What is a "Local Limit" at rancher 1.2 host page?

In my case I saw at Storage section:
45.2 GiB
Local Limit: 41.5 MiB.

For me meaning of “Local Limit” and it size is unclear, and I didn’t found it at documentation.

I have issue with pods which stays in pending at kubernetes environment, probably “Local Limit” it might be something related to this, because other resources at cluster like cpu, mem mostly free, therefore I have to be sure what sense “Local Limit” has.

My nodes has capacity like this
“status”: {
“capacity”: {
alpha.kubernetes.io/nvidia-gpu”: “0”,
“cpu”: “1”,
“memory”: “4044772Ki”,
“pods”: “110”
