I think it is totally ludicrous (and to all the technical writers who work on OpenStack, downright offensive) to say the “docs are useless”. Not only have I been able to install and successfully operate a OpenStack installation by (largely) following the documentation, but “trove-integration” and “redstack” are useful for developers but I would highly doubt that a production deployment of Trove would use ‘redstack’.

 

Syed, maybe you need to download a guest image for Trove, or maybe there is something else amiss with your setup. Happy to catch up with you on IRC and help you with that. Optionally, email me and I’ll give you a hand.

 

Good job on getting all the core services installed and running, and welcome to the OpenStack community.

Hi,

 

I’m installing and configuring trove(DBaaS) for exisitng openstack setup.  

 

I have openstack setup and able to boot nova instances with following components:

1.       keystone

2.       glance

3.       neutron

4.       nova

5.       cinder

 

Followed below documentation for manual installation of trove:

http://docs.openstack.org/developer/trove/dev/manual_install.html  and few correction given in this mail thread https://www.mail-archive.com/openstack%40lists.openstack.org/msg05262.html .

 

Those docs are useless, since they are not reflecting significant step - creating custom Trove images. You need to create image with Trove installed in it, create upstart scriptto lauch Trove-guestagent with appropriate configuration files that comes to the compute instance through file injection.

Vanilla images are good, but they don't have Trove in it at all.

Here are some useful steps:

1. Create custom image with trove code in it (upstart scripts, etc).

2. Register datastore and associate given image with appropriate datastore/version.

FYI, Trove is not fully integrated with devstack, so, personally i'd suggest to use https://github.com/openstack/trove-integration  simple (3 clicks) Trove + DevStack deployment.

 

 

Booted up a trove instance

trove create myTrove 7 --size=2 --databases=db3 --datastore_version mysql-5.5 --datastore mysql --nic net-id=752554ef-800c-46d8-b991-361db6c58226

 

Trove instance got created but is STUCK IN BUILD state.

 



 

*         nova instance associated with db instance got created successfully.

Correct. 

*         Cinder volumes, security groups etc are also getting created successfully.

Correct. 

*         I checked nova, cinder logs everything looks fine but in trove-taskmanager.log below error got logged:

PollTimeOut: Polling request timed out

 

Correct since Trove-guest agent service wasn't able to  report about its state.

I am also unable to access mysql in the booted up trove instance . via : mysql –h <instance-IP>

*         Also I’m unable to delete this instance.

o    ERROR: Instance 23c8f4d5-4905-47d2-9992-13118dfa003f is not ready. (HTTP 422) (may be this is expected) 

Correct. You cannot modify/use instances that are remaining in BUILD state.
 

I’m a novice in Openstack but new to trove.

Thanks in advance and any help is greatly appreciaited.

                

Thanks & Regards,
