Can't extend VM storage

[williTheNose]

Hello,

I'm facing problems by trying to increase the storage of my VM image.

At first I set up the storage using dynamic increase. But I still run out of space at 5.6GB, I never saw it adjusting anything dynamically, maybe I set the maximum storage too low (read something like this somewhere).

So, I cloned it and increase the virtual drive size to 51200 MBytes (Clone of Ubuntu Server 15.1.vdi, see below). I checked the VM and ran out of space again at 5.6GB!

So, I cloned it again (again to 51200 MBytes) but this time also setting the option to increase partition size (Clone2 of Ubuntu Server 15.1.vdi). I checked the VM and ran out of space again at 5.6GB! What's going on?

Can anyone help?

read step 2 and then post the results of the following from the guests terminal.

df -h

Moving to Linux guests

What tool were you using to clone and "increase the partition size" of your Ubuntu server guest?

Given the terminology I'm suspecting you were using CloneVDI, which does not support expanding the filesystem of a EXTx (Linux) partition (sometimes it is useful to read the documentation that comes with software!). If you tick that option then CloneVDI will move other partitions around to make room for the expansion, but you have to use e.g. GParted to expand the EXTx partition itself.

[williTheNose]

Alright, thanks for your hints! Now, I have at least an idea how to solve it.

I downloaded the gparted live CD but unfortunately, gparted doesn't support partition resizing anymore (!!). Still looking for a way to do that.

but unfortunately, gparted doesn't support partition resizing anymore (!!)

I rather doubt that. The tool has no other purpose: "GNU Partition Editor".

You have never explicitly said what filesystem and partition method the guest uses. I have assumed EXTx and MBR since you evidently thought CloneVDI would handle it, but it would be a different kettle of fish if it was EXTx+LVM.

From the GParted home page:

With GParted you can resize, copy, and move partitions...

[Perryg]

You failed to provide the information I requested that would help in determining why you are having so much trouble.
Post the results of what df -h replies in the guest terminal.

[williTheNose]

Sorry, the information was not fully correct, I couldn't use gparted (missing X support), so I used parted instead and it told me:
Error: The resize command has been removed in parted 3.0

This is want I meant but there is a new option called resizepart, that should do as well (didn't noticed at first place).

And yes, I was using CloneVDI to clone and "increase the partition size". And yes, I use EXTx and LVM.

$ df -h

tmpfs           201M     0  201M   0% /run/user/1000

I put a lot of effort and time in it but I had to give it up as I have to make sure to get a working environment asap, so I set up a new VM with enough storage space. I'm just too stupid for this.

Thank you all for your help, I appreciate your support!

Your root volume /dev/dm-0 is only has a total size of 5.6GB so you cannot store anything bigger.

The next step is to use LVM to increase the partition size. Consult the OS help for the proper procedure.
