[Swift-user] Coaster Service Startup Time on OSDC

[Matthew Shaxted]

Sure thing David,

I have a setup.sh script that exports WORKER_HOSTS IP addresses from a txt file (see attached) - all nodes are running centOS.

The conf file I am using is also attached. I'm using swift-0.94.1.

Many thanks,
Matthew

Hi Matthew,

Could you please explain a little more about how you're starting the coaster-service and workers? Are you using the start-coaster-service script? If you are, could you please send the coaster-service.conf file you're using? Which version of Swift is this?

There may be some things we can do to speed up the process - just need to get a better understanding of how things are set up and where the delays are coming from. Thanks!

Regards,
David

Dear Swift User Group:

I working with a 60-node cluster running on OSDC now, and when I try to start the Swift coaster-service for these nodes, it takes about 30 seconds (or more) per node to successfully start.

This is an issue for me as it limits how often I want to shut down the coaster-service - for this 60 node cluster it could take up to 30 min to start up again.

Is this starting coaster behavior normal? Is there anything I can do to make the coaster-service start faster?

Thanks,
Matthew
