stress: Spawn 2 workers spinning on write()/unlink() (each worker writes 1G bytes).
$ stress -d ${2} --hdd-bytes ${1GB}
try on your machine
The command "stress -d ${2} --hdd-bytes ${1GB}" is used to generate stress on the specified storage device by consuming a certain amount of disk space.
Here's a breakdown of the individual components of the command:
- "stress" is the name of the command-line tool used for generating stress on a system. It is commonly used for testing purposes or to simulate heavy system load.
- "-d" is a flag that instructs "stress" to perform a specific type of stress, in this case, disk stress.
- "${2}" is a placeholder for the value or variable passed as the second argument to the command. This could be a specific device identifier or path to the storage device targeted for stress testing.
- "--hdd-bytes" is another flag that specifies the amount of disk space to be consumed by the stress test.
- "${1GB}" is a placeholder for the value or variable passed as the first argument to the command. It represents the size of disk space to be consumed, given in gigabytes (GB). This value needs to be specified according to the desired stress level.
Overall, this command will use the "stress" tool to apply stress on a particular storage device by consuming a specified amount of disk space. This might help in assessing the device's performance under heavy disk load conditions.
