ES(erasure-coding sets)<br>= Erasure Code Stripe Size
4 to 16 drives per set. (单节点多磁盘也可以启用纠删码)
Each object is written to a single EC set
Minio uses the largest possible EC set size
18 drives: 9 * 2
24 drives: 12 * 2
The drives should all be of approximately the same size.<br>
Erasure Code Parity (EC:N)
N 最大取 ES中磁盘数的一半 (即 最小利用率为 50%)
Nodes
Each node shoud have the same number of drives
NTP: 节点间时间差应小于 15min
N nodes & M drives/node
minio server http://host{1...n}/export{1...m}<br>
Cluster Expanding
minio server http://host{1...n}/export{1...m} http://host{o...z}/export{1...m}<br>
pool 1: host{1...n}
pool 2: host{o...z}
New object upload requests automatically start using the least used cluster.
Each pool should have the same erasure coding parity configuration
drives
Direct-Attached Storage (DAS) with XFS for best performance.
