Then you have to build your own Cygwin DLL for testing. > 28 2542465 [main] df 15880 statvfs: (/home/gratz, 0x22A5E0), > file_attributes 48 > 1404 2543869 [main] df 15880 fhandler_disk_file::fstatvfs: 0xC000000D = > NtQueryVolumeInformationFile(\??\H:\GNU, FileFsFullSizeInformation) The call to NtQueryVolumeInformationFile() in fhandler_disk_file::fstatvfs() in fhandler_disk_file.cc (line 737ff), fails with STATUS_INVALID_PARAMETER. This is a NetApp bug, but we may be able to workaround it. Given the lack of complex parameters, and given that, as you claim, this occurs on 32 and 64 bit, I can see only one (well, two) potential culprits, the NtOpenFile calls at lines 751 and 761. One of the following is the problem: - The Netapp drive chokes on the FILE_OPEN_FOR_BACKUP_INTENT open flags. This is *very* unlikely, though, given that it's a required flag to open a directory. Nevertheless, try to set it to 0 just for testing. - Or, Netapp expects the call to run in SYNCHRONIZE mode. To test that, set the open mode to READ_CONTROL|SYNCHRONIZE. This also requires to set the open flags to FILE_OPEN_FOR_BACKUP_INTENT|FILE_SYNCHRONOUS_IO_NONALERT - Or, the READ_CONTROL open mode isn't enough for Netapp. Try to open the file with GENERIC_READ for a start, and then, if that works, try to reduce the flags to something containing READ_CONTROL, FILE_OPEN_DATA, and FILE_OPEN_ATTRIBUTES. Try in combination with SYNCHRONIZE and FILE_SYNCHRONOUS_IO_NONALERT. Corinna -- Corinna Vinschen Please, send mails regarding Cygwin to Cygwin Maintainer cygwin AT cygwin DOT com Red Hat
