Yes, we had trouble with 2 TB WD disks (I think I sent email to
gridpp-storage list about our experience)
We use 2TB WD Green disks in storage pool and we don't use RAID
controllers. We have SW RAID-5.
The problem is solved now, the disks are working OK on SL5 (so we have
one pool on sl5 and other DPM nodes on sl4). The disks didn't show stable
behaviour on SL4 and we were afraid to have one pool on sl5 .
We bought new storage pool with 2 TB Seagate Barracuda XT disks
because they are faster and have other good features.
