stress san storage


Hi,
I'm completely new to linux, I'm using RedHat for the first time.
I have installed it and mounted a SAN disk and created a ext3 file system. I can copy files there, all seems to work.

But I want to generate infinite IO load to the SAN storage, which means, I want to stress it for testing. It's not a maximum IO test, it should just generate load with small block size, that's all.

Any idea how I could do that using native commands? Found some tools, but I'm only able to access the system remotely with ssh and was not able to install them.

Thanks to all in advance!

Hi,

dd command is usefull for such tests. Try
Code:
dd if=/dev/random of=MY_SAN_MOUNTPOINT/somefile bs=4096 count=1000
.
This will create a 4MB file on your SAN mountpoint. Run it in a loop loop to create more such files, edit bs(blocksize) and count to create files as you need.
