Hey! So by design your deployment should be fault-tolerant in case you are using keepalived or anything like that for VIP failovers. So you should be able to safely move blades between chassis. The only thing to remember about, which might cause some effect - is memcached, as it can not be set in any HA mode. What makes things worse, is that memcached clients might be waiting for connection timeout when connection is not refused by remote host, which might happen during host shutdown - where it does not accept connections anymore, but also still reachable. You can check on more details here: https://docs.openstack.org/openstack-ansible-memcached_server/latest/alterna... But in general it should be really fine. пн, 9 сент. 2024 г. в 12:32, Ram Ram <ram.ramb2412@gmail.com>:
Hi All
We are currently running 3 control nodes with LXC containers deployed using openstack-ansible release ussuri and need to move 1 control node on HP blade from one chasis to another chasis.
Is there any recommended way/procedure to do that? can we directly move the HP blade from one chasis to another? or we need to install new control node and decommission the older one?
Regards Rambo
