AWS EKS EFS mounted volume. In spite 21Gi in claimed volume the pod has 8E (full possible size of EF-CodePudding

In spite 21Gi being set in claimed volume, the pod has 8E (full possible size of EFS)

Is it OK and storage size is limited. Or did I make a mistake in configuration and there needs to change, or something other?

I will be appreciated for your help.

CodePudding user response：

The number "8E" serves as an indicator, it is not a real quota. AWS EFS does not support quota (eg. FATTR4_QUOTA_AVAIL_HARD). It generally means you have "unlimited" space on this mount. There's nothing wrong with your spec; the number specified in the PVC's resources.requests.storage is used to match PV's capacity.storage. It doesn't mean you can only write 21GB on the EFS mount.
