From e6bd367b571ad36160dbb149b22e393c4962b44f Mon Sep 17 00:00:00 2001 From: Dave Wysochanski Date: Mon, 28 Jun 2010 20:34:24 +0000 Subject: [PATCH] Implement ignore of mda if bit set by skipping r/w of metadata. We implement ignore of an mda at label_read time by checking for the ignore bit, and then skipping the reading of the vgname and other information in the metadata. This will have an effect similar to a PV found with no mdas. Thus, it will look like an orphan in the cache until we scan the rest of the system and find a PV with metadata, and the mda will not be on the vg->fid->metadata_areas list so no read/writes will be done to the metadata area.
