Sorry to touch in it again. But I was simply ignored, is this report
erroneous? May I add some information to get some kind of answer about this?
There is other mail list to report this?
Because Im really scared I lost ALL DATA from this volume after this
happened. It was a test volume but I want to put this over real systems.
Any tips.
