By connecting a network card to the first node via mini-PCIe, you can have a 2.5GbE Ethernet port that can perform as a router for the other nodes, says the company. unable to recognize "calico.yaml": Get http://localhost:8080/api?timeout=32s: dial tcp 127.0.0.1:8080: connect: connection refused below is their routing information: @linc978 feel free to join us on slack or create a new github issue. I'm not sure what erasure exactly is, but as far as I understand it's a way for a server with multiple drives to still be online if one or more drives fail (please correct me if I'm wrong). level 2. I’ve been in the technology game since I was about 14 when I made friends with the owner of a local computer shop. We will setup a Thanos Cluster with Minio, Node-Exporter, Grafana on Docker. In contrast, a distributed MinIO setup with m servers and n disks will have your data safe as long as m/2 servers or m*n/2 or more disks are online.

Feel free to join us at https://gitter.im/minio/minio we are happy to help in anyway we can. Did the following on all 4 VMs with SELINUX disabled, same result. Thanks! Successfully merging a pull request may close this issue. The cluster won't start until all nodes are available. With fencing enabled, both nodes will try to fence one another. I moved this discussion to the LFD259 forum since it was created in another class' forum. MinIO Server is a high performance open source S3 compatible object storage system designed for hyper-scale private data infrastructure. Filebeat forwards all logs to Logstash on the manager node, where they are stored in Elasticsearch on the manager node or a search node (if the manager node has been configured to use search nodes). This example removes the node named node4 from the local cluster. As it says localhost:8080 I think there may have been a typo or not copying over the proper ~/.kube/config file when the kubeadm init command was run. We are looking for a self hosted data storage solution similar to S3. For distributed MINIO, each VM ran the same command as follows: rm -rf /root/.minio /mnt/sdc1/.minio.sys, export MINIO_ACCESS_KEY=admin 169.254.0.0/16 dev ens192 scope link metric 1002 There I didn't see these many errors. @pascalandy @linc978 issue context is not related to Docker.

Thanks in advance :). Deploy MinIO on Docker Swarm . MinIO server has two healthcheck related un-authenticated endpoints, a liveness probe to indicate if server is responding, cluster probe to check if server can be taken down for maintenance. MinIO server can be easily deployed in distributed mode on Swarm to create a multi-tenant, highly-available and scalable object store. Are there any plan to support high availability feature like multi copy of storage instance ?
