The procedures on this page cover deploying MinIO in a Single-Node Single-Drive (SNSD) configuration for early development and evaluation.
|
|
|SNSD| deployments provide no added reliability or availability beyond what the underlying storage volume implements (RAID, LVM, ZFS, etc.).
|
|
|
|
Starting with :minio-release:`RELEASE.2022-06-02T02-11-04Z`, MinIO implements a zero-parity erasure coded backend for single-node single-drive deployments.
|
|
This feature allows access to :ref:`erasure coding dependent features <minio-erasure-coding>` without the requirement of multiple drives.
|
|
|
|
MinIO only starts in |SNSD| mode if the storage volume or path is empty *or* only contain files generated by a previous |SNSD| deployment.
|
|
See the documentation on :ref:`SNSD behavior with pre-existing data <minio-snsd-pre-existing-data>` for more information.

For extended development or production environments in orchestrated environments, use the MinIO Kubernetes Operator to deploy a Tenant on multiple worker nodes.

For extended development or production environments, deploy MinIO in a :ref:`Multi-Node Multi-Drive (Distributed) <minio-mnmd>` topology

:minio-release:`RELEASE.2022-10-29T06-21-33Z` fully removes the `deprecated Gateway/Filesystem <https://blog.min.io/deprecation-of-the-minio-gateway/>`__ backends.
|
|
MinIO returns an error if it starts up and detects existing Filesystem backend files.
|
|
|
|
To migrate from an FS-backend deployment, use :mc:`mc mirror` or :mc:`mc cp` to copy your data over to a new MinIO |SNSD| deployment.
|
|
You should also recreate any necessary users, groups, policies, and bucket configurations on the |SNSD| deployment.

Pre-Existing Data
|
|
-----------------
|
|
|
|
MinIO startup behavior depends on the the contents of the specified storage volume or path.
|
|
The server checks for both MinIO-internal backend data and the structure of existing folders and files.
|
|
The following table lists the possible storage volume states and MinIO behavior:

* - Storage Volume State
|
|
- Behavior
|
|
|
|
* - Empty with **no** files, folders, or MinIO backend data
|
|
|
|
- MinIO starts in |SNSD| mode and creates the zero-parity backend
|
|
|
|
* - Existing |SNSD| zero-parity objects and MinIO backend data
|
|
- MinIO resumes in |SNSD| mode
|
|
|
|
* - Existing filesystem folders, files, but **no** MinIO backend data
|
|
- MinIO returns an error and does not start
|
|
|
|
* - Existing filesystem folders, files, and legacy "FS-mode" backend data
|
|
- MinIO returns an error and does not start

Deploy Single-Node Single-Drive MinIO
|
|
-------------------------------------
|
|
|
|
The following procedure deploys MinIO consisting of a single MinIO server and a single drive or storage volume.
|
|
|
|
.. admonition:: Network File System Volumes Break Consistency Guarantees
|
|
:class: note
|
|
|
|
MinIO's strict **read-after-write** and **list-after-write** consistency
|
|
model requires local disk filesystems (``xfs``, ``ext4``, etc.).
|
|
|
|
MinIO cannot provide consistency guarantees if the underlying storage
|
|
volumes are NFS or a similar network-attached storage volume.
|
|
|
|
For deployments that *require* using network-attached storage, use
|
|
NFSv4 for best results.
