NAS and its surprises!
So you have changed your NAS firmware just for fun. Or bought another NAS server, doesn’t matter. You thought it was only plug it in, and all things were there, working like a charm, right? But, you start to notice all sorts of errors, like, services that won’t start, error 500 on your webpages like Nextcloud, like all WordPress of all your clients, like your photos server, etc…
Well, make sure one thing: If you are running NFS shares, look if your new NAS software has the lockd service started.
In my case, I installed ubuntu 20.04 on my NAS. So I just had to run those two lines:
sudo systemctl enable rpc-statd
sudo service rpc-statd start
And my life became colorful again. Hope I helped!
