Hello Guys,

I have no idea what a “filesystem extension” is, nor how to gather it.  
But once you’ve done that, register it so you can use it in subsequent tasks.

Hi,

Getting below error while using register output in subsequent tasks.

[WARNING]: The value [‘xfs’] (type list) in a string field was converted to u"[‘xfs’]" (type string). If this does not look like what you expect, quote the  
entire value to ensure it does not change.

Instead of have people guess what your playbook might look like based on an error, post it

Here I am posting that playbook. please check it and suggest me…

tasks:

- name: lvm Extend  
shell: “/usr/sbin/lvextend -L +{{ extend\_lv\_size }} /dev/mapper/{{ vg\_name }}-{{ lv\_name }}”

- name: lvm Extend  
shell: “/usr/bin/df -hT | grep {{ Mount\_point }} | cut -d. -f1 | awk ‘{print $2}’”  
register: fs

- name: ‘Extend the FS’  
filesystem:  
fstype: “{{ fs }}”  
dev: “/dev/mapper/{{ vg\_name }}-{{ lv\_name }}”

Suggestion 1: don’t use the same meaningless names for several different tasks. Use something that explains what they do.  
Suggestion 2: use the lvol module instead of shell commands

The variable you set in the register is an Ansible structure, you cant use it directly like you did here:

- name: lvm Extend  
shell: “/usr/bin/df -hT | grep {{ Mount\_point }} | cut -d. -f1 | awk ‘{print $2}’”  
**register: fs**

- name: ‘Extend the FS’  
filesystem:  
**fstype: “{{ fs }}”**  
dev: “/dev/mapper/{{ vg\_name }}-{{ lv\_name }}”  
resizefs: yes

You must check the manual and see its structure. In that case, maybe you want “fs.stdout”.
