    Post upgrading operating system to F11 in interconnected cluster machines

    Hi everyone!

    I am working on a cluster of 30 commodity PCs on which Hadoop is installed to make it High Performance computing cluster (HPC) and my task is to upgrade the operating system which is fodera 8 to Fedora 11. I have checkedout kickstart procedure explained by Fedora.

    but through this you have to insert media (DVD, CD, USB of iso image) or through GRUB in working node machines to start installation by specifying the location of installation files either on nfs, ftp or http server on the network. so ultimately you have to interact with every individual node through graphical user interface or commandline interface to complete the process of installation.

    Is there any way or administation software through which we make the installation possible without going into every individual node through graphical user interface or commandline interface to complete the process of installation.?

    kindly reply as early as possible!

    Thanks,
    Faiza

    Do you have a DHCP server available to you inside the cluster? You can use PXEBOOT to serve the installer out to nodes with a preseeded kickstart file

    Re: upgrading operating system to F11 in interconnected cluster machines

    hi!
    Thanks for the suggestions.
    I have tried DHCP server configuration on the master node in cluster and tried out kickstart+DHCP but DHCP server can tell nodes about the location of iso image file that may be on nfs but still i have to insert media (LiveCD)in the node machine to enter command "linux ks" at boot: so still i have to interact with machines through monitor and keyboard which i really want to avoid because its very difficult to do this thing on 30 pcs individually.

    I haven' t tried PXEBOOT uptill now.

    Is there any way that i remotely ssh to machine and enter command on "boot cmmand line" rather than inserting media(cd, dvd, or usb) to start installation.

    i have PXEBOOT but it installs through vnc. is there any way that we make PXEBOOT installation without vnc?

    See chapter 11 of the Fedora 11 manual.

    Re: upgrading operating system to F11 in interconnected cluster machines

    hi!
    i have a confusion regarding Setting Up An Installation Server.
    Are "pxe boot server", "http server", "dhcp server", "tftp server" configured on same machine or different machines?
    this may be a stupid question but i really don' t know.

    Thanks
    Faiza

    They can be on one box, if you want them to be. Probably easiest if they are.

    Re: upgrading operating system to F11 in interconnected cluster machines

    hi

    i am done with all the steps up till 11.5.1 "Setting up the Network Server". i have skipped steps in 11.4 "Importing the Distribution" because i don' t feel its necessary if we already have an installation distribution (http).

    i am stuck at "11.5.2. PXE Boot Configuration". i have copied pxe installation files "vmlinux and initrd.img" into "/var/lib/tftpboot/"
    I don' t know exactly what does "run the Network Booting Tool on the NFS, FTP, or HTTP server." mean? does it mean that we restart the system and run from network boot after selecting it from boot menu. if this is so then i have already tried it but its not working.
    other than all above i dont have any interface as shown in "11.5.3. Adding PXE Hosts" in my systems menu.

    please tell me what to do next?
