4.5.4 with Ceph only storage

Hey ... A long story short ... I have an existing Red Hat Virt / Gluster hyperconverged solution that I am moving away from. I have an existing Ceph cluster that I primarily use for OpenStack and a small requirement for S3 via RGW. I'm planning to build a new oVirt 4.5.4 cluster on RHEL9 using Ceph for all storage requirements. I've read many online articles on oVirt and Ceph, and they all seem to use the Ceph iSCSI gateway, which is now in maintenance, so I'm not real keen to commit to iSCSI. So my question is, IS there any reason I cannot use CephFS for both hosted-engine and as a data storage domain? I'm currently running Ceph Pacific FWIW. Cheers

Hi, Why not use rbd? This is interface for virtual machines k Sent from my iPhone

Hi, I have installed a ceph-cluster on Debian 12 and ovirt cluster on centos stream 9. I want to use ceph storage cluster with ovirt cluster but how? Its a test environment and i want to use it in production (running ovirt with traditional iscsi SAN so i want to replace it by ceph storage) after successful integration in testing environment? But How? Many Thanks. Ankit

Hi, You can use Cinderlib to achieve this [1] [1] https://www.ovirt.org/develop/release-management/features/storage/cinderlib-... k Sent from my iPhone

AFAIK, only this blog post is a documentation [1] Cheers, k [1] https://blogs.ovirt.org/2021/07/using-ceph-only-storage-for-ovirt-datacenter...

Hi k, Thanks, I have tried to follow this https://www.ovirt.org/develop/release-management/features/storage/cinderlib-... for installing package's part and all were already available in latest ovirt version 4.5 which i am using and i enabled "engine-config -s ManagedBlockDomainSupported=true" but still not ManagedBlockStroage option appeared in domain creation window. i have installed ovirt-engine4.5 with 1 host and ceph-cluster with 2 Mon and 3 OSD's and trying to use ceph storage for ovirt-cluster. On Engine: $ yum install -y centos-release-openstack-yoga $ yum-config-manager --enable openstack-yoda $ yum install -y openstack-cinder python-pip $ pip install cinderlib On all the hosts: (Vdsm needs to be restarted after installing the packages) $ yum install -y centos-release-openstack-yoga $ yum-config-manager --enable openstack-yoga $ yum install -y python2-os-brick For Ceph backend, the following package is needed in the Engine and in all the hosts: $ yum install -y ceph-common Also, for Ceph backend, a keyring file and ceph.conf file is needed in the Engine. Enable Managed Block Domain in Engine Managed Block Domain is not enabled by default in the Engine. In order to enable it, run the following command and restart the Engine: $ engine-config -s ManagedBlockDomainSupported=true systemctl restart ovirt-engine i have copied /etc/ceph* from mon node to ovirt-engine with ovirt owner permission. Please advise what more i can do to fix this? i am following this https://www.ovirt.org/develop/release-management/features/storage/cinderlib-... ManyThanks, Ankit

The feature page is very old and was written for the very first preview in 4.3. Managed block storage is enabled by default in 4.5. Which datacenter version are you using? On Fri, Mar 1, 2024 at 9:43 AM ankit--- via Users <users@ovirt.org> wrote:

Hi Benny, datacenter version is 4.7. so, what i can to integrate ceph-storage-cluster with Ovirt-4.5 version or the latest version? Many Thanks. AS

it should work on both. you can make sure it's enabled with: $ engine-config -g ManagedBlockDomainSupported I am not sure what is the problem in the UI, you can try checking the console (F12) if there's any problems, and also try creating it with the REST API to try and isolate the problem On Mon, Mar 4, 2024 at 9:31 AM ankit--- via Users <users@ovirt.org> wrote:
