You've missed the point of this sub thread discussion, or I did.  He
stated that having the metadata show the files still exist is a positive
thing.  The files are gone.  I stated that this discrepancy is not good

I believe you are confused, thinking this micro discussion is dealing
with the OP's overall situation.  It is not.  It is dealing strictly
with the issue of the lost set of disks, the files that were on them,
and the fact the metadata says they still exist.  I believe this is due
to the fact that he hasn't run a destructive xfs_repair yet, which I'm
guessing will remove those orphaned metadata entries.

Again, I'm pretty sure you misunderstood exactly what we were talking
about, or I misunderstood what he was talking about, heck, maybe both.
I absolutely was not stating anything akin to throwing the baby out with
the bath water.
