dhcpd: no such user: dhcpd

[mircsicz]

I've imported an existing config into a fresh nanosd 16.1.8 CF Install on an ALIX.

And I only had to do so because the system crashed while trying to upgrade with disabled RAM-Disks...

On the first but after restore DHCPD was running and I got an IP, a few hours later dhcpd seems no to be running and when trying to start it I see the following log:

So I ran adduser on the console and could successfully start dhcpd from the webif afterwards...

If your're willing to debug I can supply the config!

This used to happen sparsely, fixed with 16.1.13:

https://github.com/opnsense/changelog/blob/master/doc/16.1.13#L28

To manually fix... Can you first let me know what these commands yield?

# ls -lah /var/db
# ls -lah /root/var/db/pkg

[mircsicz]

Hi Franco,

thx for all your effort! ;-)

That looks ok now, one more to be sure:

# pkg info

It should show all packages...

If that is the case updating to 16.1.14 would likely fix this for you if the dhcpd issue persists on reboot.

[mircsicz]

Hi franco,

as I'm on ALIX I can't upgrade....

and "pkg info" just returns nothing

But it's reproducable, just changed the CF again, and restored the config and the problem was back!

[interfaSys]

This was still happening on 16.1.14, especially after a kernel panic+reboot

[franco]

That means we'll have to start backing up the package database because we really can't trust UFS at all.

[interfaSys]

I just wanted to add that in my case, restarting the box solved the problem, unless this happens at random of course...

[franco]

The first reboot may not recover completely, but the second one does... we've seen this, but don't really know why.

I've added pkg database dump/restore though I do not think it will help very much.

mircsicz, in your case the database is already gone. You can force an upgrade for all packages like this:

# pkg install opnsense

That should bring it back.
