Hi Peter, I'm also running a Dell MD1000 in RAID5 on a CentOS system (4.6), with LVM on ext3. I never came across a 2TB limit or your particular errors... I had one 1.4TB LVM volume which I extended into the 3.6TB of the MD1000, for one large 5TB LVM volume (mounted on root). The only problem I had was getting the driver loaded at boot time (solved with a new initrc). I hope this helps...
