kubernetes node storage errors

8 Critical Kubernetes Node Storage Errors That Crash Clusters (Real Fixes – 2026)

by

Last Updated: January 2026

I’ll never forget the night our entire production cluster started evicting pods. 3 AM. Phone buzzing. Alerts screaming.

“Node disk full. Pods being evicted.”

I scrambled to my laptop, still half-asleep, to see 12 out of 15 nodes showing DiskPressure. Pods were getting killed left and right. Database connections dropping. API returning 503s. Full-blown outage.

The culprit? Docker images that nobody bothered to clean up. Over six months, we’d accumulated 180GB of unused container images on every node. Add application logs that weren’t being rotated, some stuck mounts from failed pods, and suddenly we went from 20% disk usage to 95% overnight.

Took me four hours to stabilize the cluster that night. Learned more about Kubernetes node storage than I ever wanted to know.

If you’re seeing “DiskPressure,” “eviction,” or “disk full” errors, you’re in the right place. Trough this article on Kubernetes Node Storage Errors Let me show you how to fix these issues and make sure they never wake you up at 3 AM.

Understanding Kubernetes Node Storage Errors (The Basics)

Kubernetes Node Storage Errors

Before we dive into errors, here’s what fills up your Kubernetes nodes:

Container Images – Every image you’ve ever pulled sits there forever (until cleaned)
Container Logs – stdout/stderr from your apps, can grow massive
Container Layers – Writable layers from running containers
Ephemeral Volumes – emptyDir, temp files, caches
Persistent Volumes – Attached storage (usually separate, but not always)
System Files – OS, kubelet logs, system temp files

When any of these fill up, bad things happen. Let’s fix them.

## 1. Node Has DiskPressure (Most common Kubernetes Node Storage Error )

What You’ll See

$ kubectl get nodes
NAME       STATUS                     ROLES    AGE
worker-1   Ready,SchedulingDisabled   <none>   45d
worker-2   Ready,DiskPressure         <none>   45d
worker-3   Ready                      <none>   45d

That “DiskPressure” status means the node is running out of disk space. Kubernetes won’t schedule new pods there, and it might start evicting existing ones.

Check What’s Happening

# Describe the node to see the details
kubectl describe node worker-2

# Look for this section:
Conditions:
  Type             Status  Reason                 Message
  ----             ------  ------                 -------
  DiskPressure     True    KubeletHasDiskPressure disk usage exceeds threshold

Why DiskPressure Triggers

Kubernetes monitors two thresholds:

Soft eviction threshold (default: 90% disk)

  • Warning state
  • New pods won’t be scheduled
  • Existing pods keep running

Hard eviction threshold (default: 95% disk)

  • Critical state
  • Kubernetes starts evicting pods
  • Evicts lowest priority pods first

The Quick Fix

# SSH to the node (or use kubectl debug)
kubectl debug node/worker-2 -it --image=ubuntu

# Check disk usage
df -h

# Common culprits:
Filesystem      Size  Used Avail Use% Mounted on
/dev/xvda1      100G   94G  6.0G  95% /
# ↑ This is your problem

Solution 1: Clean Up Docker/Containerd Images

# List all images and their sizes
crictl images | sort -k7 -h

# Remove unused images
crictl rmi --prune

# For Docker (older clusters)
docker system prune -a --volumes -f

This freed up 40GB for me that night.

Solution 2: Clean Up Old Container Logs

# Find large log files
find /var/log/pods -type f -size +100M -exec ls -lh {} \;

# Truncate huge logs (careful!)
find /var/log/pods -type f -size +500M -exec truncate -s 0 {} \;

# Or delete old pod logs
find /var/log/pods -type f -mtime +7 -delete

Solution 3: Configure Automatic Cleanup

Edit kubelet configuration:

# /var/lib/kubelet/config.yaml
imageGCHighThresholdPercent: 85  # Start GC when disk at 85%
imageGCLowThresholdPercent: 80   # Stop GC when disk at 80%
imageMinimumGCAge: 2m            # Don't GC images newer than 2min
evictionHard:
  imagefs.available: "10%"       # Evict pods if <10% free
  nodefs.available: "10%"
evictionSoft:
  imagefs.available: "15%"       # Soft warning at 15%
  nodefs.available: "15%"
evictionSoftGracePeriod:
  imagefs.available: "2m"
  nodefs.available: "2m"

Restart kubelet:

systemctl restart kubelet

Solution 4: Increase Disk Size (Last Resort)

If you’ve cleaned everything and still hitting limits:

# For AWS EBS
aws ec2 modify-volume --volume-id vol-xyz --size 200

# Then expand the filesystem
sudo resize2fs /dev/xvda1

# For GCP
gcloud compute disks resize disk-name --size=200GB

## 2. Node Disk Full (Disk Gets Full)

The Error

$ kubectl describe pod app-xyz
Events:
  Warning  FailedCreatePodSandBox  Failed to create pod sandbox: 
  rpc error: code = Unknown desc = failed to create containerd task: 
  write /var/lib/containerd: no space left on device

This is worse than DiskPressure. The disk is actually full – 100% used. Nothing can write.

Immediate Triage

# Check which filesystem is full
kubectl debug node/worker-2 -it --image=ubuntu
df -h

# Find what's eating space
du -sh /* | sort -h | tail -20

# Common hogs:
# /var/lib/containerd  (or /var/lib/docker)
# /var/log
# /tmp

My Emergency Cleanup Script

I keep this handy for emergencies:

#!/bin/bash
# emergency-cleanup.sh

echo "=== Disk Usage Before ==="
df -h /

echo "=== Cleaning container images ==="
crictl rmi --prune
# or: docker system prune -a -f

echo "=== Cleaning old logs ==="
journalctl --vacuum-time=2d
find /var/log/pods -type f -mtime +3 -delete
find /tmp -type f -mtime +1 -delete

echo "=== Cleaning dead containers ==="
crictl rm $(crictl ps -a -q --state=exited)

echo "=== Disk Usage After ==="
df -h /

Finding the Space Hogs

# Top 20 largest directories
du -ah /var | sort -h | tail -20

# If containerd/docker is huge:
du -sh /var/lib/containerd/*
# or
du -sh /var/lib/docker/*

# If logs are huge:
du -sh /var/log/*

Real Example from My 3 AM Incident

$ du -sh /var/lib/containerd/*
12G    /var/lib/containerd/io.containerd.snapshotter.v1.overlayfs
156G   /var/lib/containerd/io.containerd.content.v1.content
#      ↑ 156GB of container images!

# Cleaned up unused images
$ crictl rmi --prune
Deleted: sha256:abc123... (45GB)
Deleted: sha256:def456... (32GB)
Deleted: sha256:ghi789... (28GB)

$ du -sh /var/lib/containerd/*
12G    /var/lib/containerd/io.containerd.snapshotter.v1.overlayfs
51G    /var/lib/containerd/io.containerd.content.v1.content
#      ↑ Down to 51GB - freed 105GB!

## 3. Image Filesystem Full (Container Image Filesystem Gets Full)

The Error

$ kubectl describe node worker-2
Conditions:
  Message: ImageGCFailed: wanted to free 12685876224 bytes, but freed 0 bytes
  Reason:  ImageGCFailed

The container image filesystem is full, and garbage collection isn’t helping.

Why This Happens

Problem 1: Images in use can’t be deleted

All your pods are using different images, so there’s nothing to GC.

# See what images are in use
crictl images | grep -v "SIZE"
# Every image here is being used by at least one pod

Problem 2: Many large images

crictl images | sort -k7 -hr | head -10
# You might see images like:
# tensorflow:2.9  15GB
# cuda-base:11.8  12GB
# ml-model:v3     8GB

The Fix

Option 1: Use smaller base images

# Before
FROM python:3.9
# Image size: 915MB

# After
FROM python:3.9-slim
# Image size: 122MB

# Even better
FROM python:3.9-alpine
# Image size: 47MB

Option 2: Set image pull policy

apiVersion: v1
kind: Pod
metadata:
  name: myapp
spec:
  containers:
  - name: app
    image: myapp:v1.0.0  # Use specific tags!
    imagePullPolicy: IfNotPresent  # Don't pull if exists

Option 3: Use a separate partition for images

Mount a larger volume for container images:

# Create and mount larger volume for /var/lib/containerd
# This way image storage doesn't compete with system storage

Option 4: Implement image pruning cronjob

apiVersion: batch/v1
kind: CronJob
metadata:
  name: image-cleanup
  namespace: kube-system
spec:
  schedule: "0 2 * * *"  # 2 AM daily
  jobTemplate:
    spec:
      template:
        spec:
          hostPID: true
          hostNetwork: true
          hostIPC: true
          containers:
          - name: cleanup
            image: busybox
            command:
            - nsenter
            - --target
            - "1"
            - --mount
            - --uts
            - --ipc
            - --net
            - --pid
            - --
            - crictl
            - rmi
            - --prune
            securityContext:
              privileged: true
          restartPolicy: OnFailure
          nodeSelector:
            node-role.kubernetes.io/worker: "true"

## 4. Ephemeral Storage Exceeded (Why My Pod Gets Evicted Suddenly)

The Error

$ kubectl describe pod myapp-xyz
Status:    Failed
Reason:    Evicted
Message:   Pod ephemeral local storage usage exceeds the total limit of containers 1Gi

Your pod was using too much ephemeral storage (emptyDir, logs, temp files) and got evicted.

What Is Ephemeral Storage?

Everything that’s not a persistent volume:

  • emptyDir volumes
  • Container logs (stdout/stderr)
  • Container writable layer (files created inside container)
  • /tmp and /var/tmp inside containers

Check Current Usage

# See pod's ephemeral storage usage
kubectl describe pod myapp-xyz | grep -A 10 "Ephemeral Storage"

# Example output:
Ephemeral Storage:  1.5Gi  # Used
Limits:             1Gi    # Allowed - EXCEEDED!

The Fix

Solution 1: Increase ephemeral storage limit

apiVersion: v1
kind: Pod
metadata:
  name: myapp
spec:
  containers:
  - name: app
    image: myapp:latest
    resources:
      requests:
        ephemeral-storage: "2Gi"  # Request
      limits:
        ephemeral-storage: "4Gi"  # Limit

Solution 2: Use persistent volume instead of emptyDir

# Before - using emptyDir
volumes:
- name: cache
  emptyDir: {}

# After - using PVC
volumes:
- name: cache
  persistentVolumeClaim:
    claimName: cache-pvc

Solution 3: Clean up temp files regularly

apiVersion: v1
kind: Pod
metadata:
  name: myapp
spec:
  containers:
  - name: app
    image: myapp:latest
    lifecycle:
      preStop:
        exec:
          command: ["/bin/sh", "-c", "rm -rf /tmp/*"]
  - name: cleaner
    image: busybox
    command:
    - sh
    - -c
    - while true; do find /tmp -mtime +1 -delete; sleep 3600; done
    volumeMounts:
    - name: tmp
      mountPath: /tmp
  volumes:
  - name: tmp
    emptyDir: {}

Solution 4: Reduce log verbosity

env:
- name: LOG_LEVEL
  value: "INFO"  # Instead of DEBUG

My Logging Lesson

We had a Java app that logged every SQL query in debug mode. In production. 50,000 requests per minute. Each request had 10+ queries. That’s 500,000 log lines per minute.

One pod filled up 10GB in ephemeral storage in under an hour. Got evicted. Restarted. Filled up again. Evicted. Loop.

Changed LOG_LEVEL to INFO. Problem solved. Felt stupid.

## 5. Kubelet Volume Cleanup Failed (The Volume is Still there)

The Error

$ kubectl describe node worker-2
Events:
  Warning  VolumeCleanupFailed  Orphaned pod "abc-123" found, but error occurred during volume cleanup: 
  error cleaning volume mounts: context deadline exceeded

Kubelet couldn’t clean up volumes from deleted pods. They’re stuck on the node.

Why This Happens

  • Pod deleted but containers still running
  • Volumes still mounted (busy)
  • NFS server unreachable
  • Device still attached to old process

Check for Orphaned Volumes

kubectl debug node/worker-2 -it --image=ubuntu

# Check kubelet volume directory
ls -la /var/lib/kubelet/pods/
# You'll see directories for pods that don't exist anymore

# Check what's mounted
mount | grep kubelet
# Look for orphaned mounts

The Fix

Step 1: Try graceful cleanup

# Restart kubelet (it will retry cleanup)
systemctl restart kubelet

# Wait a minute, check if cleaned up
ls /var/lib/kubelet/pods/

Step 2: Force unmount stuck volumes

# Find stuck mounts
mount | grep kubelet | grep "abc-123"

# Force unmount
umount -f /var/lib/kubelet/pods/abc-123-def-456/volumes/kubernetes.io~csi/pvc-xyz/mount

# If that fails, lazy unmount
umount -l /var/lib/kubelet/pods/abc-123-def-456/volumes/kubernetes.io~csi/pvc-xyz/mount

Step 3: Clean up orphaned directories

# Get list of current pods
kubectl get pods -A -o json | jq -r '.items[].metadata.uid' | sort > /tmp/active-pods

# Get list of pod directories
ls /var/lib/kubelet/pods/ | sort > /tmp/pod-dirs

# Find orphans
comm -13 /tmp/active-pods /tmp/pod-dirs > /tmp/orphans

# Remove orphaned directories (careful!)
while read pod_uid; do
  echo "Removing orphaned pod directory: $pod_uid"
  rm -rf /var/lib/kubelet/pods/$pod_uid
done < /tmp/orphans

Step 4: Prevent future issues

Set proper termination grace period:

apiVersion: v1
kind: Pod
metadata:
  name: myapp
spec:
  terminationGracePeriodSeconds: 30  # Give time to cleanup
  containers:
  - name: app
    image: myapp:latest

## 6. Mount Propagation Failed (A Tricky Error)

The Error

$ kubectl describe pod myapp-xyz
Events:
  Warning  FailedMount  MountVolume.SetUp failed: 
  rpc error: code = Internal desc = mount propagation not set correctly

This is a tricky one. Mount propagation controls how mounts are shared between host and containers.

What Mount Propagation Does

  • None – No propagation (default, usually works)
  • HostToContainer – Host mounts visible in container
  • Bidirectional – Mounts shared both ways

Why It Fails

Usually happens when:

  • kubelet started without proper mount propagation support
  • Node OS doesn’t support mount propagation
  • systemd configuration wrong

Check Mount Propagation

# On the node
cat /proc/self/mountinfo | grep kubelet

# Look for "shared:" tag
# If missing, propagation isn't working

The Fix

Step 1: Enable mount propagation in kubelet

# Edit kubelet systemd service
vi /etc/systemd/system/kubelet.service.d/10-kubeadm.conf

# Make sure MountFlags is set correctly:
[Service]
MountFlags=shared

# Reload and restart
systemctl daemon-reload
systemctl restart kubelet

Step 2: Check Docker/containerd configuration

# For Docker
cat /etc/docker/daemon.json
{
  "storage-driver": "overlay2",
  "exec-opts": ["native.cgroupdriver=systemd"],
  "features": {
    "buildkit": true
  }
}

# Restart Docker
systemctl restart docker

Step 3: Use correct mount propagation in pod

apiVersion: v1
kind: Pod
metadata:
  name: myapp
spec:
  containers:
  - name: app
    image: myapp:latest
    volumeMounts:
    - name: data
      mountPath: /data
      mountPropagation: HostToContainer  # Explicitly set

When I Hit This

We were running Kubernetes on custom Linux distro. Mount propagation wasn’t compiled into the kernel. Took a whole day to figure out. Rebuilt kernel with proper flags. Never again.

## 7. Stale Mounts on Node (Hidden Volume KIller)

The Symptoms

# Pod gets stuck
$ kubectl get pods
NAME        READY   STATUS              RESTARTS   AGE
myapp-xyz   0/1     ContainerCreating   0          5m

# Events show:
Warning  FailedMount  Unable to attach or mount volumes: 
unmount failed: exit status 1
Unmounting arguments: /var/lib/kubelet/pods/.../volumes/...
Output: target is busy

Old mounts from deleted pods are still there, preventing new pods from starting.

How This Happens

  1. Pod deleted
  2. Volume unmount fails (maybe NFS was down)
  3. Mount point still exists
  4. New pod tries to use same volume
  5. Can’t mount (path busy)

Find Stale Mounts

kubectl debug node/worker-2 -it --image=ubuntu

# List all kubelet mounts
mount | grep kubelet

# Compare with actual running pods
kubectl get pods -o wide | grep worker-2

# Mounts for non-existent pods = stale

The Fix

Option 1: Unmount and clean up

# Find the stale mount
mount | grep "pvc-abc123"

# Kill any processes using it
lsof /var/lib/kubelet/pods/.../volumes/.../mount
kill -9 <PID>

# Unmount
umount /var/lib/kubelet/pods/.../volumes/.../mount

# If busy, force it
umount -f /var/lib/kubelet/pods/.../volumes/.../mount

# If still busy, lazy unmount (last resort)
umount -l /var/lib/kubelet/pods/.../volumes/.../mount

Option 2: Restart kubelet

# Kubelet restart will retry cleanup
systemctl restart kubelet

# Check if mounts cleaned up
mount | grep kubelet

Option 3: Node reboot (nuclear option)

# Cordon node first
kubectl cordon worker-2

# Drain pods
kubectl drain worker-2 --ignore-daemonsets --delete-emptydir-data

# Reboot
sudo reboot

# After reboot, uncordon
kubectl uncordon worker-2

Prevention

Set shorter finalizer timeouts:

apiVersion: v1
kind: Pod
metadata:
  name: myapp
  finalizers:
  - kubernetes.io/pvc-protection  # Ensures cleanup
spec:
  terminationGracePeriodSeconds: 30

Monitor for stale mounts:

# Create monitoring script
#!/bin/bash
# check-stale-mounts.sh

ACTIVE_PODS=$(kubectl get pods -A -o json | jq -r '.items[].metadata.uid')

for mount in $(mount | grep kubelet | awk '{print $3}'); do
  POD_UID=$(echo $mount | grep -oP '/pods/\K[^/]+')
  if ! echo "$ACTIVE_PODS" | grep -q "$POD_UID"; then
    echo "Stale mount found: $mount"
    # Alert or cleanup
  fi
done

## 8. Node Reboot Causing Volume Attach Failure

The Problem

# After node reboots
$ kubectl get pods
NAME        READY   STATUS              RESTARTS   AGE
myapp-xyz   0/1     ContainerCreating   0          5m

$ kubectl describe pod myapp-xyz
Events:
  Warning  FailedAttachVolume  Multi-Attach error: 
  volume is still attached to node "worker-2-old" but node is gone

Node rebooted (or crashed), but Kubernetes thinks volumes are still attached to the old node.

Why This Happens

  1. Node crashes or reboots unexpectedly
  2. Volumes attached to that node (EBS, PD, etc.)
  3. Cloud provider doesn’t know node is dead
  4. Volumes stuck in “attached” state to dead node
  5. Can’t attach to new node

Check Volume Attachments

# See volume attachments
kubectl get volumeattachment

NAME        ATTACHER           PV        NODE        ATTACHED
csi-abc     ebs.csi.aws.com    pvc-xyz   worker-2    true
# If worker-2 is dead but ATTACHED=true, that's the problem

The Fix

Option 1: Delete stale VolumeAttachment

# Delete the attachment
kubectl delete volumeattachment csi-abc

# Volume will detach from dead node
# Then reattach to new node automatically

Option 2: Force detach in cloud provider

For AWS:

# Get volume ID
kubectl get pv pvc-xyz -o jsonpath='{.spec.csi.volumeHandle}'

# Force detach
aws ec2 detach-volume --volume-id vol-abc123xyz --force

# Delete VolumeAttachment in Kubernetes
kubectl delete volumeattachment csi-abc

For GCP:

# Get disk name
kubectl get pv pvc-xyz -o jsonpath='{.spec.csi.volumeHandle}'

# Detach disk
gcloud compute instances detach-disk old-node-name --disk=disk-name

# Delete VolumeAttachment
kubectl delete volumeattachment csi-abc

Option 3: Delete and recreate the pod

# Force delete pod
kubectl delete pod myapp-xyz --force --grace-period=0

# Recreate (if part of deployment, it happens automatically)

Prevention

Set proper timeouts:

# In CSI driver configuration
--timeout=300s  # Wait 5 minutes before giving up

Use pod disruption budgets:

apiVersion: policy/v1
kind: PodDisruptionBudget
metadata:
  name: myapp-pdb
spec:
  minAvailable: 1
  selector:
    matchLabels:
      app: myapp

Monitor node health:

# Alert on NotReady nodes
kubectl get nodes -o json | jq -r '
  .items[] | 
  select(.status.conditions[] | 
    select(.type=="Ready" and .status!="True")) | 
  .metadata.name
'

Quick Troubleshooting Checklist

When nodes have storage issues:

# 1. Check node conditions
kubectl describe node <node-name> | grep -A 10 Conditions

# 2. Check disk usage
kubectl debug node/<node-name> -it --image=ubuntu
df -h

# 3. Find what's using space
du -sh /* | sort -h | tail -10

# 4. Check for DiskPressure
kubectl get nodes | grep DiskPressure

# 5. Check ephemeral storage usage
kubectl describe pod <pod-name> | grep -i ephemeral

# 6. Check for stale mounts
mount | grep kubelet

# 7. Check volume attachments
kubectl get volumeattachment

# 8. Check for orphaned pods
ls /var/lib/kubelet/pods/ | wc -l
kubectl get pods -A | wc -l
# If first number way bigger = orphaned pods

My Node Health Monitoring Script

I run this on a cronjob to catch issues early:

#!/bin/bash
# node-health-check.sh

for node in $(kubectl get nodes -o name); do
  NODE_NAME=$(basename $node)
  
  # Check disk pressure
  if kubectl get node $NODE_NAME -o json | jq -r '.status.conditions[] | select(.type=="DiskPressure") | .status' | grep -q True; then
    echo "ALERT: $NODE_NAME has DiskPressure"
    # Send alert
  fi
  
  # Check disk usage (requires metrics-server)
  DISK_USAGE=$(kubectl top node $NODE_NAME --no-headers | awk '{print $5}' | tr -d '%')
  if [ $DISK_USAGE -gt 80 ]; then
    echo "WARNING: $NODE_NAME disk at ${DISK_USAGE}%"
    # Send warning
  fi
  
  # Check for stale pods
  kubectl debug node/$NODE_NAME -q -- sh -c '
    ACTIVE=$(curl -s localhost:10250/pods | jq ".items | length")
    ON_DISK=$(ls /var/lib/kubelet/pods | wc -l)
    if [ $ON_DISK -gt $((ACTIVE + 10)) ]; then
      echo "WARNING: $NODE_NAME has orphaned pod directories"
    fi
  '
done

Best Practices I Follow Now

1. Set Resource Limits on Everything to Prevent Kubernetes Node Storage errors 

resources:
  requests:
    ephemeral-storage: "1Gi"
  limits:
    ephemeral-storage: "2Gi"

2. Configure Kubelet Garbage Collection to minimize Kubernetes Node Storage errors 

# /var/lib/kubelet/config.yaml
imageGCHighThresholdPercent: 85
imageGCLowThresholdPercent: 80
evictionHard:
  nodefs.available: "10%"
  imagefs.available: "10%"

3. Use Log Rotation

apiVersion: v1
kind: Pod
metadata:
  name: myapp
spec:
  containers:
  - name: app
    image: myapp:latest
    # In Dockerfile or command:
    # Configure log rotation
    # Use structured logging
    # Send logs to external system

4. Monitor Disk Usage to Prevent Kubernetes Node Storage errors 

# Prometheus alerts
- alert: NodeDiskPressure
  expr: kube_node_status_condition{condition="DiskPressure",status="true"} == 1
  for: 5m
  
- alert: NodeDiskUsageHigh
  expr: (1 - node_filesystem_avail_bytes / node_filesystem_size_bytes) > 0.85
  for: 10m

5. Regular Node Maintenance for Prevention From Kubernetes Node Storage errors 

# Weekly cleanup script
kubectl apply -f - <<EOF
apiVersion: batch/v1
kind: CronJob
metadata:
  name: node-cleanup
  namespace: kube-system
spec:
  schedule: "0 3 * * 0"  # Sunday 3AM
  jobTemplate:
    spec:
      template:
        spec:
          hostPID: true
          hostNetwork: true
          containers:
          - name: cleanup
            image: ubuntu
            command:
            - bash
            - -c
            - |
              crictl rmi --prune
              journalctl --vacuum-time=7d
              find /var/log/pods -mtime +7 -delete

Final Thoughts About Kubernetes Node Storage errors

Kubernetes Node storage errors taught me that Kubernetes isn’t magic. It’s running on real servers with real disks that fill up with real garbage.

That 3 AM wake-up call cost us 4 hours of downtime and taught me:

Prevention for Kubernetes Node Storage errors:

  • Monitor disk usage before it’s a problem
  • Set up garbage collection correctly
  • Use ephemeral storage limits
  • Clean up regularly

When it breaks:

  1. Check disk usage first (df -h)
  2. Find what’s using space (du -sh /*)
  3. Clean up images (crictl rmi --prune)
  4. Check for orphaned mounts
  5. Restart kubelet if needed

The best fix: Don’t let Kubernetes Node Storage errors happen. Set up monitoring, configure kubelet properly, and have cleanup scripts ready. This will help us identify the kubernetes node storage errors quickly.

I haven’t had a Kubernetes Node Storage errors outages since implementing these practices. Knock on wood.
