RH 8.0 don't let me change attrib by chmod command

Hi all,

I am using RH 8.0, when I install it, I added a mount point to my FAT32 partition, can the mount point called "win_b"

I can read this partiton, but can't write by login as general user, only root can write to "win_b"

Then I login as root and then type the command

#chmod 777 /win_b

It show me than

chmod: changing permissions of `/mnt/win_b' (requested: 0777, actual: 0755): Operation not permitted

What is wrong on my RH 8.0??

You can't use chmod on a VFAT partition - so nothing is wrong with your RedHat! If you want others to be able to access the mounted partition check the manpage of mount:

Quote:

Mount options for fat
(Note: fat is not a separate filesystem, but a common part
of the msdos, umsdos and vfat filesystems.)

blocksize=512 / blocksize=1024 / blocksize=2048
Set blocksize (default 512).

uid=value and gid=value
Set the owner and group of all files. (Default: the
uid and gid of the current process.)

umask=value
Set the umask (the bitmask of the permissions that
are not present). The default is the umask of the
current process. The value is given in octal.

Add your VFAT partition to the /etc/fstab file. This will allow any user to write and it will mount on boot

/dev/hdxy /mnt/win_b vfat user,auto,umask=000 0 0

Change hdxy to your actual partition
