Yes, --rebuild-tree rebuilds the entire filesystem, so if it fails the
filesystem is not accessible because the old tree is no longer available.
This situation remains until a successfull rebuild has been done, so
investigate what the cause of the failure is and try again.

This is, of course, an extremely... peculiar design. The robust approach would be to build a new tree in parallel with the old (as long as space was available and the old tree was undamaged enough to determine which blocks were free), then switch over to the old atomically.

This is harder, but it does make the thing fail-safe.
