Thanks for the response Victor. It is certainly still relevant in the sense that I am hoping to recover the data (although I've been informed the odds are strongly against me)
My understanding is that Nexenta has been backporting ZFS code changes post 134. I suppose that it could be an error they somehow introduced or perhaps I've found a unique codepath that is also relevant pre-134 as well. Earlier today I was able to send some zdb dump information to Cindy which hopefully will shed some light on the situation (I would be happy to send to you as well) -brian On Tue, Aug 17, 2010 at 10:37 AM, Victor Latushkin <victor.latush...@sun.com > wrote: > Hi Brian, > > is it still relevant? > > > On 02.08.10 21:07, Brian Merrell wrote: > >> Cindy, >> >> Thanks for the quick response.
