That's odd, this ought not to cause a failure. Try running with --log-level 4 (warning: very spammy), it's likely that there will be more logs after this, and the cause of the failure is unrelated to this large page message.
Thank you, going to try.
Also, check dmesg, it might just be the OOM killer.
The process doesn't die by the way, it keeps logging the error. It even seem to continue downloading but at much lower speed. I have restarted the download, I'll enable lvl 4 logging when it reaches 95% and see.
Ah, good. The slowness is because it start PoW checks, which it could skip for most of the chain. This can be closed I think, if it's working on your end ?
It failed again, but found the reason. I found in syslog that my SSD drive is disconnecting and reconnecting occasionally. It is attached to the RPi by a SSD HAT but maybe the monerod process is too intensive for it. I'll close this issue as not related to monerod. Thanks again for the suggestions.
I am using Ubuntu Core 20.10 on a Raspberry Pi 4 with 4GB of RAM. I have mounted an SSD (via USB 3) on
/opt
and themonero
I have built from sources following the README, using these settings:Then I am running the
monerod
using this command as a systemd service:I have also tried simpler commands without the
--enforce-dns-checkpointing --db-sync-mode=safe:sync --prep-blocks-threads 2
part. I have also enabled in/etc/dphys-swapfile
:I have tried with more swap as well.
The download process goes well and after about 30 hours, I'm getting around 96% (sometimes 97%) and then it starts failing with this error (I have removed
2020-12-11 05:39:06.496 [P2P7] INFO stacktrace
beginning of each line for readability)Seeing the first error being around large pages memory, I tried to see what I can do about it, but couldn't. I've seen something around some huge page configuration in
sysctl
but I don't find any in my Ubuntu config. I have followed the https://github.com/peanutsformonkeys/raspberry-monerod/blob/master/README.md and now trying to sync again after adding theswapiness
to 0. I doubt it would do but hey, I'll try all recommended settings.Anything else I can do? What can I do to not have this large page limitation?
