Message 1840006 - Posted: 4 Jan 2017, 23:01:14 UTC

So I upgraded one of my hosts operating system and changed the hostname...

Is there a way to manually force a merge of that host? I tried using the merge feature but I didn't get that option...

You could try changing your host name back to what it was and see if it gives you the merge option then.

Yeah, I'm trying to avoid that :/

Not permanently, just to get it to stnc with the new OS, then move it back again.

Hmm, great idea, let me try that...

I guess it's the differing processor count - How did that happen?

"So I upgraded one of my hosts operating system"

I'm not sure how fine-grained the back-end is on OS version changes, but this is almost certainly the cause of it not allowing the merge.

That's a lot more changing than just the OS - number of cores changed, name changed, memory changed, OS changed ... No wonder it won't merge!

I don't know if it's possible to edit the computer ID in cc_config, client_state, and other files to get it to merge or not.

Do you run any work on the host itself as well, or only via the VM?

I run other VMs...it's on a 3 node ESXi cluster.

It's a VM

There is a cc_config.xml option to override the number of processors BOINC thinks the system has.
You could try setting that to 6, setting the host name to match the old system, updating, and then see if it will allow a merge.
If that doesn't do it then plan B would be to set the new host to the old host ID. Which is actually a bit of a PITA. Backing up the data folder and dumping it on the new host of the easiest way to keep the old host ID without merging or stabbing BOINC with a stick.

Yeah, that cc_config.xml ting never worked :/

Again, it's really no big deal...
