      1) Create the uncorrupted database(attached as uncorrupted.tar.bz2):

      ./mongod --directoryperdb --dbpath corruption --storageEngine wiredtiger
> use db
switched to db db
> db.collection.insert({data: true})

      2) Set up database db for mdb-wt:

      sajack@linux-p7yj /home/sajack/mongo git master () % cd corruption/db
sajack@linux-p7yj /home/sajack/mongo/corruption/db git master () % ls
collection-0--6386865262002950881.wt  index-1--6386865262002950881.wt
sajack@linux-p7yj /home/sajack/mongo/corruption/db git master () % ln -s ../WiredTiger.wt .
sajack@linux-p7yj /home/sajack/mongo/corruption/db git master () % ln -s ../WiredTiger.turtle .

      3) Find offsets with mdb-wt

      sajack@linux-p7yj /home/sajack/support-tools/mdb-wt git master () % python mdb-wt.py -p ~/mongo/corruption/db/collection-0--6386865262002950881.wt

0000301c: block sz=0x1000 cksum=0xf2e0bde0 flags=0x1(cksum)

      4) Corrupt the database (attached as corrupted.tar.bz2)
      Open ~/mongo/corruption/db/collection-0--6386865262002950881.wt with a hex editor
      Change hex value 0x61 at 0x1044 to 0x62
      Save

      5) Run mongod --repair

      sajack@linux-p7yj /home/sajack/mongo git master () % ./mongod --directoryperdb --dbpath corruption --storageEngine wiredtiger --repair
      Show

      Manually flipping a bit in a WiredTiger database causes a mongod using it to fail to turn on. Executing mongod again with --repair will produce the same error.
