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

Network settings

Configuration Static
DHCP None
Subnetwork 192.168.155.0/24
