From 8b45b798a1fec498cdad36c79c5976b607bb1be9 Mon Sep 17 00:00:00 2001 From: Amar Tumballi Date: Tue, 4 Feb 2020 23:02:51 +0530 Subject: volgen: make thin-arbiter name unique in 'pending-xattr' option Thin-arbiter module makes use of 'pending-xattr' name for the translator as the filename which gets created in thin-arbiter node. By making this unique, we can host single thin-arbiter node for multiple clusters.
