Story of the problems continues. Finally shut everything down, got
storage domains to maintenance and then this happens:
ovirtsdk4.Error: Fault reason is "Operation Failed". Fault detail is
"[Physical device initialization failed. Please check that the device
is empty and accessible by the host.]". HTTP response code is 400.
[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg":
"Fault reason is \"Operation Failed\". Fault detail is \"[Physical
device initialization failed. Please check that the device is empty
and accessible by the host.]\". HTTP response code is 400."}
No amount zeroing device helped.
Next plan: Find out if I can restore backup to standalone server. If
that fails that's the end of oVirt for me. It worked fine for a couple
of years but this update hassle is too much. Should have gone until
the end with 4.3.
Thanks,
Juhani
