Hello today I tried to migrate the hosted engine from our Default
Datacenter (NFS) to our Ceph Datacenter. The deployment worked with the
automatic "hosted-engine --deploy --restore-from-file=backup/file_name"
command. Perfect.
Only thing is: I messed up with the cluster name. The name should be
Luise01 but I entered Luise1. Duh...
Now I want to bring the engine back to the Default Datacenter. Easy thing.
Just repeat the same steps again.
1. Enable global ha maintenenace
2. Stop and disable the engine
3. create the engine backup
4 ... continue with all the steps from chapter 13.1.8 RHEV Docs 4.3 Beta.
Everything looked great. The ansible playbook was running, then asking for
the storage domain. I entered the NFS path. It got registered, but then the
ansible playbook errors out with
[ INFO ] TASK [ovirt.hosted_engine_setup : Add VM]
[ ERROR ] Error: Fault reason is "Operation Failed". Fault detail is
"[Cannot attach Virtual Disk. The target Data Center does not contain the
Virtual Disk.]". HTTP response code is 409.
[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg":
"Fault
reason is \"Operation Failed\". Fault detail is \"[Cannot attach Virtual

response code is 409."}
[ ERROR ] Failed to execute stage 'Closing up': Failed executing

I see that there is a bug report on
https://bugzilla.redhat.com/show_bug.cgi?id=1649424
Any idea how to get around this error ?
It seems barely reproducible: maybe a race condition somewhere.
I know it can look a bit clumsy but I suggest to simply give it another try.
Additionally I now have a HostedEngineLocal (shut off) on that node... How
do I remove it?
engine-cleanup ?
You can even simply destroy that VM with virsh and run again the deployment.
Have to get some sleep.
best regards.
