Here is an issue with aws-ebs-csi-driver: The size of file system doesn’t change when pvc is expanded. I got the same issue when I tried to do the Curl elk in pods to delete indices this afternoon. I got the message "resize2fs 1.44.5 (15-Dec-2018) open: No such file or directory while opening /dev/nvme1n1" as well when I tried to resize the file system /dev/nvme1n1 in my pod. As the issue is about csidriver, it is not in the the result of running command "kubectl get csidriver" on my cluster.

As in my previous article, I gave the following information of my pod. I still have some time before bed, I couldn’t help to seek the reason of that. /usr/share/nginx/html # df -h Filesystem Size Used Available Use% Mounted on overlay 80.0G 34.5G 45.5G 43% / tmpfs 64.0M 0 64.0M 0% /dev tmpfs 3.7G 0 3.7G 0% /sys/fs/cgroup /dev/nvme0n1p1 80.0G 34.5G 45.5G 43% /dev/termination-log /dev/nvme0n1p1 80.0G 34.5G 45.5G 43% /etc/resolv.
