error: "Disk space is low!", ignoring disk space limitations

[nikitasius]

Describe the issue

Program ignore disk space limitation, what i set up on start

Can you reliably reproduce the issue?

If so, please list the steps to reproduce below:

1. start bitcoin-0.14.2/bin/bitcoin-qt
2. select checkbox what you want to limit data to 1024Mb (~6 days)
3. bitcoin use all disk space (~16Gb in my case) and throws an error.

Expected behaviour

Program syncing a blockchain using only 1Gb of free space on my hdd

Actual behaviour

Even if i selected to limit disk space to 1024Mb, program used all available space. folder .bitcoin/blocks/have size of 16Gb.

Does a bitcoin_rw.conf file exist? Can you post its contents?

[nikitasius]

Does a bitcoin_rw.conf file exist? Can you post its contents?

I wiped all (software, config, .bitcoin folder). I will try it again and i will tell you resultats.

[nikitasius]

Well..

error: http://i.imgur.com/BzvpCWr.png blocks folder: http://i.imgur.com/KVswpaQ.png before: /dev/sda2 717G 665G 16G 98% / after: /dev/sda2 717G 681G 51M 100% /

Settings on start: http://i.imgur.com/5NJUVfq.png

Thats how i start it: ~/patatipatata/0_btc/bitcoin-0.14.2/bin$ ./bitcoin-qt

patatipatata - ecryptfs folder.

There is no bitcoin_rw.conf file (not in .bitcoin folder and not in ~/.config/Bitcoin) there is only Bitcoin-Qt.conf file: Bitcoin-Qt.conf.txt

[nikitasius]

i got some free space and.. before /dev/sda2 717G 544G 137G 80% / after (not finished yet) /dev/sda2 717G 586G 95G 87% / Looks like this software really don't care about "use 1Gb or 4Gb and not more setting".

[nikitasius]

well well well. idk what the fuck with this software

You select 2048 Mb, it continue and continue download. Damn i no need this 150 Gb of blockchains.

Since 7 jul no info -.-

[luke-jr]

Check ~/Library/Application Support/Bitcoin/

[nikitasius]

I dont have such folder

nikitas@pentagon:~/Downloads$ cd ~/Library/Application Support/Bitcoin/
bash: cd: /home/nikitas/Library/Application: No such file or directory

btw reached 5.1Gb

[nikitasius]

here is file what was running now https://bitcoinknots.org/files/0.15.x/0.15.0.knots20170914/bitcoin-0.15.0.knots20170914-x86_64-linux-gnu.tar.gz

[luke-jr]

Sorry, your theme made me think you were using Mac.

On Linux, the directory is ~/.bitcoin

There should be a bitcoin_rw.conf file in it...

[nikitasius]

well..

nikitas@pentagon:~$ ls ~/.bitcoin
ls: cannot access /home/nikitas/.bitcoin: No such file or directory
nikitas@pentagon:~$ ls ~/.config/Bitcoin/
Bitcoin-Qt.conf
nikitas@pentagon:~$ ls ~/patatipatata/0_btc/.bitcoin/
banlist.dat  chainstate  debug.log          mempool.dat  wallet.dat
blocks       db.log      fee_estimates.dat  peers.dat
nikitas@pentagon:~$ 

[luke-jr]

That's odd. Are you setting $HOME or -datadir when you run Bitcoin Knots? Why is it using ~/patatipatata/0_btc/ for the .bitcoin directory?

[nikitasius]

nope, i should?

clean run:

1. i downloaded https://bitcoinknots.org/files/0.15.x/0.15.0.knots20170914/bitcoin-0.15.0.knots20170914-x86_64-linux-gnu.tar.gz
2. i unpacked it into ~/patatipatata/0_btc/
3. i open terminal in ~/patatipatata/0_btc/bitcoin-0.15.0/bin
4. i run ./bitcoin-qt

next i setup as

and some time after i have

patatipatata - ecryptfs area.

[nikitasius]

still increasing

[luke-jr]

Reproduced the bug, will fix soon.

[luke-jr]

Please confirm that it is fixed in http://luke.dashjr.org/programs/bitcoin/files/bitcoind/misc/0.15.x/tmp-942fcf8e60/

[nikitasius]

Looks fixed!

Before: https://github.com/bitcoinknots/bitcoin/issues/8#issuecomment-332626483

Now:

and here are settings:

I will let it download all. Great job. Finally i will be able to use bitcoin API <3

[nikitasius]

what finally you did? And why debian was affected?

[luke-jr]

Had to reorganize the code a bit. It was trying to set the prune value before it determined the datadir. So I made it wait to write it until later.

[luke-jr]

Final fix will be released in 0.15.1. Until then, the custom build is needed for the first-time run only - once it's set correctly, you can use the normal 0.15.0 release.
