Trying to find a linux test tool to write and read IO on a volume
 

As part of my testing, I need to find a tool that will write/read IO to a volume. I need it to fill the volume and then read and verify that the write was successful. Throughput stats would be a plus, but right now, IO verification is a must.

I need the volume to write, read, verify, then repeat until the volume is full.

Can anyone point me to a free tool that can manage this?

thank you.

For IO testing bonnie++ is pretty fair although it doesn't write out to the end of the drive. You can use smartctl to verify the drives integrity if it's supported.
