Dear All,
old snapsahots seem to be the problem. In fact domain DATA_FC running in
3.5 had some
lvm snapshot volume. Before deactivate DATA_FC I didin't remove this
snapshots so when
I attach this volume to new ovirt 4.2 and import all vm at the same time
I also import
all snapshots but now How I can remove them ? Throught ovirt web
interface the remove
tasks running are still hang. Are there any other methods ?
Thank to following this case.
Best Regads
Enrico
