obi458 opened a new issue #732: MacOS and time machine
URL: https://github.com/apache/couchdb/issues/732
 
 
   When time machine runs on the couchdb data folder the compaction failed and couchdb shutdown:
   
   I added couch_log to see why, this gives me the path "/Volumes/Time"!!!!!: 
   
   abs_path(Path0) ->
       couch_log:debug("-------------------- abs_path ~p", [Path0]),
       {ok, Info} = file:read_link_info(Path0),
       case Info#file_info.type of
           symlink ->
               {ok, Path} = file:read_link(Path0),
               abs_path(Path);
           _ ->
               abs_path2(Path0)
       end.
   
   and gives:
