Yes. 'heal-full' should be executed on the node with the highest uuid. Here's how i normally figure out what uuid is the highest: Put all the nodes' uuids in a text file, one per line, sort them and get the last uuid from the list.
To be more precise: On any node, you can get the uuids of the peers through `gluster peer status` output. Gather them all and put them in a file. Next, in order to get the uuid of the node where you executed peer status itself, you use the command `gluster system:: uuid get` Put this uuid as well into the text file. Now execute # cat <text-file-path> | sort The last uuid printed in this list is the one that corresponds to the highest uuid in the cluster.
