On a standard btc node, I had a problem akin to that of https://bitcointalk.org/index.php?topic=5319613.0 so went to reindex with a './bitcoind --reindex' and the daemon seems unable to download 100% of the blockchain. I started the command about a week ago, and for the past ~4 days it has been stuck right around 90.8%. Not that the daemon does not continue to attempt, but the percentage downloaded fluctuates between ~90.65 and 90.90%.

I have found a few related issues on the stackexhange that say this could be due to faulty peers or even a storage issue, but neither of these seem immediately apparent. Beyond this, several answers report that the reindex cannot be cancelled, so I am unsure of how to solve this issue. Is my node fried? Is there a way to change my 'dbcache' mid download (as https://bitcoin.stackexchange.com/questions/38422/possible-to-speed-up-reindex gives this as a potential alleviation, though without specifying the location of dbcache)?

Any info on the above would be significantly appreciated as I attempt to re-activate my node.
