Documentation/Wiki

• find a better screenshot for the main page
• go on merging info from the old site
• Complete PDF and online documentation: (section 9.19) Bank holliday and holiday file - (section 10.1 to 1O.2) speak about IPXE - Chapter 10 to check - (section 11.4) Ldap user and authentication - (D3-D4-D5) RCheck database scheme - (E) Complete Computemode boot process with IPXE - Reduce pdf link size - Add participant explanation

explain DHCP/iPXE/DNS and network configuration available from appliances

CM on Debian Squeeze

• Server: update the doc to install CM on top of etch to lenny (or even squeeze since it's nearly release as the new stable)=> Doc for the Debian Squeeze: OK
• OAR 2 installation doc=>Installation of OAR 2.5: OK
• Update node system install doc wrt OAR2=>The same here
• The message to launch the cmaskconfig command should appear after the login=> The script is automatically launch after the login

ComputeMode

PXE smart boot

• test replacement of pxelinux.0 by gpxelinux.0=>We are now using the ipxelinux.0 file
• iPXE=> OK running on computemode 2.0
• provide a http cgi for ipxelinux.0 config file aside the tftp cgi-like file fetching mechanism=> Using IPXE we provide a http script to launch the "deployement"
• Check again the gpxe system => The boot process freeze systematically with virtualbox...

Initrd

• update to 2.6=> Ok the new image is running under Debian Squeeze
  • use udev
  • replace initrd by initramfs=> Ok
• keep an eyes on union fs wrt NFS
  • unionfs/aufs/mini_fo => The Initrd is now mounting an AUFS system
  • http://lwn.net/Articles/355351/
• http://fedoraproject.org/wiki/StatelessLinux/HOWTO -> iscsi
• The dhclient must use the "computemode" option int the dhclient.conf file when requesting the DHCP server=> ok it's working
• Re-implement the available options into the initrd: DDNS, DEBUG, DHCPNOKILL, DHCPREJECT... check with the old initrd from the sarge system
• The initrd must check for several network interface, not only eth0

Computemode Server

• Fixe MRTG configuration to plot graphics (or change the system to use ganglia) =>
• Watchdog is not working there is a failure on NFS: the AUFS system mounted over NFS doesn't allow watchdog to reboot the node anymore: you should mount some "utils" command to be sure that they are available to reboot the node!
• Fixe the /etc/resolv.conf file to search for the computemode domain name =>
• Number of the DHCP option must be increased to be conform with the new RFC!
• The start time for POV demos should begin with the first command launch and not the first results
• RINSE: to build RPM distribution for kameleon debootstrap should be tested
• The size of the computemode server should be increase too
• Check that the wake on lan is working=>OK
• OAR must wake-on-lan nodes when jobs need it for power saving ==> Ok it's working
• OAR must stop nodes 10mn before the end of the computemode service => Ok, admin have to configure the exit command to halt
• Check that we can use a remote nis server to authenticate users
• OAR have to comunicate with an other OAR's from an other cluster

Node system

• provide Debian Lenny / Squeeze instead of Sarge
• update to OAR2
• Define a resource with the OAR cpu/core fields
• Fix the warning during the boot and halt process ==> Ok, we should investigate to fix the last remaining warning about resolconf package and resolv.conf file
• At boot time, if the node has changed its physical configuration (different cpu/core) we have to put the node in the Absent state and to contact the administrators
• We have to check that the CTRL+ALT+DEL command is working even if there is a failure wih NFS => Not working...
• Include the Module software environement manager

Web admin interface

• remove Icatis logo
• add a about page with refs to Icatis, LIG and INRIA, aso
• replace pear/DB which is deprecated (and not packaged in Debian Lenny)
• A new feature: on the scheduling page: it's will be easier to select all the check box of a specific day with just one click on that day => Already implemented
• We have to implement a user management system based on NIS, LDAP...
• The default value for the bootimage into the bootmode page is not the one selected into the database=>Fix with the lastest version
• When the user change the node name with the cmwebadmin interface, the node name have to be changed into the OAR database=>Now working
• Create a new page to visualize the Modules available
• Manage hosts aliases or disable modification for user to change their hhostname
• A participant must only see his own nodes (physical or virtual)
• Implement a scheduler/calendar for the participant to manage their nodes: he can change at any time this calendar. This calendar may only says when a node may reboot in the computemode service => oK
• Only the participant can shows statistics about his nodes
• The main page has to be reorganize

Packaging

• improve cmwebadmin packages
• provide more resources as packages ?

Appliance

• In the virtual box system, when a node has to boot on the local disk, the exit command doesn't work, it's working on physical computer
• Problem with some network drivers, we should contact either virtualbox or IPXE. A solution should be to dynamically load drivers from the dhcp server

HPC integration

• update OAR2 integration

Deployment and new technology

• Study for the integration of general purpose deployment software
  • Opsi (MS Windows deployement)
  • system imager (based on a golden node; can generate dynamically a net boot kernel/initrd)
  • FAI
  • G4U
  • KaDeploy
  • CSM/XCAT (IBM tool which performs redhat kickstart installations; license?)
  • cobbler (bof???)
  • CIT (Cluster Integration Toolkit)
  • DRBL (redhat kickstart or direct images; tools to perform post-installation on windows)
  • unattended (for windows; like RIS but opensource)
  • Norton Ghost
  • Perceus: http://www.perceus.org/
• Some other softwares/technos to follow
  • Cobbler: https://fedorahosted.org/cobbler/
  • Secure PXE boot: http://www.h-online.com/security/news/item/Windows-8-to-include-secure-boot-using-UEFI-2-3-1-1335246.html

Automaton

• Add a Boot-once option
