can't change permission under ntfs mounted fs

idnotcrae · 07-25-2011, 04:51 AM

when i try to change permission for any file under mounted ntfs partitions (without any errors) it remains the same after changing.

#cat /etc/fstab

Quote:

/dev/sda3 swap swap defaults 0 0
/dev/sda4 / ext4 defaults 1 1
/dev/sda1 /win/C ntfs-3g fmask=111,dmask=000 1 0
/dev/sda5 /win/D ntfs-3g fmask=111,dmask=000 1 0
#/dev/cdrom /mnt/cdrom auto noauto,owner,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0
tmpfs /dev/shm tmpfs defaults 0 0

Correct because it is an ntfs filesystem.. I believe it defaults to 777 when viewed from *nix.

CD into the mounted directory and do ls -l

And it should show everything as rwx rwx rwx

i guess i made the permissions for them during installation and they was read and write permission and most of them are read and write ,, but this is not the problem , it's that i can't cahnge the permissions to them

Have a look at this http://slackwiki.org/Windows_Partitions and note the funny 'rw'.

i can't add execution to files in ntfs partiion.
I download pkgs to ntfs partition cuz i have free space their, and i can't run the SlackBuild scripts because it don't has execute permission under that ntfs (and can't be added due to some reason uknown to me) ,i must move move the pkg to root partition and change the permission then run it.
i wanna know how to add execution to files under ntfs fs.

You need to understand that the file permissions on NTFS do not map directly to Linux file system permissions.
If you need more space for your Linux, then shrink the the NTFS partition (ntfsresize is your friend) and convert that to a Linux compatible file system.

i think i'll be a good friend with ntfsresize if it will not wipe my data out !! is their a chance to resize NTFS without loosing data ?

From 'man ntfsresize'

Quote:

The ntfsresize program safely resizes Windows XP, Windows Server 2003, Windows 2000, Windows NT4 and Longhorn NTFS filesystems without data loss. All NTFS versions are supported, used by 32-bit and 64-bit Windows. Defragmentation is NOT required prior to resizing because the program can relocate any data if needed, without risking data integrity.

It has not failed on me yet!
