1002030001 - Commit failed when making or checking permissions after firmware 6.7.5 update

Interesting thoughts during recovery:

I decided to try the non-brute-force approach to this.

In a good twist of fate, my last backups ran about two hours before the fault on the 11th. This rarely happens. I unmounted the backup drives from the NAS. Then, I set up my old NAS (Ultra 4) and started copying files over from the problem NAS. I quickly realized a number of my folders were inaccesible. I copied the two (of 10) which i could and then performed a Reinstall OS, as I had read if fixes some security issues on the data volume.

Interestingly, when I rebooted, all of my folders were accessible again. I immediate started a copy of the remaining 8 folders. My optimism was short-lived, though, as, while the length copy took place, several of the folders became inaccessible again. I've managed 3 more folder sets. I'm going to try the OS reinstall again once they complete and see if I can get the remaining folders. If not, I'll rely on backup.

Once the data transfer is done, I'll do a full factory reset on the current NAS and then move some content back in and watch it like a hawk.

Will update so future generations have a path forward.
