when deploy POD in k8s, user set 
request
and 
limited
, the 
request
will be treated as 
reserved
.
and 
used
is the actual running statistics
you can change them by set the params of 
deployment
, if there are parent objects of 
deployment
, you need to set until the root object
What do you mean 
what is the meaning of Storage Scheduled
?

Thank you for your response, @ancient-pizza-13099. Regarding the storage scheduled, I am encountering an error on one of our servers having sufficient storage space. Could you please explain why this might be happening?

FYI, this KB reveals how resource usage is calculated. https://github.com/harvester/harvesterhci.io/pull/52
@loud-summer-33688 :

Im reading about the amount of replicas in storage class, do you know how can I change the amount of replicas ? from 3 to 3, for example
a
You need to create a new 
storage-class
(select replica 1), and set this one as the default.

Your issue is: why there is 727 G scheduled? it means you have already create some VMs with big disk, and the overall scheduled is over the https://longhorn.io/docs/archives/1.2.6/best-practices/#minimal-available-storage-and-over-provisioning
Your host have only about 439G disk available; and already scheduled with 727G , the default over-provision is 200%

LH complains that it cann't schedule more
the below code is hit:
Copy code
func (rcs *ReplicaScheduler) IsSchedulableToDisk(size int64, requiredStorage int64, info *DiskSchedulingInfo) bool {
	// StorageReserved = the space is already used by 3rd party + the space will be used by 3rd party.
	// StorageAvailable = the space can be used by 3rd party or Longhorn system.
	// There is no (direct) relationship between StorageReserved and StorageAvailable.
	return info.StorageMaximum > 0 && info.StorageAvailable > 0 &&
		info.StorageAvailable-requiredStorage > int64(float64(info.StorageMaximum)*float64(info.MinimalAvailablePercentage)/100) &&
		(size+info.StorageScheduled) <= int64(float64(info.StorageMaximum-info.StorageReserved)*float64(info.OverProvisioningPercentage)/100)
}
