Hello Bob!

 

I think you will have to do on the active first because if you try to mess with the standby it will complain about a mismatch regarding the float IP and the self ips.

 

My suggestion to you is schedule a window, remove the float, sync, remove all selfs and then re-add everything with the new netmask.

 

I would also advise against editing the config file manually.

 

Best of luck.

 

Cheers, Rafael.
