20220226-Clarification regarding delay time of PostgeSQL starting up

Hi to all,       

We are using PostgreSQL 12.3, it is running on the Windows Server.

Database data directory is configured in the network shared path. Unexpectedly it was disconnected and up again.

PgAgent is not connected, when I check the Log, it showing

FATAL:  the database system is starting up

FATAL:  the database system is starting up

……………………………

Other than that, there is no other errors available. For nearly 7 hours database is not connected, after that it’s getting connected. Why it is taking too long time to up. Totally our database has 3.5 TB of data.

Suggest me, how to start the server quickly.

Thanks,

Karthick Ramu
