Morning,

I am seeing this error and wonder if someone have seen a similar error  
with this module or would know what could be the problem. These are  
the particulars of this problem:

[william@ansible ~]$ rpm -qa | grep ansible  
ansible-2.7.8-1.el7.noarch  
[william@ansible ~]$

Task:

&nbsp;&nbsp;&nbsp;&nbsp;- name: Intialize VDO storage  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;vdo: name={{ansible\_hostname}} state=present  
device=/dev/disk/by-id/scsi-360022190be1e45001dddfc0413294b89-part6  
logicalsize=30T slabsize=32G blockmapcachesize=25G indexmode=sparse  
indexmem=1  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;when:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- ansible\_distribution\_major\_version == "7" or  
ansible\_distribution\_major\_version == "8"  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- "'srv02' in inventory\_hostname"

When I attempt to run the above task, I am getting the error below:

fatal: [srv02.eng.example.com]: FAILED! =\> {  
&nbsp;&nbsp;&nbsp;&nbsp;"changed": false,  
&nbsp;&nbsp;&nbsp;&nbsp;"module\_stderr": "Shared connection to srv02.eng.example.com closed.\r\n",  
&nbsp;&nbsp;&nbsp;&nbsp;"module\_stdout": "Traceback (most recent call last):\r\n File

&nbsp;&nbsp;&nbsp;&nbsp;"msg": "MODULE FAILURE\nSee stdout/stderr for the exact error",  
&nbsp;&nbsp;&nbsp;&nbsp;"rc": 1  
}  
to retry, use: --limit @/etc/ansible/site.retry

What could be tripping this module? I have counter checked that  
modules parameters are correct from documentations, so not sure where  
I am passing string instead of integer.

Regards,  
William
