fio (Flexible I/O tester) is the best utility for benchmarking block devices.
Vitastor has a fio driver which can be installed from the package vitastor-fio.
Use the following command as an example to run tests with fio against a Vitastor cluster:
fio -thread -ioengine=libfio_vitastor.so -name=test -bs=4M -direct=1 -iodepth=16 -rw=write -etcd=10.115.0.10:2379/v3 -image=testimg
If you don't want to access your image by name, you can specify pool number, inode number and size
-pool=1 -inode=1 -size=400G) instead of the image name (
