After much banging of heads on walls, I am throwing in the towel and asking the experts ;-) ... To cut a long story short: Is it possible to make a 3TB disk work properly in Linux? Our "disk" is 12x300GB in RAID5 (with 1 hot-spare) on a 3ware 9500-S12, so it's actually 2.7TiB ish. It's also /dev/sda - i.e., the one and only disk in the system. Problems are arising due to the 32-bit-ness of normal partition tables. I can use parted to make a 2.7TB partition (sda4), and /proc/partitions looks fine until a reboot, whereupon the top bits are lost and the big partition looks like a 700GB partition instead of a 2.7TB one; this is a bad thing ;-) I've had my hopes raised by GPT, but after more reading it appears this doesn't work on vanilla x86 PCs. Tips gratefully received. Neil PS: not on-list; I'll be reading the real-time archivers, but CCs of any replies would be appreciated. ___________________________________________________________ ALL-NEW Yahoo!
