DHCP services stopped working

MAAS 2.9.2 (snap). Was working ok until memory and disk got exhausted. I fixed those problems but after rebooting the DHCP services are not starting.

~$ sudo maas status
bind9                            RUNNING   pid 1138, uptime 0:11:56
dhcpd                            STOPPED   Not started

syslog                           RUNNING   pid 1258, uptime 0:11:52

Any suggestions please?

Hi @routergod, do you happen to see anything erroneous in /var/snap/maas/common/log/maas.log relating to dhcp? Or perhaps in /var/snap/maas/common/log/rackd.log?

Thanks @cgrabowski. Not got my head around snaps yet, now I know where the logs are :slight_smile:

There is nothing in either maas.log or rackd.log, but regiond.log has this message;

2021-06-09 08:58:43 maasserver.rack_controller: [critical] Failed configuring DHCP on rack controller 'id:1'.

Some kind of config corruption perhaps due to memory and disk issues I had? Its a lab setup, I can rebuild it but wonder if there is a way to recover from here?
