Across a number of different flavors of Linux as well as AIX, I need to
clean up our splunkforwarder space. I've tried numerous different
approaches and am running into errors. This should be rather simple, but it
is proving not to be. Below is my latest iteration and some of the
relevant errors.
My next approach will to be straight up df -h (df -g for aix) with some awk
stuff...also checking if the mount even exists (it doesn't necessarily on
every system). But, I think this should be simpler to do with normal
Ansible modules.
Any ideas on the obvious bits I'm missing?
*Relevant playbook portion:*
tasks:
# - name: Test for 20% disk space available
# assert:
# that:
# - not {{ item.mount == '/opt/splunkforwarder' and (
item.size_available > (item.size_total|float * 0.6) ) }}
# with_items: '{{ ansible_mounts }}'
# ignore_errors: yes
# register: disk_free
- name: Test for 20% disk space available on {{ mountname }}
assert:
that: mount.size_available > mount.size_total|float * 0.2
msg: Disk space has reached the 80% threshold
register: disk_free
- name: For full systems, run splunk clean
command: "/opt/splunkforwarder/bin/splunk clean all -f"
when: disk_free|failed
vars:
mountname: '/opt/splunkforwarder'
mount: "{{ ansible_mounts | selectattr('mount','equalto', mountname) |
first }}"
*Errors:*
FAILED! => {"msg": "The conditional check '{ mount.size_available >
mount.size_total|float * 0.2 }' failed. The error was: template error while
templating string: expected token ':', got '}'. String: {% if {
mount.size_available > mount.size_total|float * 0.2 } %} True {% else %}
False {% endif %}\n\nThe error appears to have been in
'/app/ansible-playbooks/splunk-clean.yml': line 18, column 7, but may\nbe
elsewhere in the file depending on the exact syntax problem.\n\nThe
offending line appears to be:\n\n\n - name: For full systems, run splunk
clean\n ^ here\n"}
FAILED! => {"msg": "The conditional check 'mount.size_available >
mount.size_total|float * 0.2' failed. The error was: error while evaluating
conditional (mount.size_available > mount.size_total|float * 0.2): {{
ansible_mounts | selectattr('mount','equalto', mountname) | first }}: No
first item, sequence was empty."}
