Hi all,   When I added a dataset in the Manage data libraries, galaxy reported some erros. Anyone knows what's wrong?   Miscellaneous information: Traceback (most recent call last): File "/home/caizexi/usr/galaxy/tools/data_source/upload.py", line 384, in __main__() File "/home/caizexi/usr/galaxy/tools/data_source/upload.py", line 373, in __main__ add_file( dataset, registry, js Job Standard Error Traceback (most recent call last):   File "/home/caizexi/usr/galaxy/tools/data_source/upload.py", line 384, in     __main__()   File "/home/caizexi/usr/galaxy/tools/data_source/upload.py", line 373, in __main__     add_file( dataset, registry, json_file, output_path )   File "/home/caizexi/usr/galaxy/tools/data_source/upload.py", line 270, in add_file     line_count, converted_path = sniff.convert_newlines( dataset.path, in_place=in_place )   File "/home/caizexi/usr/galaxy/lib/galaxy/datatypes/sniff.py", line 99, in convert_newlines     fp.write( "%s\n" % line.rstrip( "\r\n" ) ) IOError: [Errno 28] No space left on device error Database/Build: ?
