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.
