Overview
- The *Ceph testing and development cluster* is a desktop Ceph cluster built using old lab HP Elitedesk mini PC's
- It is located in Peter's cubicle
- The cluster itself is on a private subnetwork behind one of the PC's (the top one in the stack) which functions as a gateway
- The gateway is cephtest.cse.unsw.edu.au (129.94.173.173) and can be reached by SSH from CSE's trust, untrust, and server subnetworks
- The cluster nodes should be added to /etc/hosts on cephtest. The cluster nodes should have no domain component in their names
- The gateway provides access by the cluster nodes to the world using NAT
- The cluster nodes connect to the gateway (cephtest) using a switch filched from the server room (ex: "smartswitch"). The switch has been reset to factory defaults and therefore does not operate in any sort of managed mode
Setting up a PC
- In the HP PC's BIOS reset the security to factory defaults
Installing Debian
- Use the USB boot key on top of the cluster
- Allocate 512M for EFI, 50G for root, and 1G for swap
- Tell installer to set up SSH server ONLY
- Install (and configure) unattended-upgrades, systemd-timesyncd, rsync, man-db, tcpdump lsof, strace
