Controller HA and cloudstack

mpb · January 19, 2025, 4:38am

Hi There, I followed this material “https://linbit.com/drbd-user-guide/linstor-guide-1_0-en/#s-linstor_ha” on a test environment for a multicontroller HA which is working fine. To my understand there should have been a virtual IP to integrate with cloudstack for storage, but I didnt come across any virtual IP during the HA controller config. my question is how to confgure cloudstack in a Linstor multicontroller environment…?

You add the ocf IPaddr2 to the linstor_db.toml start section. like this:

"ocf:heartbeat:IPaddr2 service_ip cidr_netmask=24 ip=10.0.0.99",

Then you can use this service ip in CloudStack

Hi, I have this in the config “/etc/drbd-reactor.d/linstor_db.toml” hope its correct, but its not pinging to that IP, how to test before installing cloudstack

[[promoter]]
id = “linstor_db”
[promoter.resources.linstor_db]
start = [“var-lib-linstor.mount”, “linstor-controller.service”, “ocf:heartbeat:IPaddr2 service_ip cidr_netmask=32 ip=192.168.126.180”,]

on all the host:

root@host1:~# drbd-reactorctl status linstor_db
/etc/drbd-reactor.d/linstor_db.toml:
Promoter: Currently active on node ‘host2’
○ drbd-services@linstor_db.target
× ├─ drbd-promote@linstor_db.service
○ ├─ var-lib-linstor.mount
○ ├─ linstor-controller.service
○ └─ ocf.rs@service_ip_linstor_db.service

any idea

Thanks

This knowledge base article, “Troubleshooting DRBD Reactor Promoter Plugin Services”, can perhaps help you troubleshoot DRBD Reactor promoter managed services that are not starting.

shouldn’t the netmask be 24?

And your output says, it is running on host2?

Changed to /24, but the service IP not working yet…

Hi, I found on the github website for drbd-reactor…can anyone please help…

" OCF agents are expected in /usr/lib/ocf/resource.d/ . Please make sure to check for resource-agents packages provided by your distribution or use the packages provided by LINBIT (customers only)."

I installed from the Ubuntu 22.04 PPA distribution, but so you have to be customer for the virtual IP to work ?

virtualip service is not coming up at all

○ ├─ ocf.rs@db_virtip_linstor_db.service

● └─ linstor-controller.service

My config
vi /etc/drbd-reactor.d/linstor_db.toml
[[promoter]]
id = “linstor_db”
[promoter.resources.linstor_db]
start = [“ocf:heartbeat:IPaddr2 db_virtip ip=192.168.126.180 cidr_netmask=24 iflabel=virtualip”,“var-lib-linstor.mount”,“linstor-controller.service”]

This is all I have in the folder
