> Not able to deploy Vm because of crossing pool.storage.allocate
> d.capacity.disablethreshold even though the threshold has not been reached in
> the primary store.
> Steps to reproduce the problem:
> Xenserver set up with 2 Xensserver hosts:
> In my case , Primary storage NFS has 222GB . (storage.overprovisioning.factor
> is set to 2).
> I tried to deploy 20 Vms with the same template that has Virtual size of
> 20.00 GB and actual size is about 10 GB.
> I was allowed to deploy only 17 Vms after which Vm deployment fails because
> of the following exception because of crossing pool.storage.allocate
> d.capacity.disablethreshold :
> 2014-01-06 17:34:21,881 DEBUG [c.c.s.StorageManagerImpl]
> (Job-Executor-32:ctx-2a944d7f ctx-6e9eaab0) Checking pool 1 for storage,

> threshold: 0.85

> ol[24|vm=24|ROOT]], maxSize : 475554381824, totalAllocatedSize :

> 2014-01-06 17:34:21,886 DEBUG [c.c.s.StorageManagerImpl]
> (Job-Executor-32:ctx-2a944d7f ctx-6e9eaab0) Insufficient un-allocated
> capacity on: 1
> for volume allocation: [Vol[24|vm=24|ROOT]] since its allocated percentage:
> 0.8745292421128761 has crossed the allocated pool.storage.allocate
> d.capacity.disablethreshold: 0.85, skipping this pool
> Since Xenserver uses thin provisioning , the base copy of the template in
> primary is 10 GB. All the vhd entries of the Vms are very small and point to
> the base copy. We need to allocate only 10 GB space ( 20 GB (virtual size of
> template) - 10 gb ( actual size of tenplate) for each of these Vms , in
> addition to 10 GB for the base template copy.
> But we are allocating 20 GB for each of the Vms deployed.
> Reported Primary Storage capacity - 82 % - 367.32 GB / 442.89 GB
