How to run RAW I/O's on RHEL / CentOS (Testing Purpose)
For testing storage products or other software's we need to generate some I/O's to test it's functionalities
To run a raw I/O we generally use "dd" command in Linux or Unix system.
# dd if=/dev/zero of=/dev/sdb bs=2048 count=5000
If you want it to keep running in loop;
# while true;do dd if=/dev/zero of=/dev/sdb bs=2048 count=5000;sync;done;
To come out of this loop use "Ctrl + C".
