For the benefit of others: >From personal experience (and much communiation with Geoffroy over the months) the following steps appear to be crucial to success in bootstrapping Oscar 6.0.3 on CentOS 5.3:
Before installing anything-oscar: * Ensure that "gpgcheck=0" in /etc/yum.conf * Ensure that "PermitRootLogin=yes" is UNcommented in /etc/ssh/sshd_config * Ensure your /etc/hosts file lists the localhost.localdomain line, your public hostname/IP, and private (cluster/oscar) hostname/IP, are on three separate lines * Ensure your system is updated (yum update) and that you reboot after this to avail of a new kernel and services, if relevant * Ensure that selinux and the firewall is OFF. Behind a campus firewall here, this is moderately safe. It was a requirement for Oscar 5.x and I haven't tested NOT doing this under 6. * Set up the CentOS-x86_64-OSCAR-unstable.repo repo file in /etc/yum.repos.d Cut & paste the contents of http://svn.oscar.openclustergroup.org/trac/oscar/attachment/wiki/repoTesting/CentOS-x86_64-OSCAR-unstable.repo verbatim (deleting line numbers if you need to ;) Next, install the base oscar packages. This also installs yume: yum install oscar * Edit /etc/oscar/oscar.conf and ENSURE the NIC is the one in /etc/hosts you'll be using for the cluster. In my case, I always have to change this to "eth1", at the top of the file, since eth0 is the head node's public NIC. In my case I've assigned eth1 to "192.168.0.100" when setting up my system. Next, setup for the correct distro: oscar-config --setup-distro centos-5-x86_64 This creates /tftpboot/distro and oscar, and does a few others things. I do not find it necessary to copy the contents of a distro DVD/CD into /tftpboot. It IS crucial, however, to ensure you don't become prey to network timeouts during the pool format detection process in the bootstrap. To be sure your NIC assignments are self-consistent, system-sanity The try a bootstrap. If you're very lucky and have a good network connection, it should work. If there are complaints about "Impossible to determine pool format" or some such, things are timing out. Do this: vi `locate PackageSmart.pm` and search for "timeout="; there is only one. Increase its value; in 6.0.3r8521-1 this is "timeout=9", which is better than it used to be (timeout=3"), but I have rarely gotten network bootstrapping to work with values less than 10; Use 15. --- ((((I have also, with some attempts, had to do repeated cycles of "oscar-config --startover"'s followed with manual removal of many packages (with yum), then manual recursive deletion of many directories (results of "find / -name "*oscar*" and also for *OSCAR*) - making sure packman, c3, dhcp*, mysql*, *AppConfig, oda, orm, anything that comes back from "yum list installed | grep oscar", etc, are all removed seems to have been part of this)... followed by reinstalling oscar with yum, etc,before bootstrapping would work. Seems dangerous, and also, oddly, hard to reproduce.)))) No, the most success in bootstrapping I've had (assuming everything else above was seen to thoroughly) was had after making sure the timeout parameter in PackageSmart.pm is set to long enough. I've bootstrapped "straight out of the box" by making sure of this, first.
