Installing on E02

[moonman]

Invalid journal entries? That's the thing... there is no journal in ext2, it is not a journaling filesystem so it is error prone. ext3 = ext2 + journal

Convert to ext3 then, and change U-Boot parameter "usb_rootfstype" to ext3 before you convert.

$this->bbcode_second_pass_code('', 'pacman -Sy uboot-env
fw_setenv usb_rootfstype 'ext3'')

then shutdown your plug "gracefully"

Plugin your stick/hdd to another linux machine and issue
$this->bbcode_second_pass_code('', 'tune2fs -j /dev/sdX1')

replace X with the appropriate drive letter

Thanks, moonman -- but I don't get it. I followed the instructions in the install explicitly:

6. Now create the ext3 filesystem:
wget http://archlinuxarm.org/os/pogoplug/mke2fs
chmod 755 mke2fs
./mke2fs -j /dev/sda1
mkdir usb
mount /dev/sda1 usb

So shouldn't my file system already be in ext3? The "-j" parameter is to create ext3, right?

The system reads the env variables so it knows what type of fs its booting. If the env sys ext2 ( the default) then it ignores the journal.

Just ran fw_printenv:

usb_rootfstype=ext2

Again, I followed this exactly:

cd /tmp
wget http://jeff.doozan.com/debian/uboot/ins ... ot_mtd0.sh
chmod +x install_uboot_mtd0.sh
./install_uboot_mtd0.sh

Maybe the instructions should be updated to add

fw_setenv usb_rootfstype 'ext3'

?

Thanks for the tip -- I just executed it, then unceremoniously unplugged the Pogo. It came back up fine.

$this->bbcode_second_pass_quote('sjwoo', 'O')kay, I think I figured it out. If I shut down gracefully, then the system is AOK. It's only if I shut down suddenly. When I take out the USB stick and run "e2fsck -f /dev/sdX1" as moonman suggested on my Linux box then put it back in the Pogo, it starts up OK.

This seems like a very serious problem, though. On the subsequent boot, there are invalid journal entries that the system fixes, but am I going to have to do this every time there's a power failure?

I was having same problem with it not loading up.

Moonman gave me this in another thread. I did this before the last section where the first line is cd ..

/usr/sbin/fw_setenv usb_rootfstype 'ext3'

After doing this it reboots without losing it.

I second that, the instructions should include this so everyone is using ext3, especially noobs like me. It would have saved by a lot of time and frustration.

[MI95SHO]

$this->bbcode_second_pass_quote('guiyoforward', '
')Yes! Please update instructions so we get ext3! Lots of traffic to this forum will be avoided

[guiyoforward]

Is this the crucial missing bit?
/usr/sbin/fw_setenv usb_rootfstype 'ext3'
