Hi,

I have mounted a NTFS USB using ntfs-3g on a linux system.
When copying a file from one usb to another usb I need to preserve all the timestamps of the file.
For this I need to set the creation time of the file on the target usb to be the same as that on the source.
I was looking at the libntfs-3g source code and I found that I could obtain a ntfs inode using something like this --

ntfs_volume *vol = ntfs_mount(device, MS_READONLY);
ntfs_inode *ni = (ntfs_inode *)ntfs_pathname_to_inode((ntfs_volume *)vol, (ntfs_inode *)NULL, (const char *)file);
ni->creation_time = <creation_time_I_need_to_set>
ntfs_inode_sync(ni); ---> this I thought should write out the changed inode.

The ntfs_inode_sync() does not return any error. However the creation time is still not set correctly. It takes the creation time as the current time and not the one set in the ni->creation_time.

Is there anything else I should be doing to set the creation time ?

Hi,


It might be useful to mount the file system as rw.

The usb is mounted as rw --

/dev/sda1 on /localdevices/JetFlash_Transcend_4GB_TXJEQD75 type fuseblk (rw,allow_other,blksize=4096)

Hi,

You might try ntfs-3g-2009.4.4AC.15 from http://pagesperso-orange.fr/b.andre/adv ... g.html#new

Thanks Jean-Pierre. I downloaded the source for the 2009.4.4AC.15 version and installed it.
The mounting of the NTFS USB goes fine. However when I try to access the mount point it gives

bash# mount -t ntfs-3g /dev/sdd1 /mnt/
bash# ls /mnt
ls: /mnt: Input/output error


I was checking the logs and here is what I found -
Aug 3 16:29:43 l13 ntfs-3g[29842]: Version 2009.4.4AC.15 integrated FUSE 28
Aug 3 16:29:43 l13 ntfs-3g[29842]: Mounted /dev/sdd1 (Read-Write, label "Transcend", NTFS 3.1)
Aug 3 16:29:43 l13 ntfs-3g[29842]: Cmdline options: rw

Aug 3 16:29:43 l13 ntfs-3g[29842]: Ownership and permissions disabled

Do these logs indicate that the integrated FUSE version is 2.8 ?
Because I have the fuse version 2.7.4 installed. Is that causing the conflict and so it is giving the input/output error ?

I tried with the earlier version of ntfs-3g too which is ntfs-3g-2009.4.4AR.1 and with this version the mount goes fine and I can access the mount point too.
Why does it not work with the version 2009.4.4AC.15 ?

Thanks.

Mounted the USB with the debug option. Here is the debug information --

It keeps giving "fuse: writing device: Invalid argument" as the error. What could be the issue given the fact that this works fine with other versions of the ntfs-3g driver ?

Hi,


Yes, this is the most likely cause. In 2009.4.4AC.15 I integrated a long awaited fuse patch for not applying the umask when there is a default ACL, and this implied an interface change.

In the recently released version 2009.4.4AR.16 I made this interface upgrade conditional, so that people not interested in Posix ACLs need not upgrade fuse. If you upgrade to ntfs-3g-2009.4.4AR.16 it should be ok. Alternatively, you may try to upgrade the fuse kernel module, the shell script for that is available in http://pagesperso-orange.fr/b.andre/fuse-module.tgz
