you said that the disks are deleted although an exception is given but the engine is reporting the delete as failed. I think that I remember a bug reported and fixed on that as well but I can't seem to find it.

I've done some more tests - and it seems quota error is not related to my issue: I tried to remove another disk and this time there were no quota errors in engine.log

What catches my eye in logs is this errors, but maybe that's not the root of case:

in any case this is a bug.
I'm adding Doron to this mail, perhaps this was reported in the past and
already solved in later versions.
if not it should be reported and fixed.

If I'm not mistaken, it looks like this bug:

do you have quota enabled?

Yes, quota in "enforced" mode. But VMs/disks in question belongs to
"unlimited" quota (defined quota policy with no limits on storage/cpu/ram)

Hi,

I've recently encountered a problem with removing disks from iscsi
domain in my test lab - just cant remove any.
Remove operation fails with message "User admin@internal failed to
initiate removing of disk pg-slave1_opt from domain iscsi-store" and
re-elections of SPM. After that - disk is marked as "illegal" in ovirt
webinterface, however, it is _in fact_ removed from storage -
lvdisplay doesn't show it and free space is updated correctly.
And this happens with just about every disk/vm i try to remove.

ovirt 3.2.2-el6
centos 6.4
vdsm-4.10.3-17.el6
lvm2-2.02.98-9.el6

Any tips? logs in attach
