today my node at home with an old RPI 3 was offline after running about 1 month without problem
after reboot i noticed:
syslog:
Nov 4 00:20:46 raspberrypi kernel: [12930.050559] INFO: task storagenode:1647 blocked for more than 120 seconds.
storagenode:
2022-11-04T03:44:39.603Z ERROR piecestore failed to add bandwidth usage {"Process": "storagenode", "error": "bandwidthdb: database is locked", "errorVerbose": "bandwidthdb: database is locked\n\tstorj.io/storj/storagenode/storagenodedb.(
load average: was going crazy like 50 or even 90
after about 2 hours it was not responding anymore, only ping but SSH was not working and the xch (chia) miner was shown offline too
now the easy fix for me was limit the iops docker can use on the USB HDD with this:
root@raspberrypi:~# df -h

my node data is in /dev/sde1
remove old storagenode and add this to the docker command: --device-write-iops /dev/sde:300 --device-read-iops /dev/sde:300
my full docker command looks like this:
docker run -d --restart unless-stopped --stop-timeout 300 --device-write-iops /dev/sde:300 --device-read-iops /dev/sde:300 -p 28967:28967/tcp -p 28967:28967/udp -p 127.0.0.1:14002:14002 -e WALLET="mywallet" -e EMAIL="mymail" -e ADDRESS="myip:28967" -e STORAGE="4TB" --user $(id -u):$(id -g) --mount type=bind,source="/root/.local/share/storj/identity",destination=/app/identity --mount type=bind,source="/store/real",destination=/app/config --name storagenode storjlabs/storagenode:latest
HDD usage is down to 60-80% (from 100% all time)
load average: 4.82, 4.30, 4.23 (was 50 or more sometimes)
guess it will help the HDD to not die too fast, cant be good at 100% all time i think
its a 5TB 2.5" HDD, guess with a faster 3.5" u can use more than 300 iops
i will see some days if this works fine but looks very good now compared to before
useing clonezilla
