In exactly the way one stops any other Linux or Unix program - with
the "kill" command. The manual page will explain how to use it
(obviously, you need to select a signal other than SIGHUP). One uses
"ps" to find the right process ID. When a process is doing disk I/O,
it can't be interrupted within an individual I/O request. However,
most programs split large I/O tasks up into lots of smaller chunks
(perhaps 32KB reads and writes, for example) so this is not very
likely to pose a problem in your case.
