Gaurav,

I think that it is appropriate to keep the commit force options for replace-brick, just to prevent less experienced admins from self-inflicted data loss scenarios.

The add-brick/remove-brick pair of operations is not an intuitive choice for admins who are trying to solve a problem with a specific brick. In this situation, admins are generally thinking 'how can I move the data from this brick to another one', and an admin that is casually surfing documentation might infer that the replace-brick operation is the correct one, rather than a sequence of commands that are somehow magically related.

I believe that keeping the mandatory commit force options for replace-brick will help give these admins reason to pause and re-consider if this is the right command for them to do, and prevent cases where new gluster admins start shouting 'gluster lost my data'.

Regards,
  Kelvin

Hi all,

Since GlusterFs version 3.6.0  "gluster volume replace-brick <VOLNAME> <SOURCE-BRICK> <NEW-BRICK> {start 
[force]|pause|abort|status|commit }" command have deprecated. Only "gluster volume replace-brick <VOLNAME> 
<SOURCE-BRICK> <NEW-BRICK> commit force" command supported.

for bug https://bugzilla.redhat.com/show_bug.cgi?id=1094119 , Patch http://review.gluster.org/#/c/10101/   
is removing cli/glusterd code for  "gluster volume replace-brick <VOLNAME> <BRICK> 
<NEW-BRICK> {start [force]|pause|abort|status|commit }" command. so only we have commit force 
option supported for replace-brick command.

Should we have new command "gluster volume replace-brick <VOLNAME> <SOURCE-BRICK> <NEW-BRICK>" instead of 
having "gluster volume replace-brick <VOLNAME> <SOURCE-BRICK> <NEW-BRICK> commit force" command.


Thanks & Regards
Gaurav Garg
