[SOLVED] NTFS Operation Not Supported (45)

Can you summarize what needs to be done?

The NTFS-3G developer is suggesting (here http://tuxera.com/forum/viewtopic.php?p ... 252#p22886) that we try his very latest release "2010.10.2AR.1" which is downloadable here:
http://www.tuxera.com/community/ntfs-3g-advanced/

I would suggest the following steps (a Sparc development environment running RAIDiator 4.1.6 is required for this):
1. Download the source tarball
2. Build using the "--enable-posix-acls" option
3. Post the ".deb" file in this thread so that I can also try it out
4. Install the resulting deb in your ReadyNAS Sparc development/test environment
5. Attach a NTFS formatted USB drive. Then in the root directory of the NTFS drive there must be a directory ".NTFS-3G" and within that directory a file called "UserMapping" (case is important) containing the line

::S-1-5-21-3141592653-589793238-462643383-10000

This tells NTFS-3G to handle ACL permissions. A reboot (or at least an unmount/mount) is required for this to take effect.
6. Create a file somewhere on your main "/c" ext3 partition (/tmp won't work since it isn't mounted with the ACL option)

touch test

7. Add an ACL to this file for any other user (except root) that is defined on your NAS

 setfacl -m u:1234:rw- test

8. Unmount the NTFS drive

umount /USB/USB_HDD_1

9. Remount this time with debug enabled

ntfs-3g -o debug,acl,user_xattr,rw,sync,noatime,allow_other,blksize=4096 /dev/sda1  /USB/USB_HDD_1 2> /tmp/ntfg-3g.err

10. Copy the file with ACLs to the NTFS USB drive

cp -p test /USB/USB_HDD_1/

11. Unmount again (so that we stop getting debug messages in /tmp/ntfs-3g.err)
12. Post here any output/error messages that you see (e.g. Operation not supported) in this thread.
13. Post the contents of /tmp/ntfg-3g.err in this thread

It would also be very useful to repeat steps 5-11 in a ReadyNAS x86 Development environment running the latest released version of RAIDiator so we can see if the problem is limited to just the Sparc Readynas devices or also affects the x86 devices too.

As a very first step you could also run the test once on the Sparc Readynas before upgrading to the latest version of NTFS-3G just to confirm that you see the errors that I am currently seeing.

Thanks,

Mark
