In this CloudLab we deploy a Ceph cluster using openSUSE and DeepSea, a SaltStack formula to deploy Ceph clusters
At the end of Lab 1 we will have a fully functional Ceph cluster, managed by OpenAttic and with all services: Ganesha-NFS, iSCSI gateway, RadosGW, etc
If you are looking for something based on CentOS, check this project
This lab consists of 9 VM based on openSUSE Leap 42.3 with static IP
| Name | IP | Resources | Disc | Services | Description |
|---|---|---|---|---|---|
| ceph-deploy | 192.168.122.11 | 4GB, cores | 1x40G | OpenATTIC, Grafana, salt-master | Deploy and monitoring host |
| ceph-test | 192.168.122.12 | 1GB, 1 core | 1x40G | None | Just a test host to use as a client for iSCSI, NFS, etc |
| ceph-mon{1,2,3} | 192.168.122.2{1,2,3}) | 1GB, 1 core | 1x40G | MON, MGR, MDS, iSCSI Gateway, NFS-Ganesha, RadosGW | Monitors and service gateways |
| ceph-osd{1,2,3,4} | 192.168.122.3{1,2,3,4}) | 1GB, 1 core | 1x40G + 2x30G | OSD | Ceph OSD storage hosts |
NOTE: As you can see, you will need a pretty powerfull computer to run all VM needed by this lab
- Prepare the lab (download needed images)
sudo rake prepare_lab-
Edit the lab.yml file to adapt to your needs (al least add you SSH public key to be able to connect to the lab's VM)
-
If using btrfs, create a "vm" subvolume so you can create snapshot at each Lab stage
sudo btrfs subvolume create vm- Initialize the virtual machines for the lab
sudo rake init_vms- Start/Stop all VM belonging to the lab
sudo rake start_vms
sudo rake stop_vms- Create snapshot at an important milestone (i.e. after installation)
sudo btrfs snap -r vm .snapshots/01_after_installation- Revert to the previous snapshot
sudo btrfs subvol delete vm
sudo btrfs snap .snapshots/01_after_installation vm- Lab 1: Deploy_Ceph
