 This error doesn't occur when passing a block size of 32768 to newfs.
 Debugging fsck_ffs, the following mismatch is seen with the
 inconsistent filesystem:
 
 Starting program: /sbin/fsck_ffs /dev/md0
 ** /dev/md0
 ** Last Mounted on
 ** Phase 1 - Check Blocks and Sizes
 ** Phase 2 - Check Pathnames
 ** Phase 3 - Check Connectivity
 ** Phase 4 - Check Reference Counts
 ** Phase 5 - Check Cyl groups
 
 Breakpoint 1, pass5 () at /usr/src/sbin/fsck_ffs/pass5.c:352
