DNS and Resuming a Suspended VM

[Jay Farschman]

I ran into a problem this morning where resuming a suspended VM does not refresh the DNS zone.

I suspect I could use the "ResumeComplete" event trigger to kick DNS in some way, but I thought I should ask advice.

Does anyone have a way to handle this?  For us, I have told users to suspend their VMs at night and not to worry about the DNS.  It's handled, but it seems like DNS just disappears for suspended instances.

REPLICATE IT

1. Create a DNS Zone and point it at a Farm Role.
2. When you issue the suspend command DNS records are removed from the zone record even before the system is fully suspended.
3. Once the WebUI says the instance is suspended, it is not completely suspended, but in 20 seconds or so it reaches that state in AWS.
4. On resume Scalr will fire the "ResumeComplete", but this does not seem to refresh the DNS zone.

This is still a problem, and I'll entertain, even crazy ideas on how to solve it.  Sadly, I do not understand enough about how a Scalr Agent's "ResumeComplete" can be used on the Scalr Server.  I only understand how to make scripts run on the scalr agent instance.

Hey Jay!

Sorry for my late response. We will look into this and get back to you.

This issue has been fixed. Fix will be included in the upcoming Scalr CE release.

Vitaliy & Daniele,

Thanks for this. I appreciate it.  Just wish I could patch it myself.  I will put those ideas aside and say thanks.
