Let’s list the available disks in the iSCSI server using the below command.
#Install apache spark on centos install#
Install Packages iSCSI Server ~]# dnf install -y targetcli lvm2Ĭluster Nodes dnf install -y iscsi-initiator-utils lvm2 Due to resource constraints, for this demo, we will configure a cluster with iSCSI storage for a demonstration purpose. SAN storage is the widely used shared storage in a production environment. All the nodes in a cluster will have access to the shared storage for the latest data. Shared storage is one of the critical resources in the high availability cluster as it stores the data of a running application.
