Increase Diskspace in Cloud Environment- no server restart

Disk space issues still exists. Although we have defined good disk space. Some bad application would outrun the estimation & cause disk full on the critical components. We recently faced issue with RabbitMQ server. Where one of the bad application has started piling data on one Queue. If we restart other application also get impacted. So needed online diskspace increase.

Get disk details

On GKE:

Setup Credentials

gcloud auth activate-service-account --key-file=test-project.json

gcloud config set project my-project-1234

Get Name of Troubled disk

gcloud beta compute ssh --zone “us-central1-a” instance-10 df -h

gcloud compute instances describe instance-10 |grep disk

Increase space to disk

gcloud compute disks resize instance-10-disk --size 100GB

gcloud beta compute ssh --zone “us-central1-a” instance-10 lsblk

Increase space based on OS (Applies to all cloud)
