on every boot).

Otherwise, you can also restore your partition table what you'd need to do is (I let you figure out the details):

• Backup your existing chroots
• Remove KERN-C and ROOT-C
• Resize STATE so that is spans over the freed up space
• Use resize2fs to resize the STATE partition.

No I didnt, I tried to install Arch directly as dualboot. Which used /dev/sda7 as a root partition.
https://wiki.archlinux.org/index.php/HP_Chromebook_14#Create_Filesystem_and_BIOS_Partition

However due to lack of drivers I decided to use this script to get arch through crouton, however the live partition is a very small 2GB partition, I would like to take out all the rest of the partitions and use my HD to the max. But I am not sure if I would nuke critical partitions for chromeOS.

UPDATE: I have bigger problems trying to move /usr/ to sda7 and basically bricked my Chromebook. I havent been able to restore to machine state even using the recovery image:

I wont be able to go ahead with these steps until I have recovered chromeos effectively, however my original question still is active. I want to know what are those partitions used for and why are they needed by ChromeOS.

Regards.

Oh, ok. The "symptoms" are the same.

Have a look at my last post. KERN-C/ROOT-C are not needed by Chromium OS. The rest is (see http://www.chromium.org/chromium-os/chromiumos-design-docs/disk-format).

Oh, that should really not happen. What exactly have you tried? Are you getting any error message?
