GCP Create Filestore

GCP Cloud Filestore is a managed file storage service for applications that require a filesystem interface and a shared filesystem for data. Filestore gives users a simple, native experience for standing up managed Network Attached Storage (NAS) with their Google Compute Engine and Kubernetes Engine instances.

With that said, let’s build one.

gcloud filestore instances create nfs-server \
  --project=[PROJECT_ID] \
  --zone=us-central1-c \
  --tier=STANDARD \
  --file-share=name="vol1",capacity=1TB \
  --network=name="default"

How to mount the filestore on clients.

sudo apt-get -y update
sudo apt-get -y install nfs-common
sudo mkdir /mnt/test
sudo mount 10.0.0.2:/vol1 /mnt/test
sudo chmod go+rw /mnt/test

Increase capacity to 3TB.

gcloud filestore instances update nfs-server 
  --project=myproject 
  --zone=us-central1-c 
  --file-share=name="vol1",capacity=3TB

Tar Commands

Here are two important tar commands on how to create and extract a tar.gz file.

Create a tar gzip file called “project.tar.gz” of a directory called “foo.”

tar -cvzf project.tar.gz foo

Untar the “project.tar.gz” file to a directory called bar.

tar -zxvf project.tar.gz bar

GCP Create Instance From Snapshot

There are two steps in creating an instance from a snapshot.

  1. Create a disk from snapshot
  2. Create an instance from the disk

Create a disk from snapshot.

gcloud compute disks create "hostname-boot" \
--project "project-id" \
--zone "us-central1-a" \
--source-snapshot "snapshot-name" \
--type "pd-standard" \
--size "100"

Create an instance from disk.

gcloud beta compute instances create hostname \
--project=project-id \
--zone=us-central1-a \
--subnet=your-subnetwork \
--machine-type=n1-standard-1 \
--no-address \
--maintenance-policy=MIGRATE \
--service-account=service.account@developer.gserviceaccount.com \
--disk=name=instance-1,device-name=instance-1,mode=rw,boot=yes,auto-delete=yes \
--reservation-affinity=any \
--labels=builtby=john.doe \
--tags=web \
--scopes= \
--metadata=

GCP Convert Standard to SSD

How to convert Persistent Standard disk to SSD.

First create a snapshot of the disk.

gcloud compute disks snapshot your-server \
--snapshot-names manual-snapshot-disk-1 \
--project your-project \
--zone us-central1-c

Restore snapshot to SSD format.

gcloud compute disks create disk-1-ssd \
--source-snapshot manual-snapshot-disk-1 \
--project your-project \
--zone us-central1-a \
--type pd-ssd \
--size 10GB

Swap disks using GCP attach and detach.
