Hi,
I just tested with changed configuration. I put
DATASTORE_LOCATION=/real_path_to_datastores and I don't see any problems
with images (references counting and in memory name cache) for the moment.
Do symlinks in virtualisation hosts to datastores location could lead to
that ? I saw that in very old messages in users@lists.opennebula.org.
There are no text about symlinks in opennebula datastore documentation.
Regards, Rolandas Naujikas
P.S. My previous layout was (-> - means symlink):
~oneadmin/var/datastores/100 -> /lustre/one/datastores/100
~oneadmin/var/datastores/101 -> /lustre/one/datastores/101
in hosts and frontend.
New layout is:
~oneadmin/var/datastores -> /lustre/one/datastores
DATASTORE_LOCATION=/lustre/one/datastores
where /lustre/one/datastores is real location of files.

Hi Rolandas,
I've tried to reproduce the bug following your steps, but there must be
something else that is triggering it.
These are the exact commands I have executed, could you please check if
I missed something?

Hi,
I see that bug http://dev.opennebula.org/__issues/1087
<http://dev.opennebula.org/issues/1087> reappeared in
3.8.3. The sequence to repeat is:
1) create an image as save from VM (as an user in oneadmin group);
2) change owner to oneadmin;
3) delete image;
4) repeat (1) and (2) will fail saying "[ImageChown] USER [0]
already
owns IMAGE [N] with NAME XXX", where N - is id of already
deleted image.
Restart of one solves temporary problem.
Also I saw several times that images were in use by nonexistent VM.
onedb fsck will complain and correct that.
At least I can confirm it with cancel action on VM.
