Hello, I am using a VM image provided by SAP on google cloud which runs on SUSE. The original configuration of the image was 36 GB, however when I created the image I increased it to 120 GB as I knew I will have to install few other components to it. When I ssh into the system I see that the /dev/sda1 is allocated only 36GB. `> df -h Filesystem Size Used Avail Use% Mounted on devtmpfs 13G 0 13G 0% /dev tmpfs 13G 0 13G 0% /dev/shm tmpfs 13G 9.7M 13G 1% /run tmpfs 13G 0 13G 0% /sys/fs/cgroup /dev/sda1 36G 33G 661M 99% / tmpfs 2.6G 0 2.6G 0% /run/user/490 tmpfs 2.6G 0 2.6G 0% /run/user/1004 tmpfs 2.6G 0 2.6G 0% /run/user/1005 ` But the disksize available is 120GB. `> sudo lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 120G 0 disk └─sda1 8:1 0 36G 0 part / ` How do I allocate more space from sda to sda1 ? ---

Could you show us the partition table for the disk/device as well as the filesystems in use? ```auto fdisk -l /dev/sda mount | grep sda ``` The things I usually try include using ‘yast disk’ (Partitioner) to resize the disk, though that may not work for the root filesystem while it is online, and may depend on the filesystem used and partitions on the disk (see commands above), or else I would try ‘parted’. – Good luck.

[color=blue] > Code: > --------------------[color=green] > \> mount | grep sda[/color] > /dev/sda1 on / type ext4 (rw,relatime,data=ordered) > --------------------[/color] The only question remaining is whether or not this can be done, with ext4 or even just the partition under it, while the system is running from that partition. I’m 99.999% sure you can do it if you were to boot from other media, but I do not know how you would do that with a Google Compute (or any other cloud) instance; if you can do it online, then try Yast’s Partitioner first: ```auto sudo /sbin/yast disk ``` else, try ‘parted’. – Good luck.

I don’t think booting from other device is an option unfortunately. Here is what google says about [resizing](https://cloud.google.com/compute/docs/disks/add-persistent-disk). [Resizing root disk.](https://cloud.google.com/compute/docs/disks/create-root-persistent-disks#resizingrootpd) This is [the image](https://console.cloud.google.com/launcher/details/sap-public/sap-hana-express?project=hxe-project) that I used to create my system. The default on it was 36GB which I increased to 120 while creating my instance. But it still assigned 36 to root disk while keeping rest of it for itself. I followed the second link option and changed it to 125 GB but it still kept extra 5 gigs for itself 😃 ---

If not, my next push would be to create a new persistent disk, mount it where you need it, and then use that going forward since, in my experience, this works better on all types of systems (physical virtual, etc.) since 99.9% of reasons to grow disks are application-specific, meaning they have their own directories where large data things reside (binary data like databases or VMs or images) and that is ideally suited to the flexibility that comes from mountpoints. – Good luck.

I also think the resizing is done because when I use resize2fs it says the filesystem is already 9435923 blocks long which makes me think I just need to allocate more space to the partition somehow. I contacted google support and they ask me to use gcloud api command `gcloud compute disks resize `. But apparentlyresize is not a valid parameter 😛 I have contacted them again and I will probably create another disk if need be. But this I assumed should have been easier than all the hoops I am jumping through specially when the instance was created with sufficient space to begin with. Edit: I just saw [this page](https://cloud.google.com/compute/docs/disks/create-root-persistent-disks#resizingrootpd) . It lists the OS which support automatic resizing. Do you think SUSE is the reason its not happening? ---

HI frable90, resize the partition to reach to the end of the disk, then reboot, then resize the file system. Alternatively, switch to using more than one file system. You’d create additional partitions on the disk and use it for the additional file systems, or start using LVM for that (which I’d recommend anyhow, despite this being a cloud machine). Regards, J
