Ok, Bitcoin Core is open and doing Reindex. nothing to see.
What is that? vv181
Does not work for me in cmd

Thanks a lot.

Yeah, there is nothing to show in cmd. The command you entered on cmd is meant to open up Bitcoin Core (bitcoin-qt) with some additional configuration.

The -datadir=<dir> is a config to specify the data location of your Bitcoin Core, and what the -reindex did is to rebuild your block index and chain state(or to simplify it, it rebuild the blockchain).

As why the problem arises, it is likely caused by the power outage when you are still syncing. So the PC got unclean shutdown, and the data got corrupted because of it. You can see that in the debug.log you posted:

Code:

2021-11-27T22:36:53Z Opening LevelDB in E:\Bitcoin\blocks\index
2021-11-27T22:36:53Z Fatal LevelDB error: Corruption: 41 missing files; e.g.: E:\Bitcoin\blocks\index/000313.ldb
2021-11-27T22:36:53Z : Error opening block database.
Please restart with -reindex or -reindex-chainstate to recover.

So, if your Bitcoin Core is opening up and it reindexing, it should be good to go. It will rebuild the blockchain and will continue to sync it.

On a side note, how much RAM do you have available? If you have a pretty much available ram you might want to bump up the dbcache, it will speed up your syncing process.

It works, thank you. Wink

Synchronization has now been recorded. Still 9 years behind. The synchronization will take 3 days. How do I increase the dbcach?
I have 8 GB of RAM.
