EXT4-fs (dm-3): Couldn't mount because of unsupported optional features (2000)

What steps did you take and what happened:
pvcreate /dev/sdc
vgcreate lvmvg /dev/sdc

1.StorageClass, pv and pvc is ready , but the pod is in ContainerCreating.
2.dmesg -T: shows "EXT4-fs (dm-3): Couldn't mount because of unsupported optional features (2000)"

kd pod {podid}:

Environment:

• LVM Driver version : kubectl apply -f https://openebs.github.io/charts/lvm-operator.yaml
• Kubernetes version (use kubectl version): 1.23
• Cloud provider or hardware configuration: linux kernel 3.10.0
• OS (e.g. from /etc/os-release): redhat7.6

wonder if it is caused by the kernel not supporting ? Thank u

this tip is true！

Seems your kernel does not support the features being used.
But yes, installation via operator is not the supported way indeed.
