[Gluster-users] Upgrading from 3.0.4 to 3.0.5

[Joe Warren-Meeks]

I've done just this in our integration environment and our production
environment.

I halted my application on the first server, unmounted the filesystem,
halted glusterfsd, upgraded it, restarted glustersfd and mounted the
filesystem. I checked that read/writes were fine and then brought it
back into service.

I left this for 24 hours, then repeated the process on the secondary
node.

You shouldn't have any problems.

Subject: [Gluster-users] Upgrading from 3.0.4 to 3.0.5

I am planning to upgrade a Gluster installation from 3.0.4 to 3.0.5.  
Can I do so in a piecemeal manner without taking the volume out of 
service?  In other words, can I bring down one replication server, 
upgrade it, and bring it up again while the other servers are running?  
Also, will 3.0.4 clients work with 3.0.5 servers and vice-versa?  If so,

then it sounds like I could slide in the upgrade without major 
disruption of service.

Thanks,
Steve
