Thread: Fwd: IO Timeout
I have a question about IO timeouts: We are using the 3ware escalade 9500S series of cards, and we had a drive failure this morning. Apparnetly the card waits 30 seconds for the drive to respond, and if it doesn't, it put's the drive in a fail state. Postgres it seems didn't wait 30 seconds before it decided that the system was upset, and put the database in maintainence mode. Is there a way to increase to IO wait timeout so this doesn't happen?

How do you know that PG is in maintainence mode? I am not sure what PG's maintainence mode is and not aware of any configuration parameters that could control the IO reponse waiting time. Postgres just issues the ordinary file system read/write command and wait for the response.
