### Consistency Guarantees

MinIO follows strict **read-after-write** and **list-after-write** consistency model for all i/o operations both in distributed and standalone modes. This consistency model is only guaranteed if you use disk filesystems such as xfs, zfs or btrfs etc.. for distributed setup.

**In our tests we also found ext4 does not honor POSIX O_DIRECT/Fdatasync semantics, ext4 trades performance for consistency guarantees. Please avoid ext4 in your setup.**

	// fsIDtoInfo is a map from filesystem id to its stats. This will be used
	// as a cache to avoid querying cAdvisor for the filesystem stats with the
	// same filesystem id many times.

// The tests defined here test the compliance of filesystems with the API

// As some filesystems require special setup, these tests are run manually.

// Each filesystem implementation can be provided by DSOs, so we provide the

## Test using MinIO Client `mc`

`mc` provides a modern alternative to UNIX commands like ls, cat, cp, mirror, diff etc. It supports filesystems and Amazon S3 compatible cloud storage services. Follow the MinIO Client [Quickstart Guide](https://min.io/docs/minio/linux/reference/minio-mc.html#quickstart) for further instructions.
