I see, if you use 4.3 you will have to add the repos manually on the ovirt-engine node and vdsm hosts If you did not enable cinderlib in engine-setup previously you have to do that, yes On Tue, Sep 14, 2021 at 11:43 AM Tommy Sway <sz_cuitao@163.com> wrote:
But my system version is 4.3, so how can I activate it? Do I should install as documented before running engine- Setup? It seems that CiderLib is also given a database to create while running engine-setup，so I guess the setup-config maybe also important.

If it's already enabled there's no need to run it again. I looked at the doc again now, and it's slightly outdated, since 4.4.8 we add the required openstack (victoria) and ceph repos automatically

Thank you very much!
I read the documentation and found out that you are one of the authors of this feature! I guess I asked the right person.
After installed the CinderLib as you mentioned in the second link, do I still need to run engine setup and integrate CinderLib to use Managed Block ?

cinderlib (Managed Block Storage) does not use openstack at all, we have an example of how to add ceph in the feature page[1]
and docs have instructions on how to set it up[2]

You mean to configure ceph in Cinder pages must be connected to real openstack?
Can ceph be connected to a Managed Block page by simply linking to cenderlib files without accessing the actual openstack?
I am very interested in this section, can you send some related guide documents?
Thank you very much!

cinder uses an actual openstack environment setup with cinder, cinderlib does not require it

What's the difference between cender page and Managed Block page ？
If have to connect them through cinderlib，why not put them all under cinder page ？

yes, we support ceph via cinderlib, so in theory any vendor with a storage driver for cinder can work, but we only test ceph
