Hello everyone,

How are you dealing with all your vms in a node doing tally at the same time? I?m sure you're getting very high i/o and wait, and probably vms even crashing.

Any have a decent solution for this except for scattering vm cron times?

Thanks
 
I'm presuming you mean what I call Xen. If so, then...

My understanding is that when using Xen you get the amount of resources you ask for, no more and no less. So perhaps each Virtual server needs to have more resources.

Try staggering the time on one of the servers to see if it helps that one run faster.

Well the resource you talking about are memory and space. those are definetely guaranteed. The problem is i/o

When you get all of them doing tally at the same time, your wait time skyrockets.

But yes, the only solution I can think of is mixing up tally times, but that's a pain in the arse for 40 vms,. in 7 nodes (over 250 vms).

Just wondering if any one else had a better idea.
