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
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 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.
