@ -311,18 +311,13 @@ NOTE: It is always a good idea to use an uninterruptible power supply
('UPS', also called 'battery backup') to avoid this state. Especially if
you want HA.
On node startup, service 'pve-manager' waits up to 60 seconds to reach
quorum, and then starts all guests. If it fails to get quorum, that
service simply aborts, and you need to start your guest manually once
you have quorum.
On node startup, service 'pve-manager' is started and waits for
quorum. Once quorate, it starts all guests which have the 'onboot'
flag set.
If you start all nodes at the same time (for example when power comes
back), it is likely that you reach quorum within above timeout. But
startup can fail if some nodes starts much faster than others, so you
need to start your guest manually after reaching quorum. You can do
that on the GUI, or on the command line with:
systemctl start pve-manager
When you turn on nodes, or when power comes back after power failure,
it is likely that some nodes boots faster than others. Please keep in
mind that guest startup is delayed until you reach quorum.
