Hi all,
We have a instance about cibadmin recently. A typo of 'cibadmin -r
blahblah' forces the HA into RO mode without any warning, and the
field engineer almost panic. ;)
This leads me to think that cibadmin should give detailed warning
on these dangerous options ahead. But the change will inevitably
change the current behavior of cibadmin.
A draft patch is attached for this purpose. Your insightful
comments are welcome.
Thanks.
