How to Resize Deejay of a VM Instance in Google Cloud. In this guide you are going to learn how to resize the disk space of your Compute Engine instance on the fly without whatever reanimation.

You can too attach and mount new additional deejay to your example instead of resizing your disk.

Prerequisites

  1. SSH access to your VM Instance.
  2. Backup your disk by creating a snapshot of your deejay. You can also setup automatic snapshot schedules.
  3. Basic SSH final skills to execute commands.

Important: Yous can only enlarge the size of the existing disk, y'all cannot shrink your deejay to lower size.

Stride ane: Check Disk Size

Earlier resizing your disk size you can check your available disk infinite so you lot will get an idea almost the available space in your deejay. Information technology is recommended to increment the size if your used space is more than 80%.

Execute the following command to check the deejay space.

df -h

You will get an output similar to the ane beneath.

          Output          Filesystem      Size  Used Avail Use% Mounted on udev            286M     0  286M   0% /dev tmpfs            60M  2.4M   57M   iv% /run          /dev/sda1          9.8G          1.1G  8.2G  12% / tmpfs           297M     0  297M   0% /dev/shm tmpfs           5.0M     0  5.0M   0% /run/lock tmpfs           297M     0  297M   0% /sys/fs/cgroup

Here /dev/sda1 is the one which shows the available and used infinite of your disk. I tested this on a new fresh disk with 10GB space.

Step 2: Check Partitioning

Now you lot demand to check the partitions available on the your disk.

lsblk

This control shows the available partitions. You volition get an output similar to this.

          Output          Proper noun   MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda      8:0    0  10G  0 disk  └─sda1   eight:1    0  10G  0 function /

In this case we having merely one division.

As yous can come across, sda is the DEVICE_ID and one is the partition number.

Step three: Increase Deejay Size

Go to your Google Deject Console and navigate to Compute >> VM Instances.

Click the proper noun of the instance where you want to add together a deejay.

Curlicue down to Boot deejay and click on the disk name.

At present you will be taken to the Disk Management folio.

Click Edit on the top.

Hither you can specify the size of you lot need.

Click Relieve in the bottom to utilise the changes.

Pace 4: Grow Sectionalisation

Now you need to resize the sectionalization using the growpart command with your device id and division number.

sudo growpart /dev/sda          1

You volition get something like.

          Output          Changed: partition=ane start=4096 sometime: size=20967424 stop=20971520 new: size=1048571871,terminate=1048575967

Step 5: Resize File System

The last stride is to resize the filesystem with the resize2fs command.

sudo resize2fs /dev/sda1

The output will exist similar this.

          Output          resize2fs 1.43.4 (31-Jan-2017) Filesystem at /dev/sda1 is mounted on /; on-line resizing required old_desc_blocks = 2, new_desc_blocks = 63 The filesystem on /dev/sda1 is now 131071483 (4k) blocks long.

Step vi: Verify the Setup

At present you can verify the deejay space using the df control. Your disk space must have rezised to the boosted infinite you added.

df -h
          Output          Filesystem      Size  Used Avail Use% Mounted on udev            286M     0  286M   0% /dev tmpfs            60M  ii.4M   57M   four% /run /dev/sda1          493G          1.2G  471G   1% / tmpfs           297M     0  297M   0% /dev/shm tmpfs           five.0M     0  5.0M   0% /run/lock tmpfs           297M     0  297M   0% /sys/fs/cgroup

Conclusion

Now you lot have learned how to resize your VM Instance without restarting and without downtime.
