Adding ClonezillaSE/DRBL to an existing Windows AD environment

Once again, nobody has all the parts and pieces in one location.

  1. Verify that the system has two NIC’s. Issue is DRBL myopia
  2. Install and update Centos 6.x as normal
  3. Install DRBL/Clonezilla per http://winlinuxnet.blogspot.com/2011/07/step-by-step-installing-clonezilla.html
  4. STOP dhcpd IMMEDIATELY!
  5. After drblpush and dcs, do ‘/opt/drbl/sbin/mknic-nbi –check-server-name n‘ to allow any DHCP to pxeboot clients
  6. Create DNS records for DRBL in AD using the LAN port of the DRBL machine
  7. Update DHCP options per step 3
  8. Fix NFS4 as noted at http://lukas.zapletalovi.com/2011/05/export-for-both-nfs-v4-and-v3-clients.html drbl uses hard-coded nfsvers=3 somewhere, don’t bother trying to muck with the template /etc/fstab (dynamically generated?)
  9. Double-check /opt/drbl/sbin/dcs to make sure that the OCS service is running for each node
  10. Disk images go to /home/partimag, that is what you need to slap up to your SAN and share out in Samba.
