Red Hat Bugzilla – Bug 882278
Last modified: 2013-07-24 13:50:57 EDT
For those who might not know, NUFA is a variant of DHT which places newly created files locally if possible. It used to be quite popular with people who ran "symmetric" configurations (all nodes are both clients and servers) and had apps that wrote lots of scratch files. It still builds and seems to run, but had become deprecated due to the need for special configuration not supported by our CLI. Recently, a few users on the mailing list have specifically asked to have it back, so I did some investigation and it looks like it shouldn't be hard to revive it in a simplified form. Specifically, it can figure out on its own which subvolume is local, so no complex configuration is necessary - just one option to enable it.
CHANGE: http://review.gluster.org/4234 (dht: support auto-NUFA option) merged in master by Anand Avati (email@example.com)
