Thanks Serge, I have changed the resource agents as you have suggested and
everything appears to be working fine ... example below from a 'crm
configure show'. Still looking for advice on the other items .... anyone ?
primitive PGSQL_DEPOT ocf:heartbeat:pgsql \
params pgdata="/DB_DEPOT/depot/dbdata/data/" pgport="5433"
pgdba="depot" \
op start interval="0" timeout="120" \
op stop interval="0" timeout="120"
