Enables either udpu (unicast) or udp (multicast) cluster communication (default: udpu)"%>
<% wait_for_all_desc = "\
Enables Wait For All (WFA) feature (default: off).
The general behaviour of votequorum is to switch a cluster \
from inquorate to quorate as soon as possible. For example,\
in an 8 node cluster, where every node has 1 vote, \
expected_votes is set to 8 and quorum is (50% + 1) 5. As soon \
as 5 (or more) nodes are visible to each other, the partition \
of 5 (or more) becomes quorate and can start operating.
When WFA is enabled, the cluster will be quorate for the first time \
only after all nodes have been visible at least once at the same time.
This feature has the advantage of avoiding some startup race \
conditions, with the cost that all nodes need to be up at the \
same time at least once before the cluster can operate.
A common startup race condition based on the above example is that as \
soon as 5 nodes become quorate, with the other 3 still offline, the \
remaining 3 nodes will be fenced.
It is very useful when combined with Last Man Standing.
This option has no effect on CMAN cluster." %>
<% auto_tie_desc = "\
Enables Auto Tie Breaker (ATB) feature (default: off).
The general behaviour of votequorum allows a simultaneous node failure \
up to 50% - 1 node, assuming each node has 1 vote.
When ATB is enabled, the cluster can suffer up to 50% of the nodes \
failing at the same time, in a deterministic fashion. The cluster \
partition, or the set of nodes that are still in contact with the \
node that has the lowest nodeid will remain quorate. The other nodes \
will be inquorate.
This option has no effect on CMAN cluster." %>
<% last_man_desc = "\
Enables Last Man Standing (LMS) feature (default: off).
The general behaviour of votequorum is to set expected_votes and \
quorum at startup (unless modified by the user at runtime, see below) \
and use those values during the whole lifetime of the cluster.
Using for example an 8 node cluster where each node has 1 vote, \
expected_votes is set to 8 and quorum to 5. This condition allows a \
total failure of 3 nodes. If a 4th node fails, the cluster becomes \
inquorate and it will stop providing services.
Enabling LMS allows the cluster to dynamically recalculate \
expected_votes and quorum under specific circumstances. It is essential \
to enable WFA when using LMS in High Availability clusters.
Using the above 8 node cluster example, with LMS enabled the cluster \
can retain quorum and continue operating by losing, in a cascade \
fashion, up to 6 nodes with only 2 remaining active.
This option has no effect on CMAN cluster." %>
