Fedora ARM Secondary Architecture/Standard Operating Procedures

Daily Infrastructure Duties

• Monitor builder status
  • All machines should be ready and enabled.
  • Mount points from Hong Kong - Work Space (builder specific, and /mnt/koji).
• Back-ups - Check all automated back ups
  • Back-ups are located on Ireland, New Zealand - /var/koji-backup/
    • should contain backups of "/etc" and a postgresql dump, run on a daily basis at midnight. These are cronjobs run as root for "/etc" and as koji for the postgresql dump.
    • Ireland should also have a full copy of "/mnt/koji". This is a cronjob run under the root account on Hong Kong.
• Check available disk space on all relevant machines - Hongkong, Ireland and New Zealand.
  • /var and /mnt/koji on Hong Kong

Repo Compose and Release

Repo Closure

• Run 'depcheck' to ensure no broken dependencies that can be resolved.
  • Fix any issues

Compose

• Run 'mash' to create a repository

    mash -o /mnt/koji/mash/beta/f13-arm-2011-05-06 f13-arm

Compose Updates

• Run mash against previously composed repository

    mash f13-updates-arm -o /mnt/koji/mash/updates/13/ -p /mnt/koji/tree/updates/13/ -d /mnt/koji/tree/releases/13/Everything/ -f /mnt/koji/tree/releases/13/Everything/arm/os/repodata/fce31f091be8211a394d8942fcf4f6cbeffa3d40d87b61af55a97b1a88b46987-Fedora-13-comps.xml

Sign Packages

• Temporarily done with 'rpm --addsign'. This is done on Hong Kong using Paul's account. Pass phrase is the old root password. You will need to enter the pass phrase about five times as the packages are signed.

    ls *.rpm | xargs rpm --addsign

• After packages are signed, you must run createrepo again to include the new metadata. Createrepo should be run from the parent directory of "Packages". Please replace the path to groups file accordingly.

   createrepo -g /mnt/koji/mash/beta/f13-arm-2011-05-10/f13-arm/arm/os/comps.xml -d .

• Package signing Standards of Practice Packaging SOP

Create new root filesystem

• On the OpenRD using mkrootfs ( script packaged for rootfs creation, installed on openRD ). You will need to edit the fedora-arm-koji.repo file in /etc/yum.repos.d/ to point to the newly created repo.

    mkrootfs-f13

• edit rootfs adding in correct URL for yum pointing to the latest compose.

    vi etc/yum.repos.d/fedora.repo

• Add in Pandaboard specific hack to "/etc/rc.d/rc.local"

     # horrible hack to respawn serial console
     #while true
     #do
     #/sbin/agetty -L 115200 console vt100
     #done

• Currently the root file system is hosted on Scotland. Copy the root file system using scp.

    scp username@scotland.proximity.on.ca:/var/www/html/fedora-arm/beta/f13/

Release

• Email to ARM mailing list
• Blogpost including links
• Wiki page for the release highlighting changes, notes

Create Koji Builder - Create repo

• Download the ARM patched koji software from Koji Software

yum localinstall koji-1.6.0-2.fc15.arm.noarch.rpm koji-builder-1.6.0-2.fc15.arm.noarch.rpm

• on hongkong create a certificate to be used with the new host. Certificates are created from the directory '/etc/pki/koji' by running the 'certscript'. A link to the certscript

./certscript <hostname>

• copy the cert (hostname.pem) and 'koji_ca_local+fedora.crt' to the new host machines '/etc/kojid/' folder.
• In order for createrepo tasks to work successfully you will need to downgrade the createrepo and yum packages that are included in F16. Download createrepo-0.9.8-5.fc14.noarch.rpm and yum-3.2.29-10.fc15.noarch.rpm

rpm -Uvh --oldpackage createrepo-0.9.8-5.fc14.noarch.rpm
rpm -Uvh --oldpackage yum-3.2.29-10.fc15.noarch.rpm

• Edit the /etc/yum.conf to exclude the above packages from being updated
• edit '/etc/kojid/kojid.conf'. Example of a kojid.config can be found here kojid.conf
• Edit the export file in the nfs server that holds mount koji, at this point which is chile and add the to-be-createrepo machine's info on that file and restart the nfs server
• Add mount koji through nfs in the to-be-createrepo machine (make the mounting directory and edit the fstab) and run mount all

Bandwidth Monitoring - Scotland

• The bandwidth throttling script bwmon is available in /usr/local/bin in scotland
• Activate it by running the following

    bwmon start

• Available commands are start, stop, restart and show
