Hi Andrija,
Thanks for the info, your solution works. It was possible to easily replace the IP address with a DNS record. Everything works correctly! :-) For community: virsh secret-undefine UUID Regards, Piotr From: Andrija Panic <andrija.pa...@gmail.com> Sent: Tuesday, September 10, 2019 8:13 PM To: users <users@cloudstack.apache.org>; Piotr Pisz <pi...@piszki.pl> Subject: Re: replace existing rbd pool Piotr, user/secret is not encrypted or in any way related to the MON IPs/FQDN. The problem you have (afaik) is that your ACS is trying/asking libvirt to create a new secret for (what seems to it as a new storage pool, due to now using FQDN - i.e.since you changed it's IP to FQDNS, it needs to again provision a new Ceph storage pool with new FQDN, which also requires a new secret - but the value is the same, thus the problem... I would try to generate yet another ACS user/secret for the same pool - and change both the IP and the user/secret in the DB to the new values - thus KVM will be able to create what seems to be a NEW Ceph pool (using FQDN) and the new user/secret XML. This means, you old VMs will continue to use old IP/user/secret on the old POOL, while newly started VMs will use new FQDN, new user/secret and again the old POOL. The alternative is to put Ceph in the maintennace mode (in ACS), which will stop all VMs, and (should) remove Ceph pool from Libvirt - then change IP to FQDN, and enable the Ceph in ACS - a Ceph storage pool will be added to all your KVM hosts/libvirt - and you are good to go (start VMs). That being, said, make sure to test this in test ENV.

We want to replace a single IP with a round robin dns record, but the information about the user / secret is probably encrypted and after exchanging I get the message: Failed to define the libvirt secret: org.libvirt.LibvirtException: internal error: a secret with UUID fdf75cf1-3587-3d8b0a-5cf5c1b0f1d4 is already defined for use with admin@x.x.x.x:6789/rbd <mailto:admin@x.x.x.x:6789/rbd> Regards, Piotr -- Andrija Panić
