Issues

APC UPS not killing power

I think this is a Fedora / systemd problem. apcupsd will detect the AC power failure and initiate a shutdown (shutdown -h -H now via apccontrol). But apccontrol killpower does not seem to be called. Also, during shutdown, systemd reports “A stop job is running for APC UPS Power Control Daemon for Linux”. Not sure if this is because the apcupsd service was what kicked off the shutdown command, so it wasn't able to be stopped.

Installation

  • Install base F26 server.
  • dnf update
  • dnf install \
  vim \
  qemu-system-x86 \
  qemu-kvm \
  apcupsd \
  nfs-utils \
  libvirt-daemon-qemu \
  libvirt-client
  • Edit /etc/default/grub:
    • Remove rhgb
    • Decrease timeout
  • grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
  • Add /etc/sysconfig/network-scripts/ifcfg-br0: 
    DEVICE=br0
TYPE=Bridge
DELAY=0
NM_CONTROLLED=no
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.16.20
NETMASK=255.255.255.0
GATEWAY=192.168.16.1
  • In /etc/sysconfig/network-scripts/ifcfg-enp7s0, change BOOTPROTO to none, and add BRIDGE=br0 and NM_CONTROLLED=no
  • chkconfig network on
  • edit /etc/apcupsd/apcupsd.conf and /etc/apcupsd/apccontrol
  • systemctl enable apcupsd.service
  • systemctl enable nfs-server.service
  • firewall-cmd –add-service=nfs
  • Do fixes in https://bugzilla.redhat.com/show_bug.cgi?id=1472062 (disable SELinux and reduce stop timeout of apcupsd service to 10s) to allow apcupsd to work properly
