Hi, Jorge. I think one possible weak link is the scsi adapter and/or raid device. SL41 has all of the software angles covered (large raw devices; large filesystems; large scsi addresses), but I think there is still a chance that your scsi layer cannot address more than 2 TB per LUN. If the problem is in the adapter, the solution might be as simple as switching to one of the adapters known to support the 64-bit addressing. If the problem is an embedded raid controller, you might be forced to define several <=2TB hardware arrays, and then use a software raid0 or concat to combine these. -Jan On Thu, 18 Aug 2005, Connie Sieh wrote: > Date: Thu, 18 Aug 2005 09:00:34 -0500 (CDT) > From: Connie Sieh <[log in to unmask]> > To: "Jorge Izquierdo (UAM)" <[log in to unmask]> > Cc: [log in to unmask] > Subject: Re: SL 4.0/4.1 x86_64 support for large filesystems > > Jorge, > > On Thu, 18 Aug 2005, Jorge Izquierdo (UAM) wrote: > > > Hi everybody, I'm getting a bit desperate with this subject. > > > > I've updated my SL to version 4.1 and I've obtained the same results as > > with 4.0.
