Not sure how much edge you're talking about. PL Construction
adhesive/Liquid Nails will hold it. Get it under as far as you can. Masking
tape around and be prepared to clean up any that oozes out with the
recommended solvent. Once it dries it's "mechanical method" to remove any
unwanted adhesive. Put some weight on the area until it dries. Piece of
waxed paper between the weight and lino will keep the weight from adhering
to the floor but you shouldn't have exposed adhesive anyway.
Before you start driving yourself crazy attempting to reglue, do the
icepick test in the exposed crack, and from below if you have access.
Make sure subfloor isn't mushy already, a common side effect of that
joint failing. If subfloor is mushy, may as well bite the bullet and
repair it all properly.
