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)'

Extend Regional Persistent Disks

Here’s the command to extend your regional persistent disks.

gcloud compute disks resize disk-name \
--size 100 \
--project project-id \
--region us-central1

Display the updated disk details.

gcloud compute disks list \
--filter="name=disk-name" \
--project project-id
