Well, I just didn't hit 'y' long enough.

Re-running the fsck with '-y' completes after asking 472876 times.  Note in
the fsck_lfs messages below that it claims no space for lost+found, yet the
partition is significantly larger than the data being written to it (it
should have ~100G 'extra' space on the LFS partition).  Re-running fsck
again and again yields the same results.


Additional data from that run, done passing '-d' to fsck_lfs:
