Title: [SOLVED] Problem saving files using ntfs-3g
Post by: SinoTech on June 20, 2009, 02:07:54 am

Hi all,
I use a NTFS partition to share sources between linux and windows. To mount this partition on linux I use ntfs-3g. When I mount this partition as user "user1" I'm unable to save files to this partition in codeblocks as "user2". As the ntfs-3g driver does not support permissions, the permissions are always set to "rwxrwxrwx". So all users should be allowed to create, update and delete files. In fact, using the bash (or the offical codeblocks release 8.02) saving changes to any file works. It's only the current SVN head that tells me that saving files did not work.

- Official release works with normal linux filesystems (ext2, ext3, ...) as well as with my NTFS partition.
- Latest SVN head works with normal linux filesystems (ext2, ext3, ...) BUT NOT with my NTFS partition.

So I'm wondering why latest SVN head tells me that it can't save changes to a file while prior versions successfully do. Also, as it works with other filesystems I'm wondering if that is a problem of NTFS-3G or codeblocks. Any help is appreciated.

Cheers,

Sino

The problem is in the wxWidgets-function we use while saving files.

See my explanation here: http://forums.codeblocks.org/index.php/topic,10263.msg70971.html#msg70971 (http://forums.codeblocks.org/index.php/topic,10263.msg70971.html#msg70971)

What I said there for vfat is the same for ntfs3g.

If I mount a ntfs-partition with the following fstab-line at boot time, it works:

Code

/dev/sda2   /windows/xp    ntfs-3g defaults,locale=de_DE.UTF-8     0       0

a call to mount now gives the following:

Code

/dev/sda2 on /windows/xp type fuseblk (rw,allow_other,blksize=4096)

That's no help for vfat user, at least not with the default filesystem-driver.
I don't know if a fuse-driver for vfat exists.

Thank you for the fast answer. Seems as the problem was that I've added the "uid=...,gid=..." options to my fstab (thought it's a good thing to have all files/directories owned by my local user). After removing that options it works fine. Problem solved.
Keep up the great work :-)

Cheers,

Sino

thanks for the answer, after editing the fstab file it works fine

the old fstab line, which did not work:

Code

UUID=5A50F6AB50F68CCF   /media/data   ntfs   defaults,umask=007,gid=46           0  0

and the new one: I (uid=1000) am the owner

Code

UUID=5A50F6AB50F68CCF   /media/data   ntfs   defaults,uid=1000,gid=46,umask=007  0  0

or this: everbody gets full access

Code

UUID=5A50F6AB50F68CCF   /media/data   ntfs   defaults,umask=000                  0  0
