[rdo-dev] tripleo cluster failure

[Rahul Pathak]

Reminder!! Please help. 
------------------------------- 
Hi, 

Is there some kind of script that I can run to know the exact issue about what resource crunch is there ? 

Below is the memory and disk utilization of controller: 

[heat-admin at overcloud-controller-0 ~]$ free -m 
total used free shared buff/cache available 
Mem: 128722 25632 92042 70 11047 102377 
Swap: 0 0 0 
[heat-admin at overcloud-controller-0 ~]$ df -h 
Filesystem Size Used Avail Use% Mounted on 
devtmpfs 63G 0 63G 0% /dev 
tmpfs 63G 39M 63G 1% /dev/shm 
tmpfs 63G 27M 63G 1% /run 
tmpfs 63G 0 63G 0% /sys/fs/cgroup 
/dev/sda2 1.9T 12G 1.9T 1% / 
tmpfs 13G 0 13G 0% /run/user/0 
tmpfs 13G 0 13G 0% /run/user/1000 

Same memory and disk available on all three controllers. 

On the same environment when I installed overcloud with redhat repos and redhat overcloud images...I have not faced this issue. I have tested almost 500 projects and 500 networks (one network per project) on the same environment with redhat and it was working fine without any issue and cluster failure. But when I am using Centos-7 tripleo repo's its happening again n again.

Hi all! 

Rahul - there is nothing relevant in the attached file, you've probably executed LogTool on "working environment", so there is nothing interesting in it. 
I think that you had to mention the Error we've detected in an already "crushed" environment, just as I was suggesting you to do. 




Yes, nothing interesting in the attached logs.

Alfredo - this Error was logged almost on each OC node at the same time when the problems had started.

I'd suggest to check rabbitmq and mariadb logs. 

AFAIK, there is not a configuration that may limit the number of networks or project, but it may be hitting some resources scarcity that affect the running services. What's the memory sizing and usage of the controllers?

You can find more Error Blocks in the attached file. 

Thanks!
