USB Install: Arch Linux SQUASHFS error before first reboot
 
I'm trying to install Arch (core-x86_64) via USB drive onto my ASUS Eee PC 1001PX. After exiting the setup where I am supposed to reboot by typing 'reboot' I am given numerous SQUASHFS errors and cannot continue. Any input results in these errors.

I turned off the computer without reboot. '/dev/sda1' does not mount cleanly. But I can log in. I haven't tried to do anything yet (in fear!). Should I be worried?

I formatted the USB drive numerous times in preparation for this install, and have installed other Linux distros onto it previously, installed them with no (apparent) problems.

Are SQUASHFS errors very serious? Is there anything I can check to make sure they won't happen again?

I'm sorry if my information is too vague. I don't know what the exact errors were and don't know how to find out, either.

Hi, welcome to LQ,

squashfs is a compressed filesystem.
How did you format your partitions? which filesystem?

Can you boot with your installation-USB-drive and mount the filesystem of you new system?

I let the Arch install set up my partitions automatically, ext3 filesystem. (Though in fstab, '/boot' was set as ext2--I'm assuming that's normal?)

Sorry, I'm a complet newb, here. How can I mount the filesystem of my new system? Would that mean I have to reinstall everything? Because I've done that a couple times and get the same errors.

If you're able to successfully boot into the new Arch install, I wouldn't be too worried. But do boot up from the USB stick again and run
Code:
fsck /dev/sda1
This should address any problems from not cleanly unmounting your device when you powered off the computer. Does it continue to give errors when you reboot from the installed system?

No, what I mean is to boot a LiveCd or the installation USB-drive, this installer is itself a linux-system. So you will be able to explore your new installed system from "the outside". In order to mount a partition, you'll need an empty directoy, for example /mnt, I'd recommend to create two directories (when the Live-CD/USB) is running
Code:
mkdir /mnt/bootpartition /mnt/rootpartition
mount /dev/sda? /mnt/bootpartition
mount /dev/sda? /mnt/rootpartition
where you please substitute the "?" with the partitionnumbers of the boot- and the rootpartition. Afterwards you can use
Code:
ls /mnt/bootpartition
ls /mnt/rootpartition
in order to check if you have access to the devices.

It says that all four of my 'dev/sdx' mount clean, but the process remains [BUSY] while the others are [DONE]. That's probably nothing, but just in case... (It's also annoying to me because I'm pretty particular.)

When booting the USB drive this time around, I did not get SQUASHFS errors, either. I used the 'shutdown' command successfully. Perhaps I should just leave the '/mnt' directory stuff alone for now.

I appreciate all of your help, markush and reed9.
