[BUG] My Raspberry Pi 4 4GB currently misses / doesn't finish plenty of signage points in a row

Describe the bug There seem to be phases when my Raspberry Pi 4 GB farmer is missing several signage points in a row. As a consequence, the farmer is not participating these challenges.

E.g. around height 113661:

Missed signage points 38 until 59, inclusive. That’s 22 uninished signage points in a row.

I have already limited the number of target_peer_count to 30, guessing my Raspi may be overloaded during some p2p network bursts, but this did not resolve the issue.

I have added logging statements to find out under which conditions signage points don’t get added. A failing signage point always seems to happen when verify_n_wesolowski doesn’t manage to return True eventually, i.e., all wesolowski tries for this signage point return False.

Expected behavior All signage points shall finish.

• OS: Ubuntu Server 20 LTS
• Machine: Raspberry Pi 4 4 GB

It seems I have found a solution to this issue for my setup.

My current theory for this issue is that there is too much filesystem IO going on on the Raspberry Pi’s SD card when Chia’s config directory ~/.chia is located on the SD card. After all, not only OS-related IO is going on on the SD card, but any Chia-related filesystem IO such as SQLite database IO and Chia logging. SD Card-based ~/.chia is set up when following the current Raspberry Pi Chia installation documentation, therefore I expect many if not all Raspberry Pi Chia users facing this problem with “normal” Raspberry Pi-recommended SD cards.

To bring this issue theory to test by resolving the issue, I changed Chia’s config directory ~/.chia from SD card to a separate (and fast) USB 3.1 flash drive (thumb drive):

cd chia-blockchain

# stop Chia processes and daemon, e.g. by running
chia stop -d all

deactivate

# assuming a ext4-formatted, fast thumb drive mounted on /media/thumb
cp -r ~/.chia /media/thumb
# this will take a while, copying gigabytes of log and sqlite databases. You can monitor progress in a separate shell with `watch progress`

# we now have a copy of our Chia configuration on the external thumb drive located at /media/thumb/.chia
# now let's move the SDCard-hosted Chia config directory to another location on the SDCard
mv ~/.chia ~/.chia-backup

# ~/.chia is now available for setting up a symlink to the USB Drive-hosted Chia config directory.
# Let's set up this symlink:
ln -s /media/thumb/.chia ~/.chia

# start up Chia again

. ./activate

# use your usual way of starting up, e.g.
chia start -r node wallet harvester farmer

Monitor your logs. If everything goes well like it did for me, all signage points should now finish correctly:

$ tail -F ~/.chia/mainnet/log/debug.log  | grep -i -e 'finished signage point' -e 'finished sub slot'

From 1 to 64, all signage points within a sub slot now finish.

I have been using this solution for four hours now and so far haven’t missed finishing a single signage point. In two days, I will be able to report back full-day statistics.

In case this solution (i.e., moving ~/.chia onto a separate device) turns out to be a viable solution, and other Raspberry Pi users facing this issue can resolve it by following this solution as well, I recommend updating the Raspberry Pi Chia installation documentation accordingly.

P.S.: In case you added an additional external drive because of this and this solution works well for you, in all euphoria don’t forget to mount this new drive on boot by adding a new entry to /etc/fstab.

P.P.S.: When things have worked well for some time, it will be save to free space on the SD card by deleting ~/.chia-backup, though it’s always nice to have some backup of your SQLite databases around in case the live versions get corrupted for some reason.

What do I need to check in the logs to see this on my pi4

@grocheireland:

• Set logging level on INFO
• Print out and filter live logging with the following shell command:

tail -F ~/.chia/mainnet/log/debug.log | grep -i -e "eligible" -e "updated peak" -e "signage point" -e "end of slot" -e "updated wallet peak" -e "sub slot"

If logging looks similar to this …:
