Hi, When playing with a dual Opteron box with a large RAID5 (6 TB) attached I noticed a couple of very strange things with fdisk. Distro is SL93 on the latest YOU level. When a volume (say, /dev/sdb) is larger than 2 TB fdisk does not allow me to create partitions bigger than 1.2 TB, and it does not allow me to assign the remaining space to more partitions. When the volume is smaller, I can assign the whole volume to a single partition (e.g. 1.4 TB). Maybe 64 Bit LBA is the bad guy. We tried two SATA RAID Adapters: - Areco ARC-1160. This one allows you to create volumes smaller than 2 GB with standard LBA (32 Bit), > 2 TB with 64 Bit LBA, and a mode "For Windows" whatever this means. - 3ware 9500S 8mi. Ths controller does not allow you to create volumes at all, you get always the entire RAID as a volume. Very spartanic if you ask me. What's going on here? TIA -- Workers of the world, arise! You have nothing to lose but your chairs.
