From e37ee6d509aa98587d55f9ea73bc831c10761eaa Mon Sep 17 00:00:00 2001 From: karthik-us Date: Fri, 3 Aug 2018 15:55:18 +0530 Subject: posix: Delete the entry if gfid link creation fails Problem: If the gfid link file inside .glusterfs is not present for a file, the operations which are dependent on the gfid will fail, complaining the link file does not exists inside .glusterfs. Fix: If the link file creation fails, fail the entry creation operation and delete the original file.
