[SOLVED] Trouble moving to EXT3 for PogoPlug V2

[huntrm]

Am new to Linux, but muddling my way through the OS. Have it successfully installed on my PPlug, have Apache running, have automatic time/date settings working, few other tweaks so I'm beginning to get this stuff!

I'm wishing to move from EXT2 to EXT3.

Am using this guide: https://wiki.archlinux.org/index.php/Co ... t2_to_ext3
Also read this posting: viewtopic.php?f=18&t=2580

Here's my file system:

$this->bbcode_second_pass_code('', '
[root@webserver ~]# df -T
Filesystem Type 1K-blocks Used Available Use% Mounted on
rootfs rootfs 988212 661008 277004 71% /
/dev/root ext2 988212 661008 277004 71% /
devtmpfs devtmpfs 126160 0 126160 0% /dev
run tmpfs 126244 228 126016 1% /run
shm tmpfs 126244 0 126244 0% /dev/shm
tmpfs tmpfs 126244 0 126244 0% /tmp
')

I enter the following command to set up a journal:
$this->bbcode_second_pass_code('', '
[root@webserver ~]# tune2fs -j /dev/root
tune2fs 1.42.5 (29-Jul-2012)
tune2fs: No such file or directory while trying to open /dev/root
Couldn't find valid filesystem superblock.
')

I must be a missing a step, or misunderstanding something to start the process of moving this partition to EXT3? Any ideas?

Finally and a much different question but figured I'd ask it here, I'm using a 1GB USB stick, and would like to use a larger stick (e.g., 10GB). How do I copy from one stick to another?

1. Your filesystem has to unmounted to make a modification like this. Actually you are lucky it doesn't work this way because you need to change a u-boot parameter usb_rootfstype to ext3 before you can boot from ext3. So use your pc and linux live cd/linux installation and add a journal there but before do "fw_setenv usb_rootfstype ext3". Also... it wouldn't be /dev/root, but would be /dev/sdX1 where x is any letter from a to z

Thanks for the help. I got the new usb card formatted on a linux box as root, and ext3 - used gparted under ubuntu to make this happen.

I now have two USBs mounted to this linux PC:
- The pogo USB card (EXT2) is mounted at /dev/sdb1
- The new USB card (EXT3) is mounted at /dev/sdc1

When I try following:
- sudo su
- then cp -ar /dev/sdb1 /dev/sdc1

Nothing happens, it's almost as if the command isn't taking. I appear to be at root, and both USBs are mounted. If I unmount them, then I'm not sure how I can see them.

This is in Ubuntu, where I'm using the console.

EDIT: Just tried FileManager in Ubuntu with copy/paste of the files, and looks like there's a permissions issue with the pogo usb card.

Thanks.

You can't directly access the drives like that. You only unmount them and directly access devices when whey have to be (like formating). Get them mounted and then do the cp.

cp -ar /media/mountpoint1 /meida/mountpoint2

[huntrm]

Thanks for the help, really appreciate it. Am struggling as you know. Here's what's under the media directory:

$this->bbcode_second_pass_code('', '
root@desktop:/media# dir
4046bdca-3095-4547-a9dd-fe4a6f134055 4cfa5462-0b0a-4c28-b3a8-4b76915c729f usbdrive
root@desktop:/media#
')

And when I check mount, here's what's listed. You can see the ext2 and the ext3 usb drives at sdb1 and sdc1:

$this->bbcode_second_pass_code('', '
root@desktop:/media# mount
/dev/sda5 on / type ext4 (rw,errors=remount-ro)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
none on /sys/fs/fuse/connections type fusectl (rw)
none on /sys/kernel/debug type debugfs (rw)
none on /sys/kernel/security type securityfs (rw)
udev on /dev type devtmpfs (rw,mode=0755)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)
tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755)
none on /run/lock type tmpfs (rw,noexec,nosuid,nodev,size=5242880)
none on /run/shm type tmpfs (rw,nosuid,nodev)
/dev/sdb1 on /media/4046bdca-3095-4547-a9dd-fe4a6f134055 type ext2 (rw,nosuid,nodev,uhelper=udisks)
none on /tmp/guest-Jc6pXv type tmpfs (rw,mode=700)
gvfs-fuse-daemon on /home/<username>/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=mcphail)
/dev/sdc1 on /media/4cfa5462-0b0a-4c28-b3a8-4b76915c729f type ext3 (rw,nosuid,nodev,uhelper=udisks)
')

Am I to mount them differently, or umount them, and then locate them, then do the CP? Again, appreciate your help, just having hard time following your last note.

[moonman]

You didn't label them when you formatted them (flash drives).

$this->bbcode_second_pass_code('', 'cp -ar /media/4046bdca-3095-4547-a9dd-fe4a6f134055 /media/4cfa5462-0b0a-4c28-b3a8-4b76915c729f')

Proper command to list folder contents is "ls". I don't know when they started including "dir". Sounds like DOS to me

You could just unmount the ext2 drive with "sudo umount /dev/sdb" and then add journal with "sudo tune2fs -j /dev/sdb1" command

[huntrm]

Sorry for late response. Yeah, I think that "dir" command was me hitting a wall out of frustration... Just typed in whatever I felt like.

I'm happy to say I got this working. It wasn't pretty. I did following:
- Installed Ubuntu on a PC
- Was able to get Ubuntu to journal/update the USB stick to EXT3 - I believe I used Nautilus to do this


Am now on a 32GB USB stick with the pogoplug V2, and I'm happy...

Now, I'm having hell of a time getting Samba with SWAT working so that the directories will properly work in Windows. I'll post that issue somewhere else!

You forget to explain what was the need to move from EXT2 to EXT3 for ArchLinux on a USB Stick? Did you experience any issues? Do you think, adding journaling will extend the stick's service life or speed?

[moonman]

I suppose he's looking for reliability more than anything else.

Just use the guide to setup samba instead of swat. You will save yourself some time
