Sync Stuck - Bitcoin Core (linux)

[simon04]

So basically, I downloaded "Bitcoin Core" on Linux Mint and bought some Bitcoins...

Then I started the sync, but it is stuck at 7 days, with a zero balance shown.


I'd be grateful for some help to fix this, in a way that I don't lose my balance...


Thanks for your suggestions.

your balance is safe, it will be displayed when the your client will be fully synched

the synching of the whole blockchain require a great amount of time(depend on your hdd/ssd), how many hours since you started synching?

Have been running for 2.5 days.... now stuck on a certain block at 7 weeks....

then something is wrong in your roaming, usually this is the case, check also how many connections do you have in your client

I was looking at 21 connections earlier... yesterday around 14

What version are you running? 0.10.0? (Or 0.10.1?)

[simon04]

What version are you running? 0.10.0? (Or 0.10.1?)

It is v0.10.0

[simon04]

Now that you said it... I have downloaded 10.0.1 instead.

[cr1776]

What version are you running? 0.10.0? (Or 0.10.1?)

It is v0.10.0

You might give 0.10.1 a try.

You might give 0.10.1 a try.

Thanks, I'm currently testing that.......

Is downloading the bootstrap.dat an option? (If the new version of Bitcoin Core not solve the problem?).

0.10.x should be faster syncing than using the bootstrap option. 

Are you running on a SSD or HDD?  (You might have to restart it IF there was corruption in the download before.  If you are using an SSD, it should not take long, you can always add specific nodes to connect to - Shorena has a list of fast nodes if that becomes needed).

You summoned me? You can force bitcoin core to connect to a specific node and no others if you think the nodes you are connecting to are not providing all the bandwith/blocks they should.

Start bitcoin core with -connect=IP

AFAIK IP can be a list of IPs seperated with "," e.g.

Code:

-connect=185.45.192.129,94.23.146.127,213.165.91.169,191.236.50.217

that should make sure you are connected to a well connected node with the latest blocks, once you are fully synced run as usual.

Thanks, looks like good info.

Sadly, I already downloaded bootstrap.dat and tried loadblock....

How long should this take? There is no indication of progress..

Somewhere between 30 minutes and a couple of hours. From the bootstrap.dat it mainly depends on diskspeed unless you have a very slow CPU.

With SSD being much faster than a HDD.

Thanks for all the replies.

The data somehow was corrupted, so I sent the bitcoins to an online account.

I will have a go at the software another time.....
