How does the minio cluster determine the size of the erasure set?

[zhaowq32]

NOTE

The impact of Erasure Code Stripe Size and Erasure Code Parity on capacity and fault tolerance can be calculated through the erasure code calculator.The erasure code calculator can choose different Erasure Code Stripe Sizes. Can this value be set in the minio cluster?If not, what is the calculation logic of Erasure Code Stripe Size?Can I get this value through the mc command?

You need to config env MINIO_STORAGE_CLASS_STANDARD before running minio server.
Ex: MINIO_STORAGE_CLASS_STANDARD=EC:2
You can check the default config of minio cluster at here https://github.com/minio/minio/tree/master/docs/erasure/storage-class

K+M = N is the number of disks in cluster.

[zhaowq32]

If the value of K+M is the number of disks in the cluster, then what is the point of modifying the value of Erasure Code Stripe Size in the erasure calculator?https://min.io/product/erasure-code-calculator.In addition, the size of the erasure set is 2-16.

@zhaowq32 Sorry, I just tried one server and many disks. I also don't understand Stripe Size very well.

Still thanks for your reply

[kietheros]

@zhaowq32 Have you found a way to set erasure set size ?

I wasn't asking for official support - I was asking fellow minio users if they knew how to set the K value. ( and you have since told me in the other thread that it is automatic - thanks! )
