Hi, We've several systems running 3.1.5 since it was new, happily without incident. The time has come to upgrade to 3.3.0, so I want to make sure I have the instructions right to minimize downtime. From here: http://gluster.org/community/documentation//index.php/Main_Page I'm sent to here: http://vbellur.wordpress.com/2012/05/31/upgrading-to-glusterfs-3-3/ which has as its most recent comment: Hi, I tried to upgrade from 3.2.1 to 3.3.0. It looked fine at first sight. But I found that adding new 3.3.0 nodes to the upgraded cluster fails. It?s probably because 3.2.1?s volume config lacks ?username/password? authentication entries in ?info? and ??vol?. My workaround is:.... Which has me thinking If this is a problem for 3.2.x, it's probably a problem for 3.1.x. Since the workaround suggested isn't fully specified -- "Modify above files by hand (adding username/password auth entries.)" doesn't lead to a complete picture of what the modifications should look like -- I'd like to ask Is it the general case that this step will be needed? If so, what's the complete description of what to do there? Thanks, Whit
