GCE instance not using all the disk space

[Shambu Pujar]

Hi

I have a compute instance that was originally 10GB and then extended to 20GB. The extension doesn't seem to come in place . As seen in below , the OS is complaining about diskspace, while df -h comand shows more space

cp: cannot create directory '/app/node_modules/webpack-dev-server/lib': No space left on device

cp: cannot create directory '/app/node_modules/webpack-dev-server/bin': No space left on device

ERROR: Service 'ui' failed to build: The command '/bin/sh -c mkdir -p /app && cp -a /tmp/node_modules /app/' returned a non-zero code: 1

shambu@jenkins-1-vm-1:$ df -h

Filesystem      Size  Used Avail Use% Mounted on

/dev/sda1        20G   11G  7.8G  59% /

tmpfs           750M     0  750M   0% /run/user/1003

Not sure why remaining 7.8G is not used, or do i need to something to make it avaliable

Thanks

Hello Shambu,

When you resize a disk that is attached to an instance with the latest public images, and  according to this document, restarting the instance should be enough to automatically resize it’s partitions and file-systems with the exception of SUSE Linux Enterprise Server. Alternatively, to resize the partition and filesystem without rebooting, you can execute these commands:

sudo growpart /dev/sda 1   (space between disk ID and partition number)

sudo resize2fs /dev/sda1

Checking the output you provided, it seems that the disk is successfully resized, and it is rather a different file-system issue with your OS like running out of inodes. I found these community questions that could be helpful for your case [1] [2]. For further help, I encourage you to post your question at serverfault with the right Linux file-system tags, where you have access to a large community of enthusiasts and experts to share ideas with and get support from.
