This commit only improves logging whenever ENOSPC (No space on disk) or EDQUOT (Quota limit exceeded) is returned by glusterfs Also, added methods to: - get filename from file descriptor - log with rate limit Caveat: Although raising DiskFileNoSpace results in object-server returning HTTPInsufficientStorage[507] correctly, the swift proxy-server invokes "best_response" method that returns [503] to the user. When write-behind translator is turned on in glusterfs, it may set errno to EIO instead of ENOSPC/EDQUOT. This is documented in BZ 986812 BUG: 985862, 985253, 1020724 Change-Id: Ib0c5e41c11a8cdccc2077f71c31d8a23229452bb Signed-off-by: Prashanth Pai <ppai@redhat.com> Reviewed-on: http://review.gluster.org/6199 Reviewed-by: Luis Pabon <lpabon@redhat.com> Tested-by: Luis Pabon <lpabon@redhat.com> Reviewed-on: http://review.gluster.org/6269
