[cinder] How extend volume if cinder-volume host down
Hello guys. Every volume was managed by a specified host. When this host was down or removed. How Can I extend this volume which was managed by this host? I would like to know if we have a solution for this case? Nguyen Huu Khoi
Hello. After google then I understand we need cinder active active. Nguyen Huu Khoi On Sun, Jul 21, 2024 at 9:41 PM Nguyễn Hữu Khôi <nguyenhuukhoinw@gmail.com> wrote:

Greeting, Cinder-volume host-group may help you this case , all cinder-volume service will expose same service hostname instead of cinder node’s hostname, you should check reference best practice of tripleO deployment for cinder-volume e.g. https://access.redhat.com/solutions/3524681 Thanks & Best Regards Sang Tran Quoc (Mr.) FPT Smart Cloud FPT Tower, 10 Pham Van Bach Str., Cau Giay Dist., Ha Noi, Viet Nam E: sangtq8@fpt.com<mailto:sangtq8@fpt.com> T: 0962949843 W: https://fptcloud.com<https://fptcloud.com/> | https://fpt.ai<https://fpt.ai/> From: Nguyễn Hữu Khôi <nguyenhuukhoinw@gmail.com> Sent: Monday, July 22, 2024 11:12 AM To: OpenStack Discuss <openstack-discuss@lists.openstack.org> Subject: Re: [cinder] How extend volume if cinder-volume host down Hello.

Hello. I just summary for who looking this information likes me My problem can be addressed via cinder active-active. It will work if a cinder driver supports it. This is an example for CEPH and Koll-Ansible as Openstack Deployment tool. /etc/kolla/config/cinder.conf [DEFAULT] cluster = ceph /etc/kolla/globals.yml enable_redis: "yes" https://opendev.org/openstack/kolla-ansible/commit/d72500c6ff6c378e044c381ed... cinder-manage update_host from @Tobias Urdin <tobias.urdin@binero.com> will be helpful if we change cinder-volume service to another host when we want to replace or change storage nodes.
