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 https://gitlab.com/qemu-project/qemu/-/issues/1621

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
José

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?
    Thanks
