Thor Slave won't start

[lpezet]

Hello!

I've been trying to install new version of HPCCSystems Platform on Ubuntu 20.x but I'm facing an issue where the Thor Slave just won't start.
I tried HPCCSystems Platform 8.2, 8.0 and 7.12 (latest for each) on Ubuntu 20.04 and 20.10 but I get the same behavior.
Every time I simply do:

Code: Select all

dpkg -i hpccsystems-platform....
apt install -f
systemctl start hpccsystems-platform.service


When I run preflight certification, it shows Thor Slave is not ready.
Doing simple ps auxwww | grep hpcc I get the following:

(had to remove some lines from it to be able to submit this post).

I can run manually the ssh command from above, or even directly the thorslaves-exec.sh (with all the right values) but nothing shows up (no errors, no output). I ran the command that thorslaves-exec.sh runs, systemctl start [email protected]thorslave_mythor_1.service, and here is its status:

Code: Select all

Any idea why the slave would not start? Any idea how I could get more logs here to understand what's going on?

Thanks!

I've now gone down all the way to HPCCSystems 7.8 on Ubuntu 20.04 and still getting the same behavior WHEN USING systemctl (as mentioned in the doc: https://cdn.hpccsystems.com/releases/CE ... .2.2-1.pdf).
Now I went back to HPCCSystems 8.2/Ubuntu 20.04, but this time using the old school /etc/init.d/hpcc-init start and it worked!
Here are the processes I get for hpcc user:

Preflight/certification is all good to.
Why, oh why?

[mgardner]

Ipezet, thanks for bringing this up. I've opened a Jira ticket and I'll be investigating the issue. https://track.hpccsystems.com/browse/HPCC-26258

Reading the info you provided, it looks like there isn't actually an issue with the ssh call going through, the error is in the thorslaves-exec.sh script?

[lpezet]

Hello!

I would say thorslaves-exec.sh runs fine, and it's something with /opt/HPCCSystems/bin/thorslave_lcr. When I try to run manually /opt/HPCCSystems/bin/thorslave_lcr I can't get much from it (besides its usage if I don't pass the right parameters): exit code is always 0 and no std/error output.

[lpezet]

Could I get access to that JIRA ticket?
https://track.hpccsystems.com/browse/HPCC-26258

I'm at it again trying to run version 8.4 on Ubuntu 20.04 LTS and I'm still having issues with that new "systemctl" way of things. I'd like to check on that ticket if there's anything I could try to make it work.

Thanks!

lpezet,

You should be able to simply click on that link and get to the ticket. JIRA will ask you to login, so if you do not yet have a JIRA account you can just sign up to get one. Remember, this is Open Source so the JIRA tickets are visible to everybody.

HTH,

Richard
