Red Hat Enterprise Linux CoreOS (RHCOS) must allocate audit record storage capacity to store at least one weeks' worth of audit records, when audit records are not immediately sent to a central audit record storage facility.

An XCCDF Rule

Description

<VulnDiscussion>To ensure RHCOS has a sufficient storage capacity in which to write the audit logs, operating systems need to be able to allocate audit record storage capacity. The task of allocating audit record storage capacity is performed during initial installation of the operating system.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Reinstall the cluster, generating custom ignition configs to allocate audit record storage capacity.

1. Generate manifest files for the cluster by executing the following:

openshift-install create manifests --dir <install_dir>
2. Create a Butane config that configures additional partition by executing the following:

variant: openshift
version: 4.9.0
metadata:
  labels:
    machineconfiguration.openshift.io/role: worker
  name: 98-var-partition
storage:
  disks:
  - device: /dev/<device_name> 
    partitions:
    - label: var
      start_mib: <partition_start_offset> 
      size_mib: <partition_size> 
  filesystems:
    - device: /dev/disk/by-partlabel/var
      path: /var
      format: xfs
      mount_options: [rw, nodev, nosuid, noexec,...] 
      with_mount_unit: true

3. Create a manifest from the Butane config by executing the following:

butane <install_dir>/98-var-partition.bu -o <install_dir>/openshift/98-var-partition.yaml

4. Create the ignition config files by executing the following:

openshift-install create ignition-configs --dir <install_dir>
