Hi,

bit follow up. when i’m trying “makeconfluent -l” on local running instance i 
see error:

Yeah, there will be a bit push in the coming weeks it will have at least an 
‘events’ log along with a lot more function.

 

Then some more fleshed out documentation (beyond the preliminary stuff on 
hpc.lenovo.com).

 

Let me know if the firmware exploration works out.  That particular change line 
suggests firmware upgrades, but it is possible they could have some high BMC 
cpu usage that could manifest in such a way.  The ‘works with ipmitool’ though 
has me scratching my head.

Last idea doesn’t work for me. So by the way idea as is is working great – 
confluent does disconnect/connect after time in constant. But for now it is 
100% correct to say  – it is a problem with IDRAC fw.

from release notes for last fw:

===

- Fix for occasional iDRAC unresponsiveness caused by upgrades via Firmware 
RACADM or
have an active SOL or SSH sessions while firmware upgrade is in progress.

===

I’m not sure, but maybe its something like i have here. So did the upgrade on 
few hosts and give them plenty of time to show me results.

Thanks for your answers, help and time… it is very interesting quest :)

 

Bit more about Confluent:

- Interesting ambitions 

- Python VS Perl, thats good

- I think log files(not just trace, stderr, stdout) and documentation(source on 
Github is the best doc o know, but…) are things that i would like to be in 
Confluent

I’m loathe to do a workaround, but in console.py (find /usr –name console.py) ,

If it would pan out, should cause the console session to disconnect itself 
roughly every 90 minutes and trigger reconnect (is 90 minutes short enough in 
your case?)  Would require a service confluent restart to see if it had the 
desired effect.

 

Sorry I haven’t tested and can’t think of root cause, but going to take some 
time off for the weekend.

 

I would be curious if the same ipmitool is running a day later than a check 
(e.g. if ipmitool is exiting and getting restarted).  I don’t have the time at 
the moment to see if they do some other interesting thing to avoid the behavior.

Yes, reopen causes it to work again,  without any garbage… so looks like normal

Console starts showing garbage after <enter> inside rcons.

What do you mean when said “restarting console”?

Console continue its work after:

- <enter> inside rcons/confetty

- bmc reset (console disconnected/console connected)

 

You’re absolutely right with ipmitool and conserver with the same servers we 
were out of such troubles.

Pyghmi will do keepalive as well, and if that’s the problem, it should be much 
shorter than 24 hours.  In fact, it should be checking if the SOL payload is 
active and owned by confluent specifically every couple of minutes.

yes, thats correct

My last reply was incorrect. Problems still here. Im trying to find something 
usefull inbetween confluent/pyghmi...

Confluent restart solves hangs/reopen all connections.

I think it isnt the best option to restart confluent 1 or 2 times in 24h.

behaviour.

Some of my consoles hangs ~after 24, so no any new messages in their logs or in 
rcons.

I send messages with timestamp from OS >/dev/console every 30-60min and take a 
look on them for monitoring purposes(consoles availability monitoring).

I can open rcons and hit enter, after few secs console is waking up(strange). I 
didnt see it happen with conserver or maybe im wrong...

Some details:

- as i can see the bigest part of consoles with hangs behaviour are Dell idrac. 
Doesnt matter which type of RacSerial or IPMISerial is in use.

- racreset hard/ipmitool bmc reset didnt do the things

- hit enter to console wake it up(for example with expect i can send \r\n\f, 
but it looks bad)

- i didnt try to clean confluent's conf and restart it. Not sure it may help.

- HP consoles works well, same ipmi

- few consoles with custom pluging works good as well

 

So maybe my question is not about confluent, but if some of you have some 
knowledge about same problems please share it! ;)
