After solving the engine VM part (see dedicated thread) I continued and
follow the steps indicated for the host.
After reboot and exiting maintenance I found the hosted_storage domain in
state "unattached" and not "maintenance" as in another test I have
done
(note that in in that test there were not true data domains configured
apart the hosted_storage...)
I also got some exceptions inside the GUI when going into storage tab on
hosted_storage line. See:
https://drive.google.com/file/d/0BwoPbcrMv8mvYmdQYVM0dkRJaGM/view?usp=sha...
Uncaught exception occurred. Please try reloading the page. Details:
(TypeError) __gwt$exception: <skipped>: c is null
I tried to attach the hosted_storage but then the engine VM went down
I did wait for about 10 minutes and the VM was not restarted.
Is there any reason for ithe environment to "automatically" go back into
maintenance?
Because as soon as I run again the command
hosted-engine --set-maintenance --mode=none
the engine VM was started again.....
Is there any command to see the current state of maintenance
(none/local/global)?
Anyway the hosted_storage domain still is in unattached state...
BTW: even if the host has been updated:
[root@ractor ]# yum update
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
* base: ba.mirror.garr.it
* extras: ba.mirror.garr.it
* ovirt-3.6: ftp.nluug.nl
* ovirt-3.6-epel: epel.besthosting.ua
* updates: ba.mirror.garr.it
No packages marked for update
[root@ractor ]#
Inside the webadmin gui in hosts tab I still see the icon indicating
"update available" for it
And in action items: "a new version is available" message
In software subtab the host is detected as:
