I have a three member replica set as 1 primary and 2 secondaries A - Primary B - Secondary C - Secondary
Initially I had only one Member A and all CRUD operations were performed on this only.
After some time I had introduced 2 secondories B and C Now again for some reason, secondories were removed and rejoind in cluster.
When I have stepdown node A to make node C primary.
Now it seems to be abnormal:
Node A
rs1:SECONDARY> show dbs TEST 2136.457GB
Node B
rs1:PRIMARY> show dbs TEST 351.329GB
Node C
rs1:SECONDARY> show dbs TEST 2136.457GB
The new primary node is having less data. was it ecame stale at any point of time, if yes, then how should I am able to know it.
Please Help to understand this A
