Part II Deploying Ceph Cluster #
- 4 Introduction and common tasks
Since SUSE Enterprise Storage 7, Ceph services are deployed as containers instead of RPM packages. The deployment process has two basic steps:
- 5 Installing and configuring SUSE Linux Enterprise Server
Install and register SUSE Linux Enterprise Server 15 SP3 on each cluster node. During installation of SUSE Enterprise Storage, access to the update repositories is required, therefore registration is mandatory. Include at least the following modules:
- 6 Deploying Salt
SUSE Enterprise Storage uses Salt and
ceph-saltfor the initial cluster preparation. Salt helps you configure and run commands on multiple cluster nodes simultaneously from one dedicated host called the Salt Master. Before deploying Salt, consider the following important points:- 7 Deploying the bootstrap cluster using
ceph-salt This section guides you through the process of deploying a basic Ceph cluster. Read the following subsections carefully and execute the included commands in the given order.
- 8 Deploying the remaining core services using cephadm
After deploying the basic Ceph cluster, deploy core services to more cluster nodes. To make the cluster data accessible to clients, deploy additional services as well.
- 9 Deployment of additional services
iSCSI is a storage area network (SAN) protocol that allows clients (called initiators) to send SCSI commands to SCSI storage devices (targets) on remote servers. SUSE Enterprise Storage 7.1 includes a facility that opens Ceph storage management to heterogeneous clients, such as Microsoft Windows* an…
