[ovirt-users] ovirt 4.2.1 pre hosted engine deploy failure

[Michael Seidel]

Hi,

I found the messages at
http://lists.ovirt.org/pipermail/users/2018-January/086631.html in your
archive and am running into a similar/identical issue when trying to
install a hosted engine:

After providing all of the information, the installer does create some
files on the nfs share (plantfiler02:/storage/vmx/ovirt) but eventually
dies with:

[ INFO  ] TASK [Copy configuration files to the right location on host]
[ INFO  ] TASK [Copy configuration archive to storage]
[ ERROR ]  [WARNING]: Failure using method (v2_runner_on_failed) in
callback plugin
[ ERROR ] (<ansible.plugins.callback.1_otopi_json.CallbackModule object
at 0x25c86d0>):
[ ERROR ] 'ascii' codec can't encode character u'\u2018' in position
489: ordinal not in
[ ERROR ] range(128)
[ ERROR ] Failed to execute stage 'Closing up': Failed executing
ansible-playbook
[ INFO  ] Stage: Clean up

The relevant part in the logfile I believe is the following:

I did create vdsm user and kvm user and group on the NFS server and I
succesfully ran the nfs-check.py script from the host where ovirt should
be installed:

# python nfs-check.py plantfiler02:/storage/vmx/ovirt/
Current hostname: hyena.******.de - IP addr 10.216.60.21
Trying to /bin/mount -t nfs plantfiler02:/storage/vmx/ovirt/...
Executing NFS tests..
Removing vdsmTest file..
Status of tests [OK]
Disconnecting from NFS Server..
Done!


The target directory has following permissions:

drwxr-xr-x 3 vdsm      kvm  86 Mar  9 09:12 ovirt


I am aware of the issue
https://bugzilla.redhat.com/show_bug.cgi?id=1533500 but the underlying
problem seems to be the error message issued by dd (as has been
mentioned the earlier posts).


Am I missing the obvious somewhere regarding permissions? Is there a
known solution/workaround to this?

Best,
