Can't change ownership of files on windows partition

alan_the_eagle · 03-26-2005, 05:08 PM

Hi

I'm running RedHat Enterprise (not sure which version but think it is 9). I have 3 main partitions:-

Windows OS
Data
Linux OS

I have the Data set up as D:\ on Windows and mounted in two locations in Linux. I have it mounted as /mnt/win/d and that works perfectly. I also have it mounted on /home/alan/Data - this works apart from I can't delete anything!

The files are all shown as owner root but chown fails 'changing ownersip of xxx: Operation not permitted'

fstab is as follows, what am I missing - as far as I can see both the mountings are the same.

Thanks!

Alan

it's not permitted, no.. where do you suppose that information would get held?? fat32 certainly can't handle that sort of information. you need to specifiy the ownership for the *whole* device on mount. everything has the same owner and group.

OK - I see.

But even though the owner is root I can use Nautilus as a user and delete folders that are mounted on /mnt/win/d but not on /home/alan/Data.

These two lines appear to be the same to me:-

/dev/hda5 /mnt/win/d vfat defaults,umask=000 0 0
/dev/hda5 /home/alan/Data vfat defaults,umask=000 0 0

so I don't understand where the difference is coming from.

Mounting the same filesystem to two different locations doesn't sound like a good idea. I think what happens is that the second entry in your fstab is automatically mounted read-only because the fileystem is already mounted writeable elsewere and mounting it writeable again might mess up something (just guessing though). Why don't you make /home/alan/Data a symlink pointing to /mnt/win/d?

oh blimey.. yeah that's a seriously bad idea. if you really want them accessible in both locations, then just use a symlink found one mountpoint to the other.
