[Gluster-users] Node Failure

[Keith Freedman]

Raghavendra,

I didn't chime in cause I wasn't sure this would work, but what I 
always envisioned in a similar situation is the following..  would this work?:

set up a new node as a 2nd AFR node with an empty filesystem under gluster.
run the find/head  command and gluster will realize the local 
filesystem is behind on everything and will AFR the whole tree?

To me, if this would work without risking data loss, this is an ideal 
way to restore a node.

??
Keith
