* DISABLE WATCHDOG! Server will reboot due to watchdog during reboot in filesystem tasks.. BAD!
* Added "TimeoutSec=900" in [Service]-Section '''/etc/systemd/system/lvm2-lvmetad.service''' , otherwise shutdown takes too long time and lvmetad gets killed instead of clean shutdown, Results in failed lv which needs lvchange -ay [lvm] or worse - lvconvert --repair.
* <del> Docker '''/etc/docker/daemon.json''' added "iptables": false.</del> Update: Use /etc/sysctl.d/30-ipforward.conf and /etc/udev/rules.d/99-bridge.rules instead. Docker kills kvm bridges without it.

* DISABLE WATCHDOG! Server will reboot due to watchdog during reboot in filesystem tasks.. BAD!
* Added "TimeoutSec=900" in [Service]-Section '''/etc/systemd/system/lvm2-lvmetad.service''' , otherwise shutdown takes too long time and lvmetad gets killed instead of clean shutdown, Results in failed lv which needs lvchange -ay [lvm] or worse - lvconvert --repair.

* DISABLE WATCHDOG! Server will reboot due to watchdog during reboot in filesystem tasks.. BAD!
* Added "TimeoutSec=900" in [Service]-Section '''/etc/systemd/system/lvm2-lvmetad.service''' , otherwise shutdown takes too long time and lvmetad gets killed instead of clean shutdown, Results in failed lv which needs lvchange -ay [lvm] or worse - lvconvert --repair.
* <del> Docker '''/etc/docker/daemon.json''' added "iptables": false.</del> Update: Use /etc/sysctl.d/30-ipforward.conf and /etc/udev/rules.d/99-bridge.rules instead. Docker kills kvm bridges without it.
