How can I change the mount options for a drive?

[gunhorde]

I've got an external Lacie firewire drive and I need to change the mount options for my users. The current default settings for mounting it are:

/dev/disk2s4 /Volumes/Data (local, nodev, nosuid, journaled)

I need to remove the 'nosuid' flag from the drive to allow user and group permissions to be altered by my end users.

Any assistance would be greatly appreciated

UPDATE - The drive is in Mac OS X format, not native UNIX. Is this a problem for what I want to accomplish?

You will need to drop down the command line and use the mount command to mount it normally. A quick "man mount" should reveal how to set the options...

can I automate that?

I know how to manually alter it, but I want to make it permanent and automatic. The file '/etc/fstab' exists, but is it used? The current file is empty except for several commented out examples.

UPDATE - The manual option doesn't work for some reason, I get the error "Incorrect super block" when I use the mount command.

from the command line, 'mount' shows the following for my device:

/dev/disk2s4 on /Volumes/datastore (local, nodev, nosuid, journaled)

I can unmount the device with umount /Volumes/datastore, it works fine.

When I attempt to remount the device, I get the error mentioned above. The mount commands I've tried are:

mount /dev/disk2s4 /Volumes/datastore
mount -t ufs /dev/disk2s4 /Volumes/datastore
mount -t ufs -o local,nodev,nosuid,journaled /dev/disk2s4 /Volumes/datastore

All commands produce the same error message, or a useage message. A reboot remounts the device just fine.

The command mount -a also has no effect

I've also created an entry in the blank /etc/fstab file with mount options, it's ignored apparently, there is no change after a reboot; the device is mounted with the original options intact.
