I give up. Back to the old card.
Flatten and re-do the whole card? Or is there some better way to reset it?
No idea.
I utterly give up.
Right, back where I started. Card rewritten, default config done. Just doing an update.
Let’s try again, lol.
I’m not really sure where you got to with this.
There is a password reset file. (yes needs adding to docs). This should work.
php /opt/emoncms/modules/usefulscripts/resetpassword.php
On import, odd it is showing up as sdd - yes the script I think assumes a,b,c
File is at
/opt/emoncms/modules/backup/usb-import.sh
line 49 add sdd to the list
Once imported you need to revert the change in git otherwise it will not pick up any updates later on.
(once imported we can do that)

Ok, no, still no joy. Maybe it is just an unsupported reader?
dmesg output shows it’s now (with the adaptor) on sdb not sdd … so the adaptor “worked” :

Although now I look a bit harder, it seems to be moaning about the incorrect number of partitions! Which, I’m honestly not sure why it would care about! But it is a clue!
I think using the adaptor did move it to sdb, which it feels like should then work…
However it warns about number of partitions.
@TrystanLea - can you help?
This is probably as it is the old partition setup, I thought the import coped with that. Looks like it doesn’t.
So, The route for you now is to put the old card in, reboot and do an ‘export’ to file and then reimport that to the new card.
Sorry

Ah, my problem (I’m pretty sure, anyway) and why I didn’t do that is I do not think I have any export scripts in my pretty bad/broken/I did it wrong, probably old install!
Could I just delete the errant partition? IIRC it’s just swap.
Perhaps I might be missing something, though.
So… On my shiny new EmonSD installation, I have a menu bar at the left side of my browser window, which contains lots of items. Including one called “Backup”.
On my old installation, I have no bar at all there, on the left. I think it’s always been like that, but perhaps when I installed it years ago, I just didn’t realise something was wrong. Might it be that the backup/restore stuff is still physically there, but just the menu referring to it is missing?
I’ll switch back to the old card and do some screenshots.
Oh yes, I’d forgotten that part of the story!
Get the old SD card up and running and we can take it from there.

Hmm sorry about this trouble.
Here’s the point in the usb-import script that tries sda, sdb & sdc - but not sdd.
You could try editing that line in the script to see if it gets any further perhaps? L49
The script is located at /opt/emoncms/modules/backup/usb-import.sh
Beyond that if you get really stuck and your happy to give me remote access I could try and dig into this for you. Dataplicity is relatively easy to install via the command line see: https://www.dataplicity.com, there’s a bit more on it here Remote Access — OpenEnergyMonitor 0.0.1 documentation
Feel free to send me a private message if you’d like to do that.

Hi Trystan, we got past this point, but the USB import then complains there are not enough partitions. I think it must be an old partition layout and the ‘backup’ from the admin didn’t work.

I have now got the old SD card back up and running; came up without a hitch!
Just so you chaps don’t think I’m going mad here’s what I see :
As you can see, it’s weirdly missing loads of stuff! And when I try manually hitting /emoncms/backup/ or similar, it 406s.
Can you post the output from df -h, please?
Use Ctl-E to format, please.

I was mis-remembering. I thought the other partition was swap.
No - it seems it is two partitions
/boot and also /
That does make things a bit trickier I think.

It looks like you have a fairly new version of emoncms on there! But it’s probably is easier to figure out the import using a the new SD card and a usb reader than to figure out the export on the old image… the backup module will be expecting a particular structure for an export which it might not be successful in finding…
