Fix MongoDB Issues on Unifi CloudKey Gen 1

Today I had to restart several times my network hardware due to some issues with the cable provider (COX) which they did not want to admit. When it was all finally resolved (by them!) I discovered I could not login anymore on my Cloud Key nor my Gateway Controller.

I could connect to 192.168.1.2 where I was welcomed with the usual 2 buttons to login in either interface but they did not work right. In some occasions I was able to login in the Cloud Key, but it would say that unifi was stopped. In other occasions, I would receive a blank screen trying to login in the Cloud Key panel. I was never able to login in the Controller.

Luckily I could still SSH into the Cloud Key and using the username/password above (ubtn/...) I was given root access.

After much tribulation, perusing /srv/unifi/logs/server.log I noticed some issues with MongoDB that prevented starting the unifi process

My guess is that the many restart corrupted one of the journal files (/usr/lib/unifi/data/db/journal/j._74) and that it was unrecoverable.

To restore things, I simply deleted the file and restarted unifi with

systemctl restart unifi

It took a while (I monitored progress with tail -f /srv/unifi/logs/server.log in another window) but eventually it started it cleanly and I was again able to login both in the Cloud Key and the Gateway Controller.
