[1500 TH] p2pool: Decentralized, DoS-resistant, Hop-Proof pool

[echris1]

The freakin' block index is now > 15GB when bitcoind is running. This is getting to be insane...

My whole Bitcoin folder is only 1.7GB...

I know, right?  This totally sucks.  Bitcoin is taking up all the space on my hard drive.  I mean, I only have a 10 GB hard drive...  oh wait, no I have a 2TB hard drive and the block chain is an insignificant blip on its radar.  Nevermind.

It could eventually be a problem for people running off of flash drives.  But those aren't expensive either, or do what I do and use an old HDD for your P2Pool and bitcoind.

[kjj]

My p2pool nodes are running bitcoind in RAM.  I expect this will continue to be practical for quite a while.

[ChanceCoats123]

In my dedicated miner, I have 4 gb of ram, and an 80gb HDD. There were 15 gb free on my partiton and neither bitcoin-qt nor bitcoind would run. Bitcoind at least gave me an error so I could know what was up... The error read "not enough space." I believe that when you have bitcoind actively running, it consumes much more space than when just checking the folder size. I was running bitcoin-qt on my main rig (separate from my miner) and was filling my SSD. I stopped running and now have ~ 15gb free.

and you think it was the blockchain taking up the space?

I'm not sure if you're being sarcastic... But my serious response is yes. I didn't change any programs but I stopped running bitcoin-qt (because I was keeping track of my payments). And now I coicidentally have an extra 15GB of space. And now bitcoin won't open back up on this computer because there is not enough space available in the C:\users\appdata\roaming\bitcoin folder for the blockchain data.

admittedly, there was a little sarcasm there, but not much.

it doesn't necessarily mean the blockchain is that big tho. there could be other temporary work files that get created while it is running, and you may have more than one copy of the blockchain while it runs so you always have a safe copy.

unless you're checking filenames and their associated file sizes at the time the program is running, and again when it isn't running, you don't have enough info to know it is the blockchain.

windows 2008 r2, ubuntu linux proxyserver used with the same result Core i7 920 8 GB HDD SSD vertex 3 max iops 100 Mb internet dedicated ip. what is the maximum number of connections? Cgminer shows four sets proxy connection - 40*4=160 connection

Lomax,

I don't know, I don't think 2008 has this kind of limits, anyway see this:

That's true. I was incorrect in my first statement that it was the blockchain which takes up that space, and should have realized it was simply bitcoin-related files.

[bitpop]

What bitcoin related files? Does your hd contract when you start bitcoin? I dont think mine does that.

well, one idea, is unless he's running with statically created swap space (which I do to avoid fragmentation), then his windows might be expanding and contracting his swap file on demand, which could be eating up some of that empty space.

What Bitcoin related files?

My bitcoin folder(s) + all virtual memory is <2 GB.

The only thing I can think of is you have an excessively long log file?  in the datadir folder there is a sub folder called "database" which contains the log. You can safely delete the log files to reclaim space (I wish bitcoind had an option for max log where it would truncate oldest log file to maintain a max size).

hey guys.

so i've been using p2pool fine for a couple weeks now with my meager, just for the heck of it 80m/hash, but for reasons beyond me, on the 14th it stopped actually generating payments. p2pool's still running, ufasoft miner's running (via gui miner, for cuda mining on my nividia (it's what i have for now.)) and both appear as though all is well... any ideas?

i will gladly post screenshots and such if need be, but as i said, it appears as though it's all working. i don't think there were any changes to the system since then either.

With just 50 Mhash/sec, you might have just been unlucky enough not to have any shares in the last few blocks.

In your p2pool logs, look for these numbers:

Local: X MH/sec ... Expected time to share: Y hours.

X should be somewhere near 50, and Y is probably around 12 hours.

[arklan]

that is indeed the case. i'm sure it doesn't help this isn't a dedicated miner... ok, well, i'll stopp worrying about it then. thanks.

[DeathAndTaxes]

Are you using a static payment address?
If the address listed here: http://p2pool.info/ (under current payouts)?
What does p2pool daemon show as "Current Payout"?
What does p2pool daemon show as pool hashrate "Pool: XX GH/s"?

[arklan]

yea, static payment.
pool is showing 314ghash
current payout 0.0000

and no payment is listed for my address.

but now i know where to check. thanks.

[TheHarbinger]

With only 80Mh/s, it is very possible that you did not have any found shares in the last 24 hours.  Since p2pool calculates payouts based on the number of shares in the 24 hours prior to a found block you would have a zero payout.   But on the other hand, tomorrow you could find 4 shares, and be like Rick James, rich bitch!   

[arklan]

yea, now that i've thought about it, i realize that's likely what happened. thanks guys.

Hmm someone has an interesting idea of what rich means ...

Of course once you know that you missed a day of payment, there is of course no memory in the process of share calculation, so there is also no guarantee that you will ever get that day back ...

[arklan]

well like i said originally, only 80mh, the payment is really basically costing more then my electricity anyway, so, oh well to the lost day.
