Poor man's approach:

1) single user mode
2) remount root readonly
3) run resize2fs - force it to proceed despite (warranted) dire warnings
4) switch root (remount won't be good enough since it changed "underfoot")

Of course, while technically "mounted", it might as well be unmounted
since you can't keep running applications.
