Swap

Support for managing swap files and devices was added to Kayobe in the Zed release. The custom playbook described below is retained for backwards compatibility but may be removed in a future release.

StackHPC Kayobe configuration provides a swap.yml custom playbook that may be used to configure a swap device.

The following variables may be used to configure the playbook:

swap_group

Host pattern against which to target the playbook. Default is overcloud.

swap_device

Name of the swap device to configure. Default is /dev/rootvg/lv_swap to match the standard host image configuration.

This playbook may be used as a host configure post hook, e.g. for overcloud hosts:

mkdir -p ${KAYOBE_CONFIG_PATH}/hooks/overcloud-host-configure/post.d
cd ${KAYOBE_CONFIG_PATH}/hooks/overcloud-host-configure/post.d
ln -s ../../../ansible/swap.yml 10-swap.yml
