Fedora Devs,
I just spent the last couple of days fighting with Essex on RHEL6 and its been
entertaining and I'd like to share some of the oddities and experiences.
System configuration is the following.
Two nodes on their own /24 connected by cross over to each other on the second interface.
The first node is the cloud controller and has tons of storage (11T) and 32Gb ram and 16
cores
The second node I would like to make an extra compute node and it has 24Gb ram and 8 cores
(still in a work in progress)
Originally the cloud controller was running Diablo on RHEL6 and was working fine.
I couldn't find any 'upgrade' instructions for going between Diablo and Essex
and I wasn't too worried because the usage of the cloud was limited to just a couple
of guys. So I was satisfied with backing up manually all the data and rebuild the cluster.
I noticed when I did the update that things stopped working and following the install
instructions blew away all local data in the cloud.
I was following the instructions found at the following URL.
http://fedoraproject.org/wiki/Getting_started_with_OpenStack_EPEL
I got the packages from
http://pbrady.fedorapeople.org/openstack-el6/
First issue. Wow, this is long, its almost long enough that making an uber script in a
common package somewhere to run would strip out of most of the manual commands to run.
I'd suggest first pulling out all the openstack-config-set commands and put them in a
script to run. Not sure what to do about the swift documentation bits, that seems like a
very manual set of configurations why aren't they part of the swift rpm? Another
suggestion would be to split it out into a couple of documents one describing installation
and configuration then the next describing putting data/users into it and starting stuff?
thoughts?
After I got everything setup and working I noticed an issue with the dashboard, most of
the static stuff wasn't showing up I had to add a symlink.
/usr/share/openstack-dashboard/static -> openstack_dashboard/static
Then the dashboard picked up the right stuff and it worked.
There's some consistency issues and I'm not sure if this is an openstack issue in
general. The euca tools and how you configure them with keystone only seem to work with
your personal instances and configuration. However, the dashboard seems to show users
everything associated with the project instead. For example when I allocate floating IPs
from the website those won't show up when I run euca-describe-addresses and
respectively euca-allocate-address won't show up the IP allocated in the dashboard.
I've looked at the database and the project ids are used when using the dashboard and
user ids are used when using the euca tools. I think the euca tools could be setup to see
everything that the dashboard sees however the documentation doesn't point to how to
do that.
There also seems to be some serious functionality faults that I can't seem to make
work. I can't make a user attached to multiple projects, not sure how to do that.
Also, seems like there's a lot of, "huh, that doesn't seem implemented
yet." However, this seems like a general openstack issue, documentation says X but
that doesn't work yet or anymore.
I'm having a serious issue not getting a the second compute node working `nova-manage
service list' doesn't show ':-)' for the compute and network services
running on that node. I've followed the instructions to the letter and tried getting
things working but its not going.
