The docs say:

systemctl stop node-red
cd /mnt/dietpi_userdata/node-red
sudo -u nodered npm up --no-audit node-red
systemctl start node-red

So sounds like no data is lost, when updating/reinstalling.
To play it safe I recommend doing a backup beforehand, with dietpi-backup.

But it’s very odd, that it became suddenly unavailable. Sounds like data corruption to me. Maybe a further look into your system would be advisable, to find the cause of this problem.

doing a reinstall at the moment. The last thing I remember doing is trying to install the filesystem node in code red. It failed and I was trying to figure out why. Maybe that node was bad.

Usually a reinstall should be possible by running

dietpi-software reinstall 122
