Reconecting User Data

Troubleshooting
#22

Yes this has been running for a few years.

Fanx a lot

#23

Can you please show:

ls -l /usr/local/bin/node-red
systemctl cat node-red
#24 
root@DietPi:~# ls -l /usr/local/bin/node-red
systemctl cat node-red
ls: cannot access '/usr/local/bin/node-red': No such file or directory
# /etc/systemd/system/node-red.service
[Unit]
Description=Node-RED (DietPi)

[Service]
User=nodered
ExecStart=/mnt/dietpi_userdata/node-red/node_modules/.bin/node-red -u /mnt/dietpi_userdata/node-red

[Install]
WantedBy=multi-user.target
root@DietPi:~#
#25

Okay that looks all good. I checked the dir tree on a fresh Node-RED install an it looks like yours. You could try to conpare the backup files with the live ones, of the missing data is there.

#26

Everything seems to be the same as the backup, but it’s just not being seen.

The last pic is of the InfuxDB’s, when I SHOW them in the terminal they’re not visible

InfluxDB shell version: 1.8.10
> SHOW DATABASES
name: databases

_internal
#27

hmm, I guess the old databases would need to be imported into the new InfluxDB instance. But I’m not sure how this could work. I found something about importing a backup. But this is not what you have I guess

#28

Actually it should have just migrated it when installing with data dir present, at least according to a test I did once :thinking:. But worth to give or a try. Just to be sure, ls -l /var/lib/influxdb is pointing to the DietPi userdata dir, right?

#29

Seems to be correct

Influx and Grafana isn’t too important if it’s lost, and I exported the Node-Red flows separately before which is most important to me, the rest I can rebuild.

So lets call it a day from here, thank you both for all your help

root@DietPi:~# ls -l /var/lib/influxdb
lrwxrwxrwx 1 root root 29 May 17 18:40 /var/lib/influxdb -> /mnt/dietpi_userdata/influxdb
#30

Don’t forget to consider some kind of backup for your system, to avoid similar experience in future. :wink:

Well I did do the normal backup before upgrading which didn’t help much, now I’m going to backup a working image :metal:t3:

#32

best is to store the dietpi-backup on an external USB pen stick or similar. This at least allow you to restore the entire backup on a new installation right during setup.
