NB, the changes for issue #5664 can't be added to the NexentaStor 3.x branch. Look for them in the next major release. For new installations, you can add the changes, though. -- richard > > > > -- > Edmund White > ewwh...@mac.com > > > > > On 1/31/12 7:25 PM, "Ragnar Sundblad" <ra...@csc.kth.se> wrote: > >> >> Just to follow up on this, in case there are others interested: >> >> The D2700s seems to work quite ok for us.
