Yay! Finally after about exactly one month I finally am able to mount

Got to love the open source. =) I downloaded ceph source code. Built them. Then tried to run ceph-objectstore-export on that osd.4. Then started debugging it.

Oh that "1" that didn't make sense was from the corruption happened, and that struct_v portion of the data changed to ASCII value of 1, which happily printed 1. =P Since it was a mount
portion... and hoping it doesn't impact the data much... went ahead and allowed those corrupted values. I was able to export osd.4 with journal!
congratulations and well done :)
just imagine tring to do this on $vendors's propitary blackbox...
