It is not related to RAM or CPU. I run installation on my Mac with 1Gb of
RAM for master node, and experience the following:
- yes, it needs time to bootstrap admin node
- As soon as I have message that master node is installed, I immediately
open 10.20.0.2:8000 and try to generate diag snapshot. And it is failed.
- If I wait a few more minutes, and try again - it is passed.
It actually seems to me that we simply still do not have
https://bugs.launchpad.net/fuel/+bug/1315865 fixed, I'll add more details
there as well as logs.
When I checked logs, I saw:
- for about a minute, astute was not able to connect to MQ. It means it
is still started before MQ is ready?
- shotgun -c /tmp/dump_config >> /var/log/dump.log 2>&1 && cat
/var/www/nailgun/dump/last returned 1
When I tried to run diag_snapshot for a second time, the command above
succeeded with 0 return code.
So it obviously needs further debugging and in my opinion even if we need
to increase VCPU or RAM, then no more than 2 VCPU / 2 Gb.
Vladimir, as you and Matt were changing the code which should run
containers in a certain order, I'm looking forward to hear from both of you
suggestions on where and how we should hack it.
Thanks,
