Re: Corentin Mercier @merc1er stolen $1,000 in Bitcoin

I have not "stolen" anything. This guy gave me $1000 (harassing me on Telegram and calling me at night to get my BTC address) to look at his crappy code, which I did. He replied things that made absolutely no sense when asked about his code, which is probably not fixable at this point...

If anyone has issues with bitcash, open an issue at https://github.com/pybitcash/bitcash

For the record, I sent this guy $1,000 worth of BTC: https://blockchair.com/bitcoin/transaction/90441b99bb0646750a61ffb119a4823db72941c2578d6ae23a7a270f17e1a62a

Re: Bitcoind stops while syncing - "Failed to open mempool file from disk"

It's very slow IMO, but i guess it's better than can't sync properly.

Depending on percentage free RAM, you could increase dbcache or/and maxsigcachesize number slightly (between 5-25%) if you want faster sync and prepare to take risks. If you have PC/notebook, you could sync from it and on Pi you just need to wait for block verification.


Indeed, 17% after 2 days. I increased -dbcache by 25% but RAM went over 95%.
I will be playing with the arguments to reach a faster stable syncing.

So it has been syncing overnight and I am now at 11%.

Bitcoind RAM usage remains at about 50% (500MB). Looks like it's working! Thank you for the support.  Wink

Okay so I am giving it another try with the following parameters:

Code:
bitcoind -daemon -maxmempool=100 -dbcache=200 -maxsigcachesize=4

I tried with -dbcache set to 50 but the verification progress (syncing) was way too slow!

It seems to be syncing a bit slower than before with the current parameters but let's hope it keeps the RAM usage below 80%.

Since v0.6, C-Lightning does support running on top of pruned nodes, and the doc I provided is not only for pruned nodes (for instance just lower the `dbcache` would reduce the RAM usage).

Oh that’s interesting! I will look into it, thank you.

You might want to take a look to https://bitcoin.org/en/full-node#reduce-storage (there are options to reduce traffic too).

I do need to run an unpruned node as my goal is to run a lightning node  Lips sealed

It stopped with the following at the end of `debug.log`:

I rebooted the raspi and it went straight to recovery mode... I will start from scratch again and do the hardware checks mentioned above.

Thank you! I didn't specify such thing.

It's now re-syncing (about 2%). Let's see if it goes through.

delete the blocks and chainstate folders and restart bitcoind.

It restarted from the first block already, but i'm trying this one more time.

@darosior I changed ownership to `pi` and chmod-ed the hard drive mount. Does bitcoind use a specific user that I need to change to?

Also, note that I didn't specify a path to save the block chain to bitcoind - instead, the folder .bitcoin links to my drive.

I installed Bitcoin Core on a Raspberry Pi and tried to sync the block chain using bitcoind.
The data is written on an external hard drive (1TB) mounted on the machine.

After I run the `bitcoind -daemon` command, the block chain starts syncing, but after a few hours it stops.
This is what I have at the end of the debug.log file:
