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

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.
