Hi Team

I need to verify if all disk size equal

I have n number of disk. I have written a loop that gives size of disk. Now how do I verify all disks are equal size?

  • name: Check the size of the disk
    shell: |
    bootinfo -s “{{ item }}”
    with_items: “{{ rootvg.stdout_lines }}”
    register: disk_size

Output of bootinfo command is size of disk
$ bootinfo -s hdisk0
70006
$ bootinfo -s hdisk1

70006

Thankyou!

add those numbers to a list, apply the 'unique' filter, then check the length.
If it is 1, then the numbers were all the same.
If it is greater than 2, then there were differences.

I'm a pedant, so I'll suggest that "if it's greater than 1, then there were
differences" :slight_smile:
