Unfortunately I had absolutely same problem, except for that the NAS was worked until last day and on it the weight of the data is stored...
Is it can be possible to make something else except system updating?

=============================
We have a problem with access to shared resources organized by the NAS with Open-e.

In the GUI (maintanance -> recources misc.) writes:
"Warning: no logical Volume!! (lv00)"
And I can't to do something on this interface page...

The system displays the following error.
