Usually it is better idea using UUID= or PARTUUID= instead of /dev/sdX in cmdline. As you can see, I have two disks attached to my RPi3, and I never know which one is sda and which one is sdb

Quote:I'll investigate this more when I can. No worries.

I do not doubt it

I have read again the options and am still a little confused.... To make copy on usb (for boot from sd/run from usb) do I need to now add file: at the start of destination - I am guessing not, but want to be sure.

No!

file: makes a complete image of your sd-card (root AND boot partition)
/dev/sdX# copies root partition only to destination partition (that's why you use partition /dev/sdX# instead of device /dev/sdX)

xbian copier does not support copy system to device right now, only to partitions)

10 means copying data of one subvolume fails

Hmmm..... Maybe I am having a bad day, but after successful copy to sda5 I wanted to see if it was all there. So cd /dev/sda5 had nothing and under /media/ there is also nothing showing..... ??? Am I going mad?

Yeah, maybe

cd /dev/sda5 never works, bc you can't cd to a partition, only to a folder

I suppose you have to replug your device before you can cd to /media/... or after copying run a

Code:

sudo mount /dev/sda5 /mnt && cd /mnt && ls -l

[Skywatch]

Yup! - That works.

Now to test again.....

[Skywatch]

Hmmm......Another failure

If this was my first time trying to set this up, I would think I was doing something bad. But this pi and another 2 all worked this way and I am doing nothing strange here. I even tried the root=UUID=(friendly characters here)...way and still it doesn't work.

When it starts up, there is activity on the green led on the pi and for a moment the usb stick lights up to show it is working. But then it all just seems to stop.

I'll have a think about it later on, I need an early night anyway

[Nachteule]

Yeah, tomorrow is another day

Next step: enable initramfs and rescue mode (adding rescue to /boot/cmdline.txt), rebooting Pi and check if /dev/sda5 is mounted correctly

[Skywatch]

OK, so a new day is here

Does this look OK to you?

Terminal

sudo mount /dev/sda5 /mnt && cd /mnt && ls -l
total 0
drwxr-xr-x 1 root root 2 Jan 11 18:05 data
drwxr-xr-x 1 root root 2 Jan 11 18:09 home
drwxr-xr-x 1 root root 2 Jan 11 18:09 modules
drwxr-xr-x 1 root root 2 Jan 11 18:15 root

If so I'll get a monitor and attach to do what you suggested above.

[Nachteule]

Yeah, that's ok

Before you try booting from there, you could run (sda5 has to be mounted on /mnt)

Code:

sudo btrfs scrub start /mnt && sudo watch btrfs scrub status /mnt

to check if all files are ok

[Skywatch]

Looking good so far!

Terminal

xbian@lounge2 ~ $ sudo mount /dev/sda5 /mnt/
mount: /dev/sda5 is already mounted or /mnt busy
/dev/sda5 is already mounted on /media/xbian-copy
/dev/sda5 is already mounted on /mnt
xbian@lounge2 ~ $ sudo btrfs scrub start /mnt && sudo watch btrfs scrub status /mnt

and......then.......

Terminal

scrub status for 7661f9e8-78b1-4040-baeb-74986a6d5ab8
scrub started at Fri Jan 12 15:34:12 2018 and finished after 00:01:14
total bytes scrubbed: 1.76GiB with 0 errors

[Nachteule]

Indeed

Bingo! -- You got it!

But now I get 'fail' message instead!
I have target set to "file: /dev/sda1" as well as the usual "/dev/sda1" and both say error....?

Of course you could also not bugger about with ssh terminal window size in the first place

Cheers!

Added workaround, should never happen again
