From 214dccb317437dab5464456a4eb30c88444370e7 Mon Sep 17 00:00:00 2001 From: Krishnan Parthasarathi Date: Thu, 6 Jun 2013 10:46:57 +0530 Subject: glusterd: Add a cmd for getting uuid of local node Usage: gluster system:: uuid get This is needed since we generate uuid of a node in a lazy manner. ie, we generate a uuid for the node only on the first volume or peer operation, when the node needs an external identity. With this command, we can force[1] the uuid generation, without a volume or peer operation performed. [1]: Querying for uuid (or uuid get), forces uuid to come into existence.
