General information
The storage performance test tool allows you to test speed of raw disks or zvols. The tool is available via TUI (Text-based User Interface). To access the tool, perform the following steps:
- While in TUI, press Ctrl+Alt+T.
- Select Add-ons from the menu.
- Select Storage performance test from the list.
You are able to select either a raw device test or zvol device test. Also, you can view test results.Once the test type is selected, you will be asked to select a device to be tested. After performing this operation, a test profile has to be selected. The following types can be chosen:
- ran_write (blocksize 512B)
- ran_read (blocksize 512B)
- seq_write (blocksize 1MB)
- seq_read (blocksize 1MB)
Every random test takes 100 seconds and sequential test takes 150 seconds. Testing progress is shown while running the test. To interrupt the test, press the Ctrl+\ keyboard shortcuts. Test results are available from tool or in logs downloaded from the GUI.
Raw device test
This test allows you to choose disks that are not assigned to zpool.
Zvol device test
This test allows you to choose zvols. To ensure data safety on zvols in zpool, zvol name must contain: data_DESTRUCTIVE_benchmark_test_ONLY. Otherwise, it won’t be listed under the Zvol device selection list. Note that you can overwrite data on this zvol using ran_write or seq_write profile. Once a write profile is selected, you will need to confirm that you understand the risk of using such profiles.
Test results viewer
Here you can view the results or remove them one by one. Test results are also available in logs downloaded from GUI in the “TEST_RESULTS” folder.
