Hi Oliver, can you check your version of UI ? It seems that both VMs I had created are fully "Preallocated" instead of being "Thin Provisioned". Can someone lead me what section of bugzilla should I open the bug ? Here is some output: [root@ovirt1 images]# qemu-img info /rhev/data-center/mnt/glusterSD/ovirt1.localdomain\:_data/cd0018d3-05cd-4667-a5f8-b26dca65a680/images/b87f1fe7-127a-4574-b835-85202f76368a/41fcb56c-7ee0-4575-9366-72ae051444f9 image: /rhev/data-center/mnt/glusterSD/ovirt1.localdomain:_data/cd0018d3-05cd-4667-a5f8-b26dca65a680/images/b87f1fe7-127a-4574-b835-85202f76368a/41fcb56c-7ee0-4575-9366-72ae051444f9 file format: raw virtual size: 20G (21474836480 bytes) disk size: 20G [root@ovirt1 images]# qemu-img info /rhev/data-center/mnt/glusterSD/ovirt1.localdomain\:_data/cd0018d3-05cd-4667-a5f8-b26dca65a680/images/9e1065ed-fbc3-455b-a611-f650d56dadc9/aed4306e-7c45-4cf5-82ee-7bed3c9631ce image: /rhev/data-center/mnt/glusterSD/ovirt1.localdomain:_data/cd0018d3-05cd-4667-a5f8-b26dca65a680/images/9e1065ed-fbc3-455b-a611-f650d56dadc9/aed4306e-7c45-4cf5-82ee-7bed3c9631ce file format: raw virtual size: 20G (21474836480 bytes) disk size: 20G [root@ovirt1 images]# ssh engine "rpm -qa | grep ovirt | sort " root@engine's password: ovirt-ansible-cluster-upgrade-1.1.13-1.el7.noarch ovirt-ansible-disaster-recovery-1.1.4-1.el7.noarch ovirt-ansible-engine-setup-1.1.9-1.el7.noarch ovirt-ansible-hosted-engine-setup-1.0.17-1.el7.noarch ovirt-ansible-image-template-1.1.9-1.el7.noarch ovirt-ansible-infra-1.1.12-1.el7.noarch ovirt-ansible-manageiq-1.1.13-1.el7.noarch ovirt-ansible-repositories-1.1.5-1.el7.noarch ovirt-ansible-roles-1.1.6-1.el7.noarch ovirt-ansible-shutdown-env-1.0.3-1.el7.noarch ovirt-ansible-vm-infra-1.1.14-1.el7.noarch ovirt-cockpit-sso-0.1.1-1.el7.noarch ovirt-engine-4.3.3.6-1.el7.noarch ovirt-engine-api-explorer-0.0.4-1.el7.noarch ovirt-engine-backend-4.3.3.6-1.el7.noarch ovirt-engine-cli-3.6.9.2-1.el7.centos.noarch ovirt-engine-dbscripts-4.3.3.6-1.el7.noarch ovirt-engine-dwh-4.3.0-1.el7.noarch ovirt-engine-dwh-setup-4.3.0-1.el7.noarch ovirt-engine-extension-aaa-jdbc-1.1.10-1.el7.noarch ovirt-engine-extension-aaa-ldap-1.3.9-1.el7.noarch ovirt-engine-extension-aaa-ldap-setup-1.3.9-1.el7.noarch ovirt-engine-extensions-api-impl-4.3.3.6-1.el7.noarch ovirt-engine-metrics-1.3.0.2-1.el7.noarch ovirt-engine-restapi-4.3.3.6-1.el7.noarch ovirt-engine-sdk-python-3.6.9.1-1.el7.noarch ovirt-engine-setup-4.3.3.6-1.el7.noarch ovirt-engine-setup-base-4.3.3.6-1.el7.noarch ovirt-engine-setup-plugin-cinderlib-4.3.3.6-1.el7.noarch ovirt-engine-setup-plugin-ovirt-engine-4.3.3.6-1.el7.noarch ovirt-engine-setup-plugin-ovirt-engine-common-4.3.3.6-1.el7.noarch ovirt-engine-setup-plugin-vmconsole-proxy-helper-4.3.3.6-1.el7.noarch ovirt-engine-setup-plugin-websocket-proxy-4.3.3.6-1.el7.noarch ovirt-engine-tools-4.3.3.6-1.el7.noarch ovirt-engine-tools-backup-4.3.3.6-1.el7.noarch ovirt-engine-ui-extensions-1.0.4-1.el7.noarch ovirt-engine-vmconsole-proxy-helper-4.3.3.6-1.el7.noarch ovirt-engine-webadmin-portal-4.3.3.6-1.el7.noarch ovirt-engine-websocket-proxy-4.3.3.6-1.el7.noarch ovirt-engine-wildfly-15.0.1-1.el7.x86_64 ovirt-engine-wildfly-overlay-15.0.1-1.el7.noarch ovirt-guest-agent-common-1.0.16-1.el7.noarch ovirt-guest-tools-iso-4.3-2.el7.noarch ovirt-host-deploy-common-1.8.0-1.el7.noarch ovirt-host-deploy-java-1.8.0-1.el7.noarch ovirt-imageio-common-1.5.1-0.el7.x86_64 ovirt-imageio-proxy-1.5.1-0.el7.noarch ovirt-imageio-proxy-setup-1.5.1-0.el7.noarch ovirt-iso-uploader-4.3.1-1.el7.noarch ovirt-js-dependencies-1.2.0-3.1.el7.centos.noarch ovirt-provider-ovn-1.2.20-1.el7.noarch ovirt-release43-4.3.3.1-1.el7.noarch ovirt-vmconsole-1.0.7-2.el7.noarch ovirt-vmconsole-proxy-1.0.7-2.el7.noarch ovirt-web-ui-1.5.2-1.el7.noarch python2-ovirt-engine-lib-4.3.3.6-1.el7.noarch python2-ovirt-host-deploy-1.8.0-1.el7.noarch python2-ovirt-setup-lib-1.2.0-1.el7.noarch python-ovirt-engine-sdk4-4.3.1-2.el7.x86_64 Best Regards,Strahil Nikolov В понеделник, 29 април 2019 г., 20:45:57 ч.

Hi, I strongly suspect this is the same problem I’ve reported a few days ago as “New disk creation very slow after upgrade to 4.3.3”, in particular this: In the UI the default is "preallocated" but changing it to thin provision does not make any difference, regardless of this setting, an fallocate process gets started on the SDM host and takes forever to create the pre-allocated image. The observed slowness is just a symptom of always creating a pre-allocated image. From a cursory look at the history, the _default_ in a HC environment is now supposed to be set to “preallocated”. https://github.com/oVirt/ovirt-engine/commit/8b0969cfca241821e6cb5e923a2d... I wonder if this change made it unconditional … Best regards — Steffen
