Gluster blog stories provide high-level spotlights on our users all over the world
FIO (Flexible I/O Tester) is a popular I/O benchmark tool. It generates sequential/random read/write/trim synchronously or asynchronously. It supports client/server mode and can spawn multiple worker threads.
FIO supports different IO engines. Previously, FIO runs against Gluster FUSE mount. This doesn’t yield the optimal performance due to the overhead associated with FUSE. But now it merged with the libgfapi engine implementation, so we can generate load directly through libgfapi.
The command line syntax to run a quick test using libgfapi engine is
fio --rw=read --bs=4k --size=1g --runtime=5 --numjobs=1 --group_reporting --ioengine=gfapi --volume=vol --brick=bd-vm --name=/foo.bar
This command reads from Gluster volume vol and brick bd-vm.
