I'm not aware of any reason to avoid links to files. However, current CIFS security does not allow CIFS clients to follow links that leave the share on which they originate, so that it is not possible to follow a link to another volume (unless that link is to another share, which is why it works for homedirs). This is being tracked by BURT 15808.
If you want multiple volumes (or filers) to be accessed from a single point, you can use DFS to achieve this for CIFS clients.

Symbolic Links on directories are ok; you should prevent links on files.
Relative Symbolic Links could followed by cifs clients.
you have follwing options for the behaviour: options cifs.symlinks.enable on/off options cifs.symlinks.cycleguard off should prevent .,..-troubles
i think you could also try to use absolute sybolic links with /etc/symlink.translations .

We want to do someting smart to limit the number of mountpoints for our Netapp users, and to make admin more easy. Question is: "Is there a way to let the filer tell cifs and nfs -boxes
to follow links
pointing between volumes ,in the same way as they do
concerning homedirs? "
On our Netapp 760 running 6.1.1R1 we have 2 big volumes for
projects :
/vol/vol0/proj1 -access=eto-hosts,root=grimstad1:bagri1 /vol/vol1/proj2 -access=eto-hosts,root=grimstad1:bagri1
the same volumes are also cifs shares: PROJ1 /vol/vol0/proj1
Prosjektkataloger (PROJ1)
everyone / Full ControlPROJ2 /vol/vol1/proj2
Prosjektkataloger (PROJ2)
Tried this experiment to limit the users to mount just
/vol/vol0/proj :
Made a /vol/vol/vol0/proj directory, containing links :
# ls -l /fagri2/vol/vol0/proj/
lrwxrwxrwx 1 root other 19 Aug 9 15:59 adm ->
/vol/vol0/proj1/adm
lrwxrwxrwx 1 root other 20 Aug 9 15:59 alex ->
/vol/vol0/proj1/alex
lrwxrwxrwx 1 root other 19 Aug 9 15:59 aps ->
/vol/vol0/proj1/aps
. . .
and a new cifs share:
proj /vol/vol0/proj everyone / Full Control
Mounted /vol/vol0/proj on a unix workstation, and it sees
only links ,
win2000 and NT doesnt even understand what to do with a link....
....so this is probably not the way to do it...
-any good ideas?
Torkel.
