Hi, I have the same problem with thin provisioned VMs (or VMs with snapshot) It got a lot better (but not fixed) using this guide https://access.redhat.com/solutions/130843 to adjust the tunables
Maybe it helps Christian Von: [email protected] [mailto:[email protected]] Im Auftrag von Yaniv Kaul Gesendet: Montag, 07.

Almost all vms are using thin provisioning with a virtual size of 40GB and a typical physical size of 8 GB. Now I’m facing the fact that ovirt is pausing my vms due to the following event message: (Example): “VM vm_01_16_centos6 has been paused due to no Storage space error.” oVirt is not pausing VMs. QEMU/KVM does, when it gets a storage error (in order to prevent possible corruption). Can you please attach VDSM logs from the relevant host where this is happening? TIA, Y. When I look at the iscsi storage domain the over allocation ratio value is about 127%, but of the 2799GB there is still more than 1500GB available. My questions: - Why ovirt is pausing the vms? - Can I enlarge the over allocation ratio before ovirt is complaining about storage space? _______________________________________________ Users mailing list [email protected]<mailto:[email protected]> http://lists.ovirt.org/mailman/listinfo/users
