The setup play in a previously working playbook failed like this

I confirmed with an adhoc ansible setup
ansible staging -m setup

On the server itself this command worked fine
/bin/lsblk -ln --output UUID /dev/xvda1
And there was no obvious issues in syslogs
I then ran this and it worked
ansible staging -m setup -a 'gather_subset=network'
staging | SUCCESS => {
"ansible_facts": {
Then I unmouned and remounted /boot (/dev/xvda1). The subcall then failed
on /dev/xvdc1
A reboot of the machine fixed the issue.
I am curious why the Ansible call to lsblk did not work but the native call
did.
