[Mono.Unix.Native.Errno.ENXIO] -or- The directory UnixFileInfo.Directory cannot be extended because there is no space left on the file system containing the directory. [Mono.Unix.Native.Errno.ENOSPC] -or- There are no free inodes on the file system on which the file is being created. [Mono.Unix.Native.Errno.ENOSPC] -or- An I/O error occurred while making the directory entry or allocating the inode. [Mono.Unix.Native.Errno.EIO]
System.IO.PathTooLongException	UnixFileSystemInfo.FullName was too long. [Mono.Unix.Native.Errno.ENAMETOOLONG]
