I don't think this was wheel-spinning so much as yarn-pulling, finding interesting tid-bits and seeing where they go. The most interesting things (to me) are when something doesn't quite line up with expectations, and then digging until I understand what the difference was - usually I misunderstood something (or failed to recall something, like in this case, disk/filesystem caches) - and I find myself more enlightend.
I totally get doing this to learn because it was an interesting process. But yea, if this were for money? I'd just restore from backups and follow the SOP - because for money, the _why_ something failed is often unimportant, the remedy is the same -- reboot, replace, correlate, correct.
Playing with Schrodinger's stuff. The storage industry/equipment lies so pervasively, even when it's working as intended
More importantly, perhaps, is this is a "brain worm" being spread to others. Not to armchair too much, but there's a certain responsibility by publishing your writing.
I'd hope for more dutiful research before publishing/risking data with anything even remotely nearing suggestion. Loud/clear warnings.
We're all playing the Telephone Game whether we want to or not.
