# Playbook to prevent virtlogd from running out of files when scaling instances
|
|
# on a compute node.
|
|
#
|
|
# With OS defaults, virtlogd will prevent more than 252 instances per compute
|
|
# due to a maximum number of files it can open.
|
|
#
|
|
# Example:
|
|
#
|
|
# ansible-playbook -i hosts browbeat/scale-virtlogd.yml -e 'max_open_files=10000'
|
|
#
|
