--- Comment #22 from Sweta Anandpara <sanandpa at redhat.com> ---
Tested and verified this on the build glusterfs-3.7.5-9.el7rhgs.x86_64
The scenarios tested:
Case 1: If read and write counters are set to a non-zero value, setting
features.record-counters to 'off' fails with an error message, as expected.
Case 2: When read and write counters are set to '0', then
features.record-counters is automatically set to 'off', as expected
Case 3: If both the read/write counters are set to '0', setting
features.record-counters to 'on' does *not* pop a note mentioning the same. The
fix mentions that a note should be displayed
Case 4: If any of the read/write counters are set to non-zero value, then
features.record-counters is set to 'on', as expected
Could you please check in, on case 3? It would be good to have a note displayed
on the screen prompting the user to update the read/write counters.
Case 1 logs:
