Re: [Gluster-devel] Weird lock-ups

When I upgraded I had only one problem... The way to specify a transport type 
in the config file for server and client (I believe?) changed from:
option transport-type tcp/client
to:
option transport-type socket
option address-family inet

See the wiki page here:  
http://www.gluster.org/docs/index.php/Changes_from_1.3_to_1.4

Other than that everything worked great. I tried rolling back to 1.3 at one 
point too and that worked fine, so if you needed to go back it should work...

Ah yes, I remember the inconsistency / splitbrain issue race condition being 
discussed and demonstrated.

Is migration from 1.3.x to 1.4.x transparent? Can I use the same pre-populated 
backing store from 1.3.x, with xattrs set as 1.3.x set them? Or is a 
backup/restore required?

And if there is a problem, is the downgrade path clean (i.e. can I just put 
1.3.x back if 1.4.x goes wrong for me)? Are there any changes to xattrs 
used/set that can cause compatibility problems?

Thanks.

Split-brain issue is known in 1.3.x

The 1.4.x pre-release is in QA mode.
