Hi Sven and Wido,
I am facing the same issue with my ACSv4.17. I added my RBD Primary Storage
with Single RADOS monitor IP, Now I want to change it to a round-robin DNS
following are my SoP please correct me if I am wrong.
*1. Change in MySQL database: *There are two tables in the cloud database
called storage_pool and storage_pool_view I will update both of them to
my round-robin DNS.
The _view table is a SQL view. You only need to change the storage_pool
table.
*2. Apply the Impact to Hosts:* One by one host restart to reload Libvirt
and the CloudStack agent to the right XML loaded.
Correct. A reboot is the easiest way.
Wido
Yours sincerely,
Nazmul Parvej

Hi,
The easiest way is to reboot your hosts one by one. This will reload
Libvirt and the CloudStack agent and will make sure you have the right
XML loaded.

Hello everyone,
i caught myself beeing stupid.
While deploying my cluster, I’ve decided to use my mon1.ceph to be the
main RBD Host which leads now to the problem, that a restart of mon1
will be hell.
In despite, i changed the host to a round-robin dns (changed by sql ),
which is the suggested method of the documentation and thought all new
Instances will be deployed with this new host from the database.
But no , still uses the mon1.ceph while deploying new instances (checked
with virsh dumpxml on my hosts), instead of the new set host, mons.ceph
which round-robins through all my mons.
Restart of Cloudstack-management did not help.
Is there anyone who could give me an hint where this rbd hosts might be
hardcoded in the cloudstack-config ?
Best regards,
Sven
