In 12 drive example above, with MinIO server running in the default configuration, you can lose any of the six drives and still reconstruct the data reliably from the remaining drives. MinIO divides the drives you provide into erasure-coding sets of 4 to 16 drives. Minio (www.minio.io), the alternative object storage solution and member of the gang of 4 open source players with Ceph, Swift and OpenIO, has updated its software. Erasure coding is less suitable for primary workloads as it cannot protect against threats to data integrity. MinIO is a high-performance, software defined, S3 compatible object store. I’ve helped Bill by email, and what it happened was he didn’t followed all the steps, meaning, start MinIO with multiple disks, etc. In this lab I am going to use 4 disks for my MinIO server, 100GB each, using of course THIN in VMware, so as not to consume all the space of my VSAN, the VM configuration looks like this: Once we have all the records, we will have to do the next steps for each record, I leave you the steps with the sdb, but you will have to do it with sdc, sdd, and sde: We will have to press n to create a new one, using all the space, and of type 8e, which is LVM to be able to handle it better later in case we want to grow: We will now proceed to create the LVM, with all its settings, as follows: We’ll end up creating a new directory and mounting that new partition: If we want to check that everything went well, with this command we can see everything: Repeat this for each record, you should have something like this: Don’t forget to add them to the fstab, to do this remove the UID with blkid /dev/mapper/vg_xfs_minio_3-xfs_minio_3, in my case for example: We are ready, so let’s move on to the next step. MinIO distributed 4 node 12 disk erasure coding, bitrot protected cluster Print Modified on: Thu, 28 Nov, 2019 at 4:27 PM MinIO distributed mode lets you pool multiple servers and drives into a clustered object store. Erasure code is a mathematical algorithm to reconstruct missing or corrupted data. These classes can be defined using environment variables set before starting MinIO server. Yes, it can, will create another article for it. Example: Start MinIO server in a 8 drives setup, using MinIO Docker image. Benefits of Erasure Coding: Erasure coding provides advanced methods of data protection and disaster recovery. For example, 18 drives are configured as 2 sets of 9 drives, and 24 drives are configured as 2 sets of 12 drives. Distributed MinIO provides protection against multiple node/drive failures and bit rot using erasure code. Deployment In the 12-drive example above, with the MinIO server running at the default settings, you can lose any of the six drives and still reliably rebuild data from the remaining drives. MinIO uses Reed-Solomon code to fragment objects into variable data and parity blocks. More information can be found here – https://docs.min.io/docs/minio-erasure-code-quickstart-guide.html. 3 Minio storage mechanism 3.1 concept understanding. MinIO's erasure coded backend is designed for operational efficiency and takes full advantage of hardware acceleration whenever available. We have everything ready, our particular MinIO, ready, with HTTPS, and using immutable Storage. MinIO supports two storage classes, Reduced Redundancy class and Standard class. MinIO was purpose-built to serve only objects and its single-layer architecture can run in user space and is easily containerized and can be orchestrated using Kubernetes. For example, RAID6 can protect against two drive failure whereas in MinIO erasure code you can lose as many as half of drives and still the data remains safe. Everything about VMware, Veeam, PRTG, Zimbra, etc. MinIO uses Reed-Solomon code to stripe objects into n/2 data and n/2 parity blocks - although these can be configured to any desired redundancy level. Let’s go to the last step, the configuration of Veeam Backup & Replication. And if everything went well, we’ll see what happens next: And of course, by HTTPS, we’ll see the following in the client: Congratulations! While, it can be scaled by just replicating MinIO instances per tenant via an orchestration platform. For RAID, healing can be done only at the volume level which translates into high downtime. For example, in a 12-unit configuration, an object can be split into a variable number of data and parity blocks in all units – from six data and six parity blocks to ten data and two parity blocks. MinIO uses Reed-Solomon code to fragment objects into variable data and parity blocks. Erasure Coding — An analogue to RAID5, RAID6, but with a configurable parity level. Well, well, we’ve come to this part, so let’s not delay any longer, let’s go there, we’ll install the latest version of MinIO using the following command: Once we have everything downloaded and ready, we could launch a simple instance of MinIO, to see what works, without any Erasure Coding, or anything, just for testing, like this: If I access the IP and the port, I see that we can enter a MinIO interface and everything works fine: Once I enter the credentials, I will make sure I have a modern version of MinIO, especially superior to the one recommended by Veeam in their HCL: Okay, since everything works fine for me, let’s take the step and set everything up more securely and elegantly using Let’s Encrypt. The company released recently a new version with single machine, multiple disks erasure coding and bitrot protection. Each object is written to a single erasure-coding set. The question is, does every single object get split into 1024 separate parts?
