One Server crashing often / different hardware setup

Pelle,

   It is certianly possible that the different configuration in Node 3 is causing issues.  When you say the box crashes alot, are we talking about vertica on the box crashing, or the entire box?

Hey Chris,

thanks for your reply and sorry for being so unspecific. It's the vertica instance crashing, not the entire server.

Cheers

Pelle,

   Ok, in that case, what I would try first is limiting the number of cores in node 3 to match the number of cores in nodes 1 and 2.

Here is an article I found online that walks you through that - http://www.absolutelytech.com/2011/08/01/how-to-disable-cpu-cores-in-linux/ 

Typically we don't do a lot of testing on non-homogeneous configurations, so this will be interesting!

Thanks, I'll try that right now :-)

I'm hoping that no news is good news.  How did restricting the number of CPUs in node 3 work out?

-Chris

Hi Chris,

sorry for getting back so late... I found out that all three nodes had different CPUs so we deceided to replace the hardware with identical stuff. It seems to be stable since.

Thanks for your help :-)
