Hi Folks,
We are facing an issue where on EKS when we have multiple NVME drives mounted to /var/lib/docker and /var/lib/kubelet the kubectl describe only shows size of root storage and not the over all size. Before bootstrap.sh along with cloud-init we add all non root disk devices to a single volume group and then create logical volume. After this the directories mentioned above are mounted to it. Disks can be upto 3.4 TB in size.
We add 1-4 sometimes more disks.
Is this related to this mentioned issue?
Note:
The kubelet will only track the root filesystem for ephemeral storage. OS layouts that mount a separate disk to /var/lib/kubelet or /var/lib/containers will not report ephemeral storage correctly.
I believe it to be similar to this issue Incorrect ephemeral capacity detected by kubelet when using large EBS volumes · Issue #647 · awslabs/amazon-eks-ami · GitHub.
Any help is appreciated thanks.
