You can bump the 'token' to a higher value (for example 10s ) and adjust the consensus based on that value.

I manage an active/passive PostgreSQL cluster using DRBD, LVM, Pacemaker and Corosync on a Debian GNU/Linux operating system.</div>

Everything is OK, but my platform seems to be quite "sensitive" to small network timeouts which are generating a cluster migration start from active to passive node; generally, the process doesn't go through to the end: as soon as the connection is back again,
the migration is cancelled and the database restarts!</div>

That should be OK but on the application side, some database connections (on a Java WildFly server) can become "invalid"! So I would like to avoid these migrations when this kind of small timeout occurs...<br>

So my question is: which cluster settings can I change to increase the timeout before starting a cluster migration?</div>
