Not able to use instance created with aws bottlerocket image for local storage

[mdfaizsiddiqui]

Hi

I am trying to use instance created with bottlerocket image for local storage, but I see this error on helper pod -

Events:
  Type     Reason       Age                 From     Message
  ----     ------       ----                ----     -------
  Warning  FailedMount  53s (x8 over 116s)  kubelet  MountVolume.SetUp failed for volume "data" : mkdir /.bottlerocket: read-only file system

My helm chart values configuration for rancher local-path-provisioner -

storageClass:
          name: "local-storage-disk-rancher"
nodePathMap:
  - node: DEFAULT_PATH_FOR_NON_LISTED_NODES
    paths:
      - /.bottlerocket/rootfs/mnt/ephemeral

Can I know why it is trying to create a directory /.bottlerocket, ? I specified the path /.bottlerocket/rootfs/mnt/ephemeral not /.bottlerocket and i also ensured that path exists on the node (with a custom script that creates it) -

df -Th | grep mnt
/.bottlerocket/rootfs/dev/nvme2n1 xfs        55G  425M   55G   1% /.bottlerocket/rootfs/mnt/ephemeral

This is my bottlerocket setting (Note: I'm using karpenter to create these instances) -

[settings.bootstrap-containers.setup-ephemeral-disks]
    source = "registry.hub.docker.com/faizatastradot/bottlerocket-local-ssd-bootstrapper:v20"
    mode = "always"
    essential = true

This is the bootstrap script which is formatting and mounting the disk -

#!/usr/bin/env bash
set -ex

ROOT_PATH="/.bottlerocket/rootfs"

# The name of the disk we want to manage
DISK="${ROOT_PATH}/dev/nvme2n1"

# Mounts from this mount point will propagate accross mount namespaces
MOUNT_POINT=/.bottlerocket/rootfs/mnt/ephemeral

# Format disk to xfs
mkfs.xfs ${DISK}

# We make sure the target mount points exist
mkdir -p $MOUNT_POINT

# Always mount the partitions
mount -t xfs "${DISK}" "${MOUNT_POINT}"
