What are the original sizes? What sizes are you trying to shrik them to?

Did fsck it after shrinking the filesystem? I think that shouldn't be
necessary, but might as well do a health check :).

What was the actual error message? Error 5 just a bit generic...

You should be able to mount any filesystem that isn't mounted.

Some mounted filesystems can be resized as well, with a higher risk of
testing your disaster recovery procedures.
