BUT. I even found one special case, when LABEL and UUID wasn't converted to DEV.
so, are we ok? (not the cheese).
posting commit now.

(14th Jul, 2013 07:20 AM)Fred Wrote: The size of the USB stick is probably just some sectors smaller than the SD card, but it probably only failed to copy empty space so that's no problem. I think the copy went just fine.
In the cmdline.txt search forand change it to:Code:
root=LABEL=xbian-root-btrfsCode:
root=/dev/sda1
I think I may have it now but how can I tell that it is running from the USB and not still the SD?
I assume that it still needs the SD card inserted for it to boot?
RE: USB Installation - Fred - 18th Jul, 2013 07:18 PM
You can use the command 'df' or 'mount' to see which partitions are mounted.
You will still need the SD card because the RPi will read the bootcode from that.

don't use dd while copying RW mounted partition.
1) you will with no reason copy 16gb is sdcard size is 16gb, even if xbian has not even 500mb
2) dd makes no atomic copy of filesystem's state
3) UUID and LABEL will be the same =>LABEL is possible to change, UUID not so easy
just boot the system, go to terminal and do:
Code:
0) stop xbmc
1) mkfs.btrfs -L xbian-usb /dev/sda1
2) mount /dev/sda1 /mnt
3) rsync -avx —progress / /mnt
4) rsync -avx —progress /home /mnt/home
5) step 3)
6) nano /mnt/etc/fstab :
a) remove line with "/home"
b) change LABEL=xbian-root-btrfs to LABEL=xbian-usb, remove "subvol=root/@," option from "/".
7) edit /boot/cmdline.txt
a) change LABEL the same way as in 6a)
b) change mod_scsi.scan=async to =sync
c) according the need, change number after rootwait=
Quote:The easiest way is:

This only copies the /root partition to your USB drive.
So I am confused. Which one of these methods is the easiest way to copy my root partition to my PNY USB drive????

@Mark
It depends on the Version of Xbian you are running.
Alpha works with the "dd" statement.
Beta works with the "rsysnc" statement.
If you are unsure, from a ssh - type df -T
if it shows something like /dev/mmcblk0p2 btrfs (NOTE btrfs) then run the later "rsysnc" statements.

I am using the beta 1 version.... so I will use the rsync method. Going to try it now......
Ok. So I tried it and on almost every rsync, it says after the file, Operation not permitted (1). Not sure why.. ??

RE: USB Installation - Fred - 19th Jul, 2013 02:59 AM
You have to be root or use sudo before the command
Also remove "subvol=root/@," from cmdline.txt in step 7
RE: USB Installation - Mark - 19th Jul, 2013 03:02 AM
An example of what is shown on almost every line:
rsync: chown "/mnt/usr/include/linux/netfilter_ipv4" failed: Operation not permitted (1)
Still happening. Logged in as Xbian and then did a sudo -s. Typed in password and got into root. Ran the commands and still got the operation is not permitted (1).
RE: USB Installation - Fred - 19th Jul, 2013 03:33 AM
Do you have write access to the mounted drive?
RE: USB Installation - Mark - 19th Jul, 2013 03:40 AM
How do I check that???? Just a note. I reflashed my sd card and I will reconfigure the basics. Then try to rsync to USB again... I will use another USB drive. I plugged the old one in my windows pc and it said it was corrupted. so in a few minutes I will know.

So how do I fix the Operation no permitted 1?
I set my root password and logged in. Everything seemd normal. Then I just ran the cmds as root.
RE: USB Installation - IriDium - 19th Jul, 2013 03:59 AM
Try sudo su instead of sudo -s
RE: USB Installation - Mark - 19th Jul, 2013 04:09 AM
Ok.
I will try that as soon as I can which will be in a few minutes
Thanks for all o the help guys..
But whats the difference between su and just doing it as root? Why wouldnt it work as root? Am I doing someting wrong?
Steps I do:
Format SD CARD using SD CARD FORMATTER
Install XBIAN BETA 1.0
Configure Wi-Fi and Video Calibration
Reboot
Login as XBian
configure root pw
run steps that mk01 gave and seems every time it doesnt work
did I miss a step in there?
Another question:
Must I complete the rsync steps and such (copy root to usb) using SSH or directly in the Xbian CLI?
nope. Still no luck. getting a lot of Operation not permitted (1).
Examples of errors:
rsync: chown "/mnt/etc/network/if-up.d" failed: Operation not permitted (1)
rsync: symlink "/mnt/etc/network/if-up.d/wpasupplicant" -> "../../wpa_supplicant/ifupdown.sh" failed: Operation not permitted (1)
STILL NO IDEA WHY!!?!?!?!?!?
Sorry for the frusteration but after a few days of trying this (this is my thrid day and finally asking for help
)please help!
NO IDEA why it isnt working
A side note:
Could I use the XBIAN installer and install directly to a USB drive??
Then install XBIAN to a SD Card as well? Then edit the cmdline.txt file to point it to the USB?
Will this work?? please helpp!
Ok. Evidently I am doing something wrong and I understand that. I know that mk01 method will work. Maybe because I am a total computer novice, I will need better instructions? Can someone give in-detail (very detail please) of how to do what he said????
Please this would help out much!
RE: USB Installation - Fred - 19th Jul, 2013 06:37 AM
You can´t use the XBian installer for the USB stick.
Can you post the output of the command ´mount´ here.
