Subject AW: Deployment failed on XenServer due to capacity miscalculation
Date Wed, 08 Jul 2015 11:45:18 GMT

The config options are on their default value:

mem.overprovisioning.factor = 1
cluster.memory.allocated.capacity.disablethreshold = 0.85 (Would affect the whole cluster
capacity, not that of a single host)

So nothing strange here.

I un- and remanaged the cluster, but no change in numbers :(
Also there were no interesting log messages...

Hi Martin,

I have seen this before with our CXS environment too.

Could of things to check:

1. What is the mem.overprovisioning.factor field set to?
2. What is the cluster.memory.allocated.capacity.disablethreshold field set to?

Also, try unmanage the XS Cluster, wait a couple of minutes and re-manage it.

I tried that ("force reconnect"). But no improvement:

Via cloudmonkey, memorytotal-memoryallocated == 4302535168, that's 4103MB. Via XenServer,
the host has only 1667 MB free memory.

Restarting the management server does not solve it, either. I see this:

2015-07-08 12:03:40,612 DEBUG [c.c.c.CapacityManagerImpl] (CapacityChecker:ctx-6c463573) Found

My current "workaround" is to disable the host in ACS, then the deployment planner takes the
other host with enough free memory, but that's not a permanent solution.
