Nód LEADER na braisle a fháil

D'fhéadfadh sé a bheith úsáideach nód LEADER na braisle PostgreSQL a bheith ar eolas agat gan dul i gcomhairle leis na logaí. Chuige sin, is leor an t-ordú seo a leanas, arna rith mar root:

patronictl -c /etc/patroni/config.yml topology

Sampla

Ba cheart go mbeadh an fhoirm seo a leanas ar an toradh a fhaightear:

+ Cluster: 15-cleanroomvault5 ------+---------+---------+----+-----------+
| Member           | Host           | Role    | State   | TL | Lag in MB |
+------------------+----------------+---------+---------+----+-----------+
| PSQL_3           | psql_3         | Leader  | running | 2  |           |
| + PSQL_1         | psql_1         | Replica | running | 2  |         0 |
| + PSQL_2         | psql_2         | Replica | stopped | 2  |   unknown |
+------------------+----------------+---------+---------+----+-----------+

Chomh maith leis an LEADER a thabhairt, taispeánann an t-ordú freisin sa cholún deireanach líon na MB moille i gcomparáid leis an LEADER.
Má tá nód díreach stoptha, léireofar an stádas stopped. Tabhair faoi deara, má theipeann ar nód den bhraisle, nach dtaispeánfar an fhaisnéis seo ach go sealadach sula mbaintear an nód den liosta.
