Hello,

I have tried to run this task on RHEL 8 system and it doesn’t go well. The same task runs fine on RHEL 7.

It does looks like this is a bug to me, anyone made a similar observation or can replicate it with ease?

- name: Set up xfs filesystem on partation for VDO  
filesystem: fstype=xfs dev=/dev/mapper/{{ansible\_hostname}} opts=-K
