Same error, it will still look for the sdb…

fatal: [server1]: FAILED! => {“changed”: false, “msg”: “AnsibleError: template error while templating string: unexpected ‘}’, expected ‘)’. String: ARCH={{ ansible_architecture }}\nalias={{ ansible_default_ipv4.alias }}\nDISK1={{ ansible_devices.sda.partitions.sda1.size }}\nDISK2={{ ansible_devices.sdb.partitions.sdb1.size | default(‘Not Defined’ }}\n\n”}

No, different error, because you didn't copy/paste it correctly.
Please read the error first, and try to understand what it means.

fatal: [server1]: FAILED! => {"changed": false, "msg": "AnsibleError: template error while templating string: unexpected
'}', expected ')'. String: ARCH={{ ansible_architecture }}\nalias={{ ansible_default_ipv4.alias }}\nDISK1={{
ansible_devices.sda.partitions.sda1.size }}\nDISK2={{ ansible_devices.sdb.partitions.sdb1.size | default('Not Defined'
}}\n\n"}

No, you did not copy my example correctly.

DISK2={{ ansible_devices.sdb.partitions.sdb1.size | default('Not Defined' }}

The closing ) is missing in your template.

Please remember, some of the server has sdb define, some just sda. I still want my playbook to run, The playbook works well if there is sdb.

TASK [Template] ****************************************************************
fatal: [server1]: FAILED! => {“changed”: false, “msg”: “AnsibleUndefinedVariable: ‘dict object’ has no attribute ‘sdb’”}

I already gave you an example which covered both cases.

############################################################

DISK1={{ ansible_devices.sda.partitions.sda1.size | default('Not Defined') }}
DISK2={{ ansible_devices.sdb.partitions.sdb1.size | default('Not Defined') }}

And is still throwing error...
TASK [Template] ****************************************************************
fatal: [server1]: FAILED! => {"changed": false, "msg": "AnsibleUndefinedVariable: 'dict object' has no attribute 'sdb'"}

It works for me with Ansible 2.9.16 / Jinja 2.9.16 / Python 3.9.1.

Alternatively you can use:

DISK2={% if 'sdb' in ansible_devices %}{{ ansible_devices.sdb.partitions.sdb1.size }}{% else %}Not Defined{% endif %}

THe if else statement work, another arsenal for me. Appreciated it… But

Below is the output:

YEs, the first solution worked when I upgrade my ansible to 2.9, will this work in 2.7? But the new peoblem still persist. i tried it in 2 disks…its not going to new line.

Below is the output:
###########
ARCH=x86_64
alias=ens192
DISK1=1.00 GBDISK2=Not Def
#####################

Was hoping
Disk1
Disk2

Adding an empty line between DISK1 and DISK2 in the template should fix that.
