Ubuntu 18.10 Home Server Problems

[LK LAW]

Every couple of days my Ubuntu home server just stops replying to the services it hosts (piHole, SMB, TimeMachine, SSH, Webmin,...). Though for some reason I can still access the default Apache webpage?

Anyone have an idea on what to do, is this hardware or software related?

 

Yes I’m not on the LTS because I need SMB_fruit in Samba.

You have not given literally ANY useful information, so there is no way of answering this. Go look at your logs first, in all likelihood your issue can be found there.

That's the last output it had before going down that day, though I keep getting this error without the server not responding.

Afaik the sever shouldn't have a swap partition as the os is loaded from an SSD

pick one service. Show us the log for it when it stalls.

im pretty sure ubuntu 18 by default uses a swap file. It's complaining it cant find sdb7. You should look into that. Also you can turn swap off with "sudo swapoff -a", if you have enough ram to run without swap.

A really good fix:
1. Delete Ubuntu Server

2. Get CentOS

 

I had this problem before too, and in short I never found a fix, ran into semi-similar problems on CentOS, but they do not break the server. However this is my experience your mileage may vary a lot.

How hard is it to import the raid array? Main issue I need debian/ubuntu is because of the unifi controller (they only offer support on those 2 distro's).

Ideally I'd love to run freeNas with some Jails/VMs loaded onto them, but the server I have is not powerful enough to do that...
