mckusick bd94887961 Yesterday I had to fix a badly broken disk, and found that fsck kept dying: 
DIR I=64512 CONNECTED. PARENT WAS I=4032
  fsck: cannot find inode 995904

fsdb found the inodes with no problem:

  fsdb (inum: 64512)> inode 995904
  current inode: directory
  I=995904 MODE=40777 SIZE=512
        MTIME=Feb 14 15:27:07 2000 [0 nsec]
        CTIME=Feb 14 15:27:07 2000 [0 nsec]
        ATIME=Feb 24 10:31:58 2000 [0 nsec]
  OWNER=nobody GRP=nobody LINKCNT=4 FLAGS=0 BLKCNT=2 GEN=38a41386
  Direct blocks: 8094568 0 0 0 0 0 0 0 0 0 0 0
  Indirect blocks:  0 0 0

The problem turns out to be a program logic error in fsck.  It stores
directory inodes internally in hash lists, using the number of
directories to form the hash key:

        inpp = &inphead[inumber % numdirs];

Elsewhere, however, it increments numdirs when it finds unattached
directories.  I've made the following fix, which solved the problem in
the case in hand.
