I/O Scheduler

Ervin

Hi,

I just want to ask if I can change the I/O Scheduler from nood to deadline while the Database is running?

Thanks,

Jim_Knicely

From the docs:

Note: While tests show that changing the scheduler settings while Vertica is running does not cause problems, Vertica recommends shutting down. Before changing the I/O schedule, or making any other changes to the system configuration, consider shutting down any running database.
