Bug 1398514

Technically speaking all the boolean values irrespective of the case should work for all the volume options that sets/unsets that option:

on/ON
off/OFF
enable/ENABLE
disable/DISABLE
true/TRUE
false/FALSE
0
1

I have come across the scenario where some of the volume option accepts only one combination of the above said values.

For example: cluster.enable-shared-storage accepts only 'enable' or 'disable'. All other values are deemed as illegal.

I feel all the boolean-value-expecting volume options should accept all the boolean value combination, and we can document one pair of boolean values, uniformly all through the guide.

Sas, is there any option that does not accept enable|disable?

If we document enable|disable as the "official" method, is there any boolean option that will not work with that?

Laura,

I am not sure. As I remember there were close to 300 volume options ( 296 exactly ), out of which we need to look for set/unset volume options. 

I also see for some of the volume options, it makes lot of sense to say 'on' or 'off'. For example:
cluster.self-heal-daemon on
performance.read-ahead on

I did a quick search of volume options that has enable/disable combinations, which is very less (5).

cluster.eager-lock                      enable                                  
cluster.enable-shared-storage           disable                                 
cluster.disperse-self-heal-daemon       enable                                  
features.bitrot                         disable                                 
features.barrier                        disable                                 

With the above all options, only 'enable-shared-storage' and 'gluster volume bitrot <vol>' requires 'enable'/'disable'.

Most of the options are ok with 'on'/'off' combination. It would be good, if we could get some thoughts from Developers as they would have more insight in to this.
