The drive for holding my Mongo data is running out of space (data directory: D:\mongo\data). So I decided to move the data directory to another drive that has a larger space (intended directory: F:\mongodata\data).
I learned that I could just copy D:\mongo\data to F:\mongodata\data and modify the dbPath in mongod.cfg to dbPath: F:\mongodata\data (the log is still path: D:\mongo\log\mongod.log). However when I try to connect to MongoDB via MongoDB Compass Community, I get the following error,
connect ECONNREFUSED 127.0.0.1:27017
The command line returns this error,
C:\Users\liding>mongo
MongoDB shell version v4.4.0
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed: SocketException: Error connecting to 127.0.0.1:27017 :: caused by :: No connection could be made because the target machine actively refused it. :
connect@src/mongo/shell/mongo.js:362:17
@(connect):2:6
exception: connect failed
exiting with code 1
I don't know if it is the problem with Windows service since I installed Windows service right after installing MongoDB on my PC. So I followed this by modifying the regedit and restarted my computer. The problem was still there.
I also tried mongod --dbpath "F:\mongodata\data" in cmd following this. It appeared to be working.
