Hi guys

I've got next error: Missing file for cnc: /dev/shm/aeron-deploy/cnc What should be in the file?

It should be created by the Aeron media driver

If you're using an external media driver in prod, you may not have started it yet

hm

hah, it was started by root

so name is aeron-root

fixing, thanks

Ah no wonder

lucasbradstreet: hm, weird

Don't see the directory aeron-deploy, but on another instance it's working good

Could you advice?

I'm running both services by the same way

But one working and another nope 😞

09:44:15.898 [main] INFO  c.highstorm.aeron-media-driver - Launched the Media Driver. Blocking forever...

Hm. first time I've started the driver manually, and after that it works

But I'm using same command in my upstart script and it doesn't work

lucasbradstreet: please let me know once you will be free, Wanna to investigate this

Hi @lowl4tency

Hi Lucas

I've fixed the issue, but still don't understand why I can't run it first time with upstart

Sent my upstart config to PM

While I don't start it manually (copy the line with "su - bla bla" and paste to termianl) it doesn't work

I've tried create the dir /dev/shm/aeron-deploy manually, but once I've start the driver it was deleted

At the moment it's not urgent and not critical, but when we start external aeron for prod it will be very important

Odd. Sorry, I’m not much help, I’m not seasoned in upstart

But it is almost definitely to do with the uid that the processes are started under

Okay I need a brake, all day fighting with the cluster

Will try later, I suspect it's permission issue
