I'm trying to install Arch Linux for a Raspberry Pi 2 according to their instructions on http://archlinuxarm.org/platforms/armv7/broadcom/raspberry-pi-2 on a brand new 64G micro-SD card. I'm doing so using an Oracle VM Virtual Box with Ubuntu v14.04 LTS within a Windows 7 environment. I'm somewhat inexperienced with Ubuntu and Linux in general. Also, SD card and the reader that I'm writing to were VERY cheap from China via ebay, so I'm suspicious of a problem with the SD card at this point.

Anyway, after formatting the disk and creating partitions using fdisk seemingly without incident, I get to step 4 in the Arch instructions, which says to do the following:

mkfs.ext4 /dev/sdX2
mkdir root
mount /dev/sdX2 root

the result I get is:

mount: wrong fs type, bad option, bad superblock on /dev/sdb2, 
missing codepage or helper program, or other error 
In some cases useful info is found in syslog - try 
dmesg | tail or so

dmesg | tail gives the following:

[ 6231.419388]  sdb: sdb1 sdb2
[ 6275.385637] JBD2: no valid journal superblock found
[ 6275.385644] EXT4-fs (sdb2): error loading journal

I found a few other questions with similar problems, such as this, this, and this but none of them have solved my problem.

What is going on?

  • mount typically requires the --types option , also known as -t . Try this mount -t ext4 /dev/sdb2 root. Perhaps partitioning went wrong somewhere. Try reformating the card and starting from scratch. If you don't mind me asking, why would you like to install Arch ? ( Not taking any distro sides here, just offering a possibility of trying other OSs , such as Raspbian or Mate , for considerations ). Arch installations can be tricky and certainly not for newcomers to the linux world Jan 21, 2016 at 4:24
  • I've used arch before. I actually have more arch experience than any other Linux distro. I think it's well suited for embedded applications where I want the most stripped down OS possible.

1 Answer 1


you have problems with your mount command please use this

mount -t ext4 /dev/sdX2 /root

If you have any further questions please do not hesitate to ask me.

  • I actually just found a solution elsewhere. I don't have the exact command I used in front of me anymore, but It supposedly made the ext4 filesystem without journals.

  • @kjgregory may I suggest posting an answer so that future users may find your solution helpful ? Thanks Jan 21, 2016 at 4:59
  • This is the command that got me past the error message: mke2fs -t ext4 -O ^has_journal /dev/sdb2. My Raspberry Pi doesn't seem to boot up yet, so it seems there is still a problem with my setup.
