are you able to recall or verify which version of ovirt-hosted-engine-setup
did you used when you initially created your hosted-engine env?
I suspect that your issue could be somehow related to
https://bugzilla.redhat.com/show_bug.cgi?id=1339306 which have been fixed
which patch http://gerrit.ovirt.org/57906 for new deployment but not for
who deployed before that and than simply upgraded engine rpms over his
working engine VM.
For 4.1 we are thinking at a mechanism to upgrade also engine VM definition
when running engine-setup, currently it's not available.
Probably the best option to fix it right now is something like:
- set global maintenance mode
- manually removing the engine VM from the engine DB (to let the
auto-import procedure trigger again)
- shutdown the engine VM
- copy your /var/run/ovirt-hosted-engine-ha/vm.conf somewhere
- edit it adding the required devices
- start the engine VM with hosted-engine --vm-start --vm-conf=myvm.conf
- wait for the auto-import procedure to kick in and re-import the engine VM
with the additional devices
- exit global maintenance mode
Roy, do you see something simpler to achieve the same result?
