Do you run it from the engine's machine? The host? Elsewhere?
Where is the iso domain?
This sounds to me like a bug, but I didn't check the sources yet.
Please open one. Thanks.
That said, you can simply copy your iso file directly to the correct
directory inside the iso domain, which is:
/path-to-iso-domain/SOME-UUID/images/11111111-1111-1111-1111-111111111111/
Make sure it's readable to vdsm:kvm (36:36).
Best,

I'm running the command from the Engine itself, it seems to be the only box
that has this command available. The ISO domain utilizes the same root
share as the DATA and EXPORT domains which seem to work fine. The structure
looks something like:
server:/nfs-share/ovirt-store/iso-store/UUIDblahblah/images/
server:/nfs-share/ovirt-store/export-store/path/path/path
server:/nfs-share/ovirt-store/data-store/UUIDblahblah/images/
Each of storage-domain was created through the Engine. Perms for each
below, which persists all the way down the tree:
drwxr-xr-x. 3 vdsm kvm 4 Nov 14 19:02 data-store
drwxr-xr-x. 3 vdsm kvm 4 Nov 14 19:04 export-store
drwxr-xr-x. 3 vdsm kvm 4 Nov 14 18:18 hosted-engine
drwxr-xr-x. 3 vdsm kvm 4 Nov 14 19:04 iso-store
If I attempt to mount any of them via NFS from our management network they
work just fine. (moved around, read/write operations)
Copied the ISO I needed directly to it and changed the perms/ownership by
hand which seems to have worked as a short term solution.
I can see why the --iso-domain argument has issues as it is trying to use
the our storage network, which isn't routable from the Engine as it only
has the one network interface. Although that does seem like an oversight.
Seems like this transfer should pass through the SPM and not try to
directly mount the NFS share if the --iso-domain flag is used.
Thanks for the quick response.

Good. Not sure it's that short term - it was suggested several times
here and people seem to use it.

Indeed this is a somewhat complex subject, which is why it was somewhat
neglected so far. There is some work to fix this recently, see e.g.:
https://bugzilla.redhat.com/show_bug.cgi?id=1122970
http://lists.ovirt.org/pipermail/devel/2014-December/thread.html#9481

(yes, two separate discussions this month).

Ok well thanks for the help. Moving it by hand is not a huge deal. I just
assumed that since it was recommended to use the command in the docs that
it was worth mentioning. case closed I guess. unless we want to consider
the NFS error worthy of a bug report?

You mean the attempt to nfs mount the storage directly from the engine?
It has an option to use ssh instead, you can try that too if you feel
curious. See the man page.
If it's something else, I missed it - please give more details.
Of course you can open a bug if you want. I guess it will be low priority
and will probably solved eventually by reimplementing the command line
tool using the work that will be done for the "upload from gui" bug.
Still, detailing your structure/flow will be useful as a test case.

in our case our nas doesn't support scp but that no fault of the the
manager.
I was mentioning more specifically that the --nfs-server method seemed to
throw an error on an undefined attribute 'domaintype' that is not something
that can be supplied in the config file or passed as an argument. the out
put from the the debug is further up in my first email.
you are right though. probably not worth it since the best solution would
be a gui implementation.
thanks again.

Feel free to also open a bz for inclusion in some version earlier than 3.6
(our current master branch).

That's not what I meant - a gui is obviously more comfortable for casual
use, but for batch/scripting etc you want a command line tool. But
hopefully our implementation for the gui uploader will be first in the
rest api, then in the gui. The rest api will be useful also for scripting -
either directly or by reimplementing the current tool with it.
Thanks and best regards,

Excellent. Confirmed, this fixes the bug and fails with a more descriptive
error.
