blockstore
Measures the read/write I/O performance of the underlying disks. It runs five different I/O tests on the disk and reports the Input/Output Operations Per Second (IOPS).
Syntax
blockstore <type>
Parameters
<type> | Type of test: • run-all runs all tests. • r-8k-read-p1 runs random 8K aligned read test with parallelism = 1. • r-8k-read-p256 runs random 8K aligned test with parallelism = 256. • s-256k-read-p16 runs sequential read, 256K aligned, 16 parallel reads. • s-256k-wrt-p16 runs sequential 256K aligned write test with parallelism = 16 with cache pages. • s-8k-wrt-p1 runs sequential 8K aligned write test with parallelism = 1 with cache pages. |
Usage
We recommend that you use the run-all keyword to execute all the tests and display a consolidated report of each test. However, you may run individual tests if you prefer.
After running the blockstore command, enter the service storage restart clean command to start the Edge service.
Example
edge (config) # blockstore run-all
