 Description   

Hi All,

I would like to understand why the shards servers have a internal cache with config servers list?

I was working in a migration project where I needed to migrate my config servers to replicaset. While I was migrating I had some issues I did a rollback.
After I rollback the config servers and MongoS I started to receive many errors (see bellow) and all errors stopped after I restarted all shard servers.

WA: Error while trying to build custom channels card. Message: database error: mongos specified a different config database string : stored : csReplSet/config01.xx.xxxx.com:27020,config02.xx.xxxx.com:27020,config03.xx.xxxx.com:27020 vs given : config01.xx.xxxx.com:27019,config02.xx.xxxx.com:27019,config03.xx.xxxx.com:27019

Regards,

Thiago Leite

Hi thiagosantosleite@yahoo.com.br,

Thanks for reporting this issue. Unfortunately, downtime is required to downgrade from CSRS to SCCC. As you have observed, restarting all nodes resolved this issue.

Please note that SERVER project is for reporting bugs or feature suggestions for the MongoDB server. For MongoDB-related support discussion please post on the mongodb-users group or Stack Overflow with the mongodb tag. A question like this involving more discussion would be best posted on the mongodb-users group.

Kind regards,
Thomas
