Hello! I joined the list after this thread: http://comments.gmane.org/gmane.comp.file-systems.btrfs/4589 but I just found it via google, as I''ve hit this same bug with a "real" use-case: the NVIDIA CUDA developer kit. Upon final installation of this package, I hit the ([Error 31] Too many Links) error. It seems that the man pages are all multiply-hard-linked. I''m not sure that I''m reading this right, but here is "ls -l /opt/cuda/man/man3": total 3128 -rw-r--r-- 1 root root 2675 Mar 19 04:06 CUCTX.3.bz2 -rw-r--r-- 1 root root 2202 Mar 19 04:06 CUD3D10.3.bz2 -rw-r--r-- 1 root root 3516 Mar 19 04:07 CUD3D10_DEPRECATED.3.bz2 -rw-r--r-- 1 root root 2153 Mar 19 04:07 CUD3D11.3.bz2 -rw-r--r-- 1 root root 2286 Mar 19 04:07 CUD3D9.3.bz2 -rw-r--r-- 1 root root 3944 Mar 19 04:07 CUD3D9_DEPRECATED.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA64_MEMCPY3D.3.bz2 -rw-r--r-- 1 root root 853 Mar 19 04:07 CUDART.3.bz2 -rw-r--r-- 1 root root 1992 Mar 19 04:07 CUDART_D3D10.3.bz2 -rw-r--r-- 1 root root 3351 Mar 19 04:07 CUDART_D3D10_DEPRECATED.3.bz2 -rw-r--r-- 1 root root 1940 Mar 19 04:07 CUDART_D3D11.3.bz2 -rw-r--r-- 1 root root 2046 Mar 19 04:07 CUDART_D3D9.3.bz2 -rw-r--r-- 1 root root 3671 Mar 19 04:07 CUDART_D3D9_DEPRECATED.3.bz2 -rw-r--r-- 1 root root 3209 Mar 19 04:07 CUDART_DEVICE.3.bz2 -rw-r--r-- 1 root root 1044 Mar 19 04:07 CUDART_ERROR.3.bz2 -rw-r--r-- 1 root root 1673 Mar 19 04:07 CUDART_EVENT.3.bz2 -rw-r--r-- 1 root root 1798 Mar 19 04:07 CUDART_EXECUTION.3.bz2 -rw-r--r-- 1 root root 3255 Mar 19 04:07 CUDART_HIGHLEVEL.3.bz2 -rw-r--r-- 1 root root 2127 Mar 19 04:07 CUDART_INTEROP.3.bz2 -rw-r--r-- 1 root root 7926 Mar 19 04:07 CUDART_MEMORY.3.bz2 -rw-r--r-- 1 root root 2237 Mar 19 04:07 CUDART_OPENGL.3.bz2 -rw-r--r-- 1 root root 1977 Mar 19 04:07 CUDART_OPENGL_DEPRECATED.3.bz2 -rw-r--r-- 1 root root 1008 Mar 19 04:07 CUDART_STREAM.3.bz2 -rw-r--r-- 1 root root 2218 Mar 19 04:07 CUDART_TEXTURE.3.bz2 -rw-r--r-- 1 root root 811 Mar 19 04:07 CUDART_THREAD.3.bz2 -rw-r--r-- 1 root root 2433 Mar 19 04:07 CUDART_TYPES.3.bz2 -rw-r--r-- 1 root root 869 Mar 19 04:07 CUDART_VERSION.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ARRAY3D_2DARRAY.3.bz2 -rw-r--r-- 1 root root 432 Mar 19 04:07 CUDA_ARRAY3D_DESCRIPTOR.3.bz2 -rw-r--r-- 1 root root 401 Mar 19 04:07 CUDA_ARRAY_DESCRIPTOR.3.bz2 -rw-r--r-- 1 root root 493 Mar 19 04:07 CUDA_DRIVER.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_ALREADY_ACQUIRED.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_ALREADY_MAPPED.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_ARRAY_IS_MAPPED.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_CONTEXT_ALREADY_CURRENT.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_DEINITIALIZED.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_FILE_NOT_FOUND.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_INVALID_CONTEXT.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_INVALID_DEVICE.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_INVALID_HANDLE.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_INVALID_IMAGE.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_INVALID_SOURCE.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_INVALID_VALUE.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_LAUNCH_FAILED.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_LAUNCH_INCOMPATIBLE_TEXTURING.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_LAUNCH_OUT_OF_RESOURCES.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_LAUNCH_TIMEOUT.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_MAP_FAILED.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_NOT_FOUND.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_NOT_INITIALIZED.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_NOT_MAPPED.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_NOT_MAPPED_AS_ARRAY.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_NOT_MAPPED_AS_POINTER.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_NOT_READY.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_NO_BINARY_FOR_GPU.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_NO_DEVICE.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_OUT_OF_MEMORY.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_POINTER_IS_64BIT.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_SIZE_IS_64BIT.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_UNKNOWN.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_ERROR_UNMAP_FAILED.3.bz2 -rw-r--r-- 169 root root 69 Mar 19 04:07 CUDA_MEMCPY2D.3.bz2 -rw-r--r-- 1 root root 617 Mar 19 04:07 CUDA_MEMCPY2D_st.3.bz2 . , , and so on. I suppose they did this to "de-duplicate" the man pages. I worked around my installation bug by mounting an ext4 filesystem at /opt/cuda/man so that the installation could complete. # uname -a Linux fun2base 2.6.33-gentoo #1 SMP PREEMPT Wed Mar 17 03:04:23 EDT 2010 x86_64 Intel(R) Core(TM) i7 CPU 860 @ 2.80GHz GenuineIntel GNU/Linux Btrfs Btrfs v0.19 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
