Sorry to hear that, it sounds like you will need to restore your forum from backup
Here's an interesting one: I have NodeBB set up on localhost mainly to test some minor things. (using Redis, Nginx on Ubuntu 14.04). It's a brand new install I've had running for a couple of days.
I powered off my laptop, went to have dinner and just fired everything up again to find all of my admin settings gone along with all posts, topics and categories I created.
I just run
./nodebb setup again so am back up again (minus all my test data) but any idea why this might have happened?
Well, that's terrifying.
Excuse me while I never reboot my server again.
@Arc had it have been production, I'd have had backups. Being this was my dev site, nothing really lost.
No Redis persistence
It's an in-memory key:value store. If you don't persist it with dumps or AOF or both you'll nuke everything on reboot of redis.
Hope that helps.
@drew Thanks for the heads up! Glad this happened now. I can read up on it and hopefully put something in place.
Now technically, by default, Redis will persist to disk, but any number of reasons might cause it to stop working:
Either way, Redis will output warnings on startup if it cannot write to the
dump.rdb file, so check Redis logs! :)
