I have a venerable but rock solid server running SuSE 10, acting as a webserver, running a relatively few, but significant, websites. The machine has multiple disks ranging from a nearly decade old 80 gig IDE which is the OS disk to a 500GB SATA. Recently I tried to upgrade by adding a 3TB SATA, however SuSE 10's fdisk doesn't recognise it - you can see an error appear when it tries to read that disk. I'm guessing the disk size (or one of the block / cluster counts related to it) is beyond the range of what it can handle.
Long term the machine will be replaced with an all-new server, but in the mean time I've decided to install the 3TB disk in my Windows 7 main home machine and install a smaller new SATA in the server. I already know it will recognise a 500GB disk, but am wondering what the maximum size limit for this OS is? I can get 1TB for only a tenner more than a 500GB, or a 2TB for not a lot more.
Does anyone know what the limits for different OS versions are, or is there any way to easily determine them, both on SuSE and other OSs? Googling seems to return lots of hits about file size limits, or installing SuSE on disks, but not the actual limit a given version will recognise.
