[ale] HOW2 link a partition to another disk's partition ?

[Jeff Lightner]

I don't think that will do it either. 

It sounds like the desire here is to have 1 directory that has the space
of both partitions.  If that's the case then it's a perfect candidate
for LVM which would allow combination of the two partitions into a
single volume group and then creation of a single logical volume that
would encompass all that space.

Of course temporarily the files would have to be moved to someone
outside of both partitions (backed up) then restored after the LV
creation.

Ahhh, that wasn't entirely clear in your earlier email.  What you need
to do, now that you have move the contents of /drive1/home/* elsewhere,
is to now remove the directory /drive1/home and then softlink (ln
-s) /drive2/home to /drive1/home like this:

   rmdir /drive1/home
   ln -s /drive2/home /drive1/

This assumes that /drive1 and /drive2 are the mounted file systems and
that "home" is a directory on each of those file systems.

hth,
