From 723b6dfba0ee0261002485a1397c5b69a266527c Mon Sep 17 00:00:00 2001 From: Gaurang Tapase Date: Wed, 18 Nov 2015 05:56:39 -0500 Subject: [PATCH] Fix metadata retrieval in GPFS driver GPFS driver was using 'volume_metadata' to get the volume metadata. With versionedobjects, it is to be retrieved using 'metadata' from volume. This patch fixes the issue. It first tries for 'volume_metadata' in the volume object, if not present, it will try for 'metadata' to get the metadata.
