kvc-openafs-kmod - README

This is a kmods-via-containers implementation for the openafs-kmod. More information on kmod-via-container refer here

  • OpenAFS specific step:

    1. Copy ThisCell, CellServDB, krb5.conf and cacheinfo for cell inside kvc-openafs-kmod directory. On RHCOS nodes root filesystem is readonly, So afs will be mounted on /var/afs. Also cache dir is in /var/afscache. While starting AFS we mount /var on host in /openafs inside container, e.g. cacheinfo will have below entry

      cacheinfo:

      /openafs/afs:/openafs/afscache:800000

    2. Create a subscription tar as below, inside kvc-openafs-kmod directory.

      tar -czf subs.tar.gz /etc/pki/entitlement/ /etc/rhsm/ /etc/yum.repos.d/redhat.repo

    3. Once above steps are done run ./createmc.sh script. It will create machine config manifest i.e mc.yaml file

    4. Then apply machine config which makes machine config operator in OpenShift to install OpenAFS on all worker nodes.

      oc create -f mc.yaml

    5. In case subscription changes repeat from step 2.
