Everything was going so well

JMac

@sdetweil Wow, that was a bit to take in but makes sense (I think).

So if I unmount it how do I get the information off it?
what are the steps here?

sdetweil

@JMac
unmount it
run fsck against it
remount it (hopefully fixed)

then copy your data first thing, DO NOT WRITE TO THE SD CARD

config.js
custom.css
and a list of all the modules in modules (ls *)

if u WANT to try in each module folder do

git remote -v
```⁷
so we know where it came from

quickest way in each module folder

git remote -v | tail -a ~/module_list 

this will list to github source (git remote -v) and append that info  (tail -a) to a known file in your home folder (~ = home)

this is what my backup script does
IF you have any modules that require authentication (run an auth script) 
ls *.json while you are there,

you could also run my backup script, from the web page copy/paste  with -s  pointing to the mounted folder MagicMirror 
https://github.com/sdetweil/MagicMirror-backup-restore

...MM_backup -s /media/??????/MagicMirror some gobbleygoop name (tab key will fill it in after the 1st letter)

this will create the MM_backup folder in your logged on user home folder..  
and do all the work described above (after the mount)

had a little crack at this again, the Mrs is bugging me to get “her” mirror back up and running.

So I’ve run sudo umount /dev/sda1
sudo umount /dev/sda2

Both drive folders from the mounted (old) SD disappeared from the home screen on the pi as expected.

then run, (and got)
sudo e2fsck -f -v /dev/sda2
e2fsck 1.46.2 (28-feb-2021)
rootfs: recovering journal
superblock needs_recovery flag is clear but journal has data.
Run journal anyway ? YES
e2fsck: unable to set superblock flags on rootfs

rootfs: *********** WARNING: filesytem still has errors *********

@JMac bummer

from search
https://unix.stackexchange.com/questions/327863/fsck-wont-fsck-unable-to-set-superblock-flags/386886#386886

was the card readable at all? if so
take it out and put it back in to get mounted
and copy the old config.js, custom.css and do

ls >~/savedlist.txt

in the MagicMirror/modules folder
to some file on your booted card

then we can help you rebuild a new sd card

JMac

@sdetweil hey Sam, I can still see the old list of modules on the old SD card.

If that’s the case can the old card still be used?

the new card is just a completely empty Pi OS, nothing to do with MM on there yet.

Do I need in run the basic install for MM on the new SD to get that running?

sdetweil

@JMac yes, you need to install MM on the new sd.

use my script…
see https://github.com/sdetweil/MagicMirror_scripts
but you should extract your MM config from the sd card.

use my backup script to point to the mounted sd card
see https://github.com/sdetweil/MagicMirror-backup-restore

then install MM
and then restore the config saved to the new sdcard (~/MM_backup folder)

JMac

@sdetweil So install the base of MM on the new SD then follow the steps in your previous post?

I have a feeling it definitely won’t be that easy.

sdetweil

@JMac back is copy/paste from the github, add -s/media/{user}/mountname/MagicMirror

then install MagicMirror
copy/paste from the github link

then restore, copy/paste from the github link. no parms required

JMac

@sdetweil right so when I copy those 2 file’s am I literally just dragging a copy to the new SD’s home screen (just so they’re on the new card) or do they need to go into a MM specific folder on the new card.

I can find both of those files on the old SD but I’m not understanding from

ls >~savedlist.txt.

am I doing that after I’ve installed a fresh MM on the new SD card once that MagicMirror/modules folder exists because running the above command won’t work as the new SD has no reference to MM’s existence.

sdetweil

@JMac copy ?

you go to the web page, and click copy for the command

then to terminal window or ssh window, paste command, hit enter (install and restore, add -s parm on backup)

you are executing the command directly from the web
