GCP Identify Your Disks

Here’s how to identify your disks on the system to cross check with GCP Dashboard.

ls -l /dev/disk/by-id

Result:

[root@servername ~]# ls -l /dev/disk/by-id
total 0
lrwxrwxrwx. 1 root root  9 Sep 15 05:30 google-boot -> ../../sda
lrwxrwxrwx. 1 root root 10 Sep 15 05:30 google-boot-part1 -> ../../sda1
lrwxrwxrwx. 1 root root  9 Sep 15 05:30 google-persistent-disk-1 -> ../../sdb
lrwxrwxrwx. 1 root root  9 Sep 15 05:30 scsi-0Google_PersistentDisk_boot -> ../../sda
lrwxrwxrwx. 1 root root 10 Sep 15 05:30 scsi-0Google_PersistentDisk_boot-part1 -> ../../sda1
lrwxrwxrwx. 1 root root  9 Sep 15 05:30 scsi-0Google_PersistentDisk_persistent-disk-1 -> ../../sdb

GCP Disks Attach To An Instance

Here’s how to display a list the disks attached to an instance.

gcloud compute instances describe instance-name \
--project project-id \
--zone us-central1-c \
--format='yaml(disks[].source)'

GCP Create Instance With Reservations

Here’s how to create an instance with CUD (committed used discounts) reservations.

gcloud compute instances create instance-name \
--no-address \
--private-network-ip 10.0.0.24 \
--source-machine-image=projects/project-id/global/machineImages/image-name \
--subnet=https://www.googleapis.com/compute/v1/projects/your-project/regions/us-central1/subnetworks/your-sub-network \
--machine-type=n1-standard-4 \
--reservation-affinity=specific \
--reservation=your-reservation-name \
--zone=us-central1-a \
--project=your-project-id
