Hi,
I've ran into the issue where it seems that local storage can't be
overprovisioned.
storage.overprovisioning.factor is set to 1.5 in both the global and
zone settings, but this is ignored.
In this case it's a 1TB SSD which currently has 68GB allocated on
disk, but 750GB of disk space has been allocated according to CloudStack.
Looking StorageManagerImpl there is this if-statement:
if (storagePool.getPoolType() == StoragePoolType.NetworkFilesystem ||
storagePool.getPoolType() == StoragePoolType.VMFS) {
DO OVERPROVISION
} else {
DO NOT OVERPROVISION
}
So why is local storage excluded here? Since QCOW2 is sparsely
allocated and templates deployments are just clones of a parent QCOW2
it's fair to say that with local storage you can also overprovision?
Any objections to adding this?
Wido
