catch panic err="mkdir /data: file exists"

[bbista100]

Please help! I run "systemctl start supervisor" and I get this in the logs:

[EROR] [04-28|00:08:53.529] catch panic err="mkdir /data: file exists" stack="[main.go:22 panic.go:1038 flags.go:749 flags.go:573 flags.go:841 flags.go:889 node.go:79 main.go:37 app.go:526 app.go:286 main.go:27 proc.go:255 asm_amd64.s:1581]"

/data is the file? Not a directory?

[AskAlexSharov]

ls -la /data

[AskAlexSharov]

"systemctl start supervisor" - then show your erigon.service file

[AskAlexSharov]

OS? FS?

[bbista100]

Hi again. Ubuntu 22.04 LTS with Ext4 filesystem. The erigon.service files don't get created at all, I'm looking in /etc/systemd/system.

[bbista100]

Here is my /etc/supervisor/conf.d/erigon.conf file

[program:erigon]
command=bash -c '/opt/erigon/bin/erigon --datadir="/data/erigon/datadir" --private.api.addr="0.0.0.0:9090"'
user=erigon
autostart=true
autorestart=true
stderr_logfile=/var/log/supervisor/erigon.err.log
stderr_logfile_maxbytes=1000000
stderr_logfile_backups=10
stdout_logfile=/var/log/supervisor/erigon.out.log
stdout_logfile_maxbytes=1000000
stdout_logfile_backups=10
stopwaitsecs=300

[bbista100]

And my /etc/supervisor/conf.d/rpcdaemon.conf file:

[program:rpcdaemon]
command=bash -c '/opt/erigon/bin/rpcdaemon --datadir="/data/erigon/datadir" --private.api.addr="localhost:9090" --http.addr="0.0.0.0" --http.port=8545 --http.vhosts="" --http.corsdomain="" --http.api="eth,debug,net,trace,web3,erigon" --ws'
user=erigon
autostart=true
autorestart=true
stderr_logfile=/var/log/supervisor/rpcdaemon.err.log
stderr_logfile_maxbytes=1000000
stderr_logfile_backups=10
stdout_logfile=/var/log/supervisor/rpcdaemon.out.log
stdout_logfile_maxbytes=1000000
stdout_logfile_backups=10

[bbista100]

And I've set this data directory for Erigon to work with: /data/erigon/datadir

[AskAlexSharov]

can you try to run without supervisord:
/opt/erigon/bin/erigon --datadir=/data/erigon/datadir
and show here the output

[AskAlexSharov]

FYI: now RPCDaemon can work inside Erigon. All that flags --http.addr="0.0.0.0" --http.port=8545 --http.vhosts="" --http.corsdomain="" --http.api="eth,debug,net,trace,web3,erigon" --ws are now available in Erigon also.

Thanks Alex!

[bbista100]

So it works like this, right?

Now how do I change /etc/supervisor/conf.d/erigon.conf and /etc/supervisor/conf.d/rpcdaemon.conf so "systemctl start supervisor" works too?

[AskAlexSharov]

yes, it works. supervisord - i don't know. read logs and docs of that systems.

[bbista100]

Thanks very much!
