### 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.**

ConfigMap rendering [issue](https://github.com/kubernetes/kubernetes/issues/112081) was found in the 1.25.0 release. When ConfigMaps get updated within the API, they do not get rendered to the resulting pod's filesystem by the Kubelet. The feature has been [reverted to alpha](https://github.com/kubernetes/kubernetes/pull/112078) in the 1.25.1 release.

## Urgent Upgrade Notes

### (No, really, you MUST read this before you upgrade)

## 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://docs.min.io/community/minio-object-store/reference/minio-mc.html#quickstart) for further instructions.

## Upgrading MinIO

has now graduated to Beta.
This allows the kubelet to dynamically retrieve credentials for a container image registry
using exec plugins, rather than storing credentials on the node's filesystem.

### Contextual Logging in Alpha

Kubernetes 1.24 has introduced [contextual logging](https://github.com/kubernetes/enhancements/issues/3077)

- XFS-filesystems are now force-formatted (option `-f`) in order to avoid problems being formatted due to detection of magic super-blocks. This aligns with the behaviour of formatting of ext3/4 filesystems. ([#104923](https://github.com/kubernetes/kubernetes/pull/104923), [@davidkarlsen](https://github.com/davidkarlsen))

- Disable reading of disk geometry before calling expansion for ext and xfs filesystems ([#131636](https://github.com/kubernetes/kubernetes/pull/131636), [@gnufied](https://github.com/gnufied)) [SIG Storage]
