I believe the canonical way of creating larger partitions is with "parted" but I can't say I've ever needed it. Will.
Hi, Is it possible to create one raid volume of 3.3 TB (9550SX-8lp X WD5000YS - 8nos) and create a file system with ext3? (CentOs4.3 64bit) The maximum I am getting is 1.24tb and fdisk returns no more space available. But when I say fdisk /dev/sda it list full size of 3.3 TB. But I can not create partitions more than 1.24TB. Any idea? Thanks Rajeev -------------- next part -------------- An HTML attachment was scrubbed...

Also, since its been ref'd to - 3ware provides its own means of supporting large volume blocks - carving. -- Karanbir Singh : http://www.karan.org/ : 2522219 at icq
