geo-rep: Fix syncing of hardlink of symlink
Problem: If there is a hardlink to a symlink on master and if the symlink file is deleted on master, geo-rep fails to sync the hardlink. Typical Usecase: It's easily hit with rsnapshot use case where it uses hardlinks. Example Reproducer: Setup geo-replication between master and slave volume and in master mount point, do the following. 1. mkdir /tmp/symlinkbug 2. ln -f -s /does/not/exist /tmp/symlinkbug/a_symlink 3. rsync -a /tmp/symlinkbug ./ 4. cp -al symlinkbug symlinkbug.0 5. ln -f -s /does/not/exist2 /tmp/symlinkbug/a_symlink 6. rsync -a /tmp/symlinkbug ./ 7. cp -al symlinkbug symlinkbug.1 Cause: If the source was not present while syncing hardlink, it was always packing the blob as regular file. Fix: If the source was not present while syncing hardlink, pack the blob based on the mode. > Change-Id: Iaa12d6f99de47b18e0650e7c4eb455f23f8390f2 > BUG: 1432046 > Signed-off-by: Kotresh HR <khiremat@redhat.com> > Reported-by: Christian Lohmaier <lohmaier+rhbz@gmail.com> > Reviewed-on: https://review.gluster.org/18011 > Smoke: Gluster Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Aravinda VK <avishwan@redhat.com> (cherry picked from commit e893962deaabab8e934813f8a0443a8f94e009f2) Change-Id: Iaa12d6f99de47b18e0650e7c4eb455f23f8390f2 BUG: 1486120 Signed-off-by: Kotresh HR <khiremat@redhat.com> Reviewed-on: https://review.gluster.org/18127 Smoke: Gluster Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com>
