Hi Ansible team,
I am using the CSV file as below for nfs volume migration as we have 1000
servers with 100 volumes. Hence, i would like to make to host inventory
using add_host file instead using inventory file. However, the loop is
failing when i use add_host module, if the server has more than one volume .
would anyone please help me on this request as i would like to mount all
the volumes on respective servers as per CSV input?
# cat mounts.csv
host,remote_path,mnt_path,python
host1,nfsflr01:/volahcstg_www_masup_stg_data_01,/myasup/stg/data,/usr/bin/python2.6
host1,nfsflr02:/volahcstg_www_masup_stg_app_01,/myasup/stg/app,/usr/bin/python2.6
host2,nfsflr01:/volahcstg_www_masup_stg_data_01,/myasup/stg/data,/usr/bin/python2.6
host2,nfsflr02:/volahcstg_www_masup_stg_app_01,/myasup/stg/app,/usr/bin/python2.6
# cat mounts.yml
