files on ext. HD change their ownership by themselves ?!

Hi,

I just connect my old 105-MB hard disk as a second disk to my NeXTstation.
All worked fine up to the moment I recognized that the ownership of all
files had been changed to fifi.nogroup (my own id is fifi.fifi). I restored
the ownership, checked it and continued working. After a while I again
looked for the files on the second hard disk and - damned - the ownership
had been changed to fifi.nogroup again.... Can anyone tell me, why that
happens and/or which task does it? (I'll kill it :-))

Thanks, Axel

This belongs on comp.sys.next.sysadmin, so I've set the net news header  
line "Followup-To:" accordingly.

you need to have an entry in the file called /etc/fstab for both drives,  
otherwise the automounter resets ownership of files on drives that are not  
the boot drive. This happens when you log in (right?).

Put a second line into /etc/fstab like this:

/dev/sd1a	/OldDrive	4.3 rw, noquota	1 2

To learn more about this, launch Digital Librarian and search the UNIX man  
pages for fstab and mount and umount

and don't forget the command "mount -p" for those times when you can't  
remember the syntax of the lines you have to put in /etc/fstab!.

By the way, before you diddle with /etc/fstab, since you'll have to log in  
as root, make a copy of /etc/fstab first (call it something like  
fstab.original) and then edit /etc/fstab.

	Good luck

Thanks for all the answers, the reason had been that I left the second
hard disk under control of autodiskmount. Solution: creating a correct
entry in /etc/fstab by running (for example) 'mount -p > /etc/fstab' and
rebooting the system. Since that all works fine.

Regards & Thanks, Axel

I noticed something similar a while ago.  I attached an external
drive to my machine and found that whenever I logged in I owned every 
file on the external drive.  If I logged in as root then root owned
every file on the external drive.  This was confusing to say the
least.  What I found, though, was that NeXTStep mounted the external
disk when I logged in.  Thus, it made sense that I owned it since my
login shell mounted it.  i fixed this by making an entry in
/etc/fstab so that the Next mounted the External drive when it
booted. 

I hope this helps solve your problem,

You need an fstab entry for the disk...
something like this:

/dev/sd1a /<mount-point> 4.3 rw,noquota 0 1

You need to change <mount-point> to the path of where you have the disk  
mounted.

The same thing has been happening to me lately. The ownership of my  
external HD and everything on it changes to whoever loged in last.  It  
must not be happening every time, though, because I found out when I was  
told that I didn't have permission for a file on the external that I use  
often.  I checked into it and found that everything was owned by one of  
the other users on my machine.  It seems like it happens often, but not  
every time.  I'm root here too, so the other usrs aren't doing it.

Hummmm......

The same thing happened to me.  I added my external drives to /etc/fstab
so that they mounted on start-up rather than mounting when I login, and
that fixed the problem.
