Open Source, S3 Compatible, Enterprise Hardened and Really, Really Fast
- S3 Compatible : Client(mc), SDK (Java, Javascript, Python, Golang, .Net ..)
high performance, distributed object storage system
Private cloud object storage

Getting Started

MinID 는 Golang으로 제작되어 의존성 없는 단일 파일로 운영 가능
Docker의 경우 Alpine linux 로 배포

MinIO Erasure Code

https://docs.min.io/docs/minio-erasure-code-quickstart-guide.html

Erasure Code

누락되거나 손상된 데이터를 재구성하는 수학적 알고리즘
Erasure code와 Checksums 사용하여 하드웨어 오류 및 자동 데이터 손상으로부터 데이터를 보호
중복 수준이 높으면 전체 드라이브의 최대 절반 (N/2)이 손실 되어도 데이터를 복구 가능
드라이브를 4, 6, 8, 10, 12, 14 또는 16 개의 erasure-coding sets 구성 (최소 4개)

Run MinIO Server with Erasure Code

4 drives setup
Drives를 물리적인 디스크로 구성하면 별도의 Raid 구성이 필요 없음

$ minio server /data1 /data2 /data3 /data4

docker-compose

docker-compose.yml

version: '3'
services:
  minio1:
    image: minio/minio
    command: server /data1 /data2 /data3 /data4 --console-address ":9001"
    container_name: minio1
    environment:
      MINIO_ROOT_USER: minio
      MINIO_ROOT_PASSWORD: miniopass
    restart: always
    ports:
      - "9000:9000"
      - "9001:9001"
    volumes:
      - ./data1:/data1
      - ./data2:/data2
      - ./data3:/data3
      - ./data4:/data4

Distributed MinIO

https://docs.min.io/docs/distributed-minio-quickstart-guide.html
MinIO in distributed mode lets you pool multiple drives (even on different machines) into a single object storage server.
서버를 분리하여 다중 Drives를 지원
- Data protection
- High availability
- Consistency Guarantees

Run distributed MinIO

MINIO_ROOT_USER and MINIO_ROOT_PASSWORD 같은 키로 구성
Erasure Code와 동일한 Drivers 정책으로 분산
Distributed MinIO 와 서버별로 Erasure Code 같이 적용 가능

docker-compose : docker로 4대 서버 시뮬레이션

  minio1:
    image: minio/minio
    command: server http://minio{1...4}:9000/data --console-address ":9001"

$ mc admin policy set myinfo readonly user=cdecl
Policy readonly is set on user `cdecl`

$ mc admin policy set myinfo writeonly user=cdecl
Policy writeonly is set on user `cdecl`

$ mc admin policy set myinfo readwrite user=cdecl
Policy readwrite is set on user `cdecl`

heal - Heal disks, buckets and objects on MinIO server

This command is only applicable for MinIO erasure coded setup (standalone and distributed).
Erasure Code 상태에서 특정 디스크의 데이터가 문제가 있을 경우, 균등하게 데이터를 복구 해줌

$ mc admin heal -r myinfo
 -  data1
