Hi, 
Ok, discard is not enabled on the disk. 
Reading [ https://gitlab.com/qemu-project/qemu/-/issues/1621 | 
https://gitlab.com/qemu-project/qemu/-/issues/1621 ] 

I'm sure the image did not grow over 110% of its virtual size 

Any idea? 

Thanks 
José

Hi, 

Not talking about discard on the storage domain, but on disk/vm level. 
Is it enabled there? 

Cause if that is the cause, it could be [

Hi Jean-Louis, 

The VM disk is 300GB with 216GB available, preallocated on a iSCSI storage with 
3532GB total and 1932GB free. 
Have enable incremental backup. Discard After Delete is not enabled.

Hi Jose, 

How big are the disks? And what size are they on the storage? 
I guess the images are qcow2? 

Is discard enabled?

Hello, 

running ovirt Version 4.5.4-1.el8 on Centos 8, randomly we have this error: 
VM has been paused due to no Storage space error. 
We have plenty of space on the iSCSI storage. This is a preallocated disk, 
VirtIO-SCSi. 
No user interaction. It happens, so far, with 3 VM, Windows and Ubuntu. 
This service was stopped: dnf-makecache.service 

This is what I found on the engine log:

And we cannot start the VM anymore. 

Any idea?
