Gluster users - Feb 2012 - Replacing a node

I have two servers running gluster 3.1.2 hosting a single replica-2 volume (web
images) on Ubuntu Lucid 64. I need to replace one of the nodes with a new
server. What's the best approach to this? There's not much data, but
I'd like to do it with no downtime if possible.

"gluster volume replace-brick <volume> <old-brick>
<new-brick>"

should do the trick if I remember the syntax correctly.

Have fun,

In this case,when your glusterfs is not busy,you can use command "gluster
volume replace-brick <VOLNAME> <BRICK> <NEW-BRICK>
{start|pause|abort|status|commit} - replace-brick operations",this
operation can replace the old server (brick) automatically. hope this can help
!!
