not sure if this helps…
ad_dhcp: if you are using 192.168.1.1 as DHCP, keep DNS service as well, you can have two DNS. You can add pihole ip/hostname to /etc/hosts and luci/networking/hostnames.
ad_static_lease: ensure that ip you picked for pihole is not within the reserved pool on your main dhcp server.
ad_ip_change: check dhcp.lease and dhcp.lease.dynamic files for mac/ip of your pihole, maybe you will find two entries. Some time ago i had two ips assigned and one was from static lease, second from dhcp. I had to go use this tip:
You need to set the interface to "
manual" in the "/etc/network/interfaces" file or else dhcpcd5 cant assign the static IP address configured in "/etc/dhcpcd.conf" to the interface.
ad_lxc: config seems fine. networking part.
ad_hdd_idle: that should not be an issue.
