Likewise create users with the job of ‘manager’ on theproxy host and add the users to the group ‘managers’, their password should be set using thepw_mgrvariable.

In the play create a logical volume called Iv0 and make it of size 1500MiB on volume group vgO If there is not enough space in the volume group print a message “Not enough space for logical volume” and then make a 800MiB Iv0 instead. If the volume group still doesn’t exist, create a message “Volume group doesn’t exist” Create an xfs filesystem on all Iv0 logical volumes. Don’t mount the logical volume. Solution as:NO.44 In /home/sandy/ansible/ create a playbook called logvol.yml. In the play create a logical volume called Iv0 and make it of size 1500MiB on volume group vgO If there is not enough space in the volume group print a message “Not enough space for logical volume” and then make a 800MiB Iv0 instead.
