The given answer: 
Resolution 

    * Please upgrade to RHV 4.4 SP1. Newer improvements greatly reduced the delays during
extensions and the default values were changed to accomodate modern hardware. The tuning
suggested below should be reverted after upgrading to RHV 4.4 SP1, in case it was applied.

    * Recent testing shows the latest RHV 4.4 SP1 can handle up to 1300MiB/s of writes
without pausing. If the VM is expected to constantly write values around or higher than
this, please use RAW preallocated volumes.

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

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. 

Thanks

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?
