So, I've made a mistake. I used the web-GUI to extend storage of one of my VM's, and instead of adding 100GB, I added 1000GB!. The physical disk isn't this big. How can I resize disk and bring the number back down to something reasonable?

Hi, shrinking is not supported from the GUI.
As long as you haven't extended the file system inside the VM, I think just putting back a smaller number in the .conf file should work.
If you have already increased the filesystem, what I would recommend (off the top of my head) is:
* reduce the filsystem size to below what you need
* stop the VM
* manually edit the .conf file to set the disk size to a little more than the FS size.
* start the VM and realign the FS to match the disk size.
Caution: If it was me, I would first try this in a separate VM to get confidence when I try it with my "real" VM

Hi Thanks for the reply. I manually edited the .conf file, and set the disk size to original, and it seemed fixed in the GUI, showing 200G. However, I I then ran the command qm resize 113 scsi0 +100G and got a disturbing message, which I've attached. Whenever I do an fdisk, this extra size is not shown. However, whenever I do a cfdisk on the VM, I have the second attached image.
