There are 24x400GB drives, so the total is just above 8TB. After running the following commands: pvcreate --metadatasize 1024 /dev/sdb1 pvcreate --metadatasize 1024 /dev/sdc1 vgcreate -s 128M vg0 /dev/sdb1 /dev/sdc1 lvcreate -n lv0 -L8T vg0 The lvcreate command gobbles up CPU and memory as would be expected, however, I get the following error message: device-mapper device too small for target: /dev/sdb1 device mapper ioctl cmd 9 failed: Invalid argument. could not load device vg0-lv0 failed to activate new LV Am I doing something incorrectly? I've tried with both Fedora Core 3 and Fedora Core 4. Any pointers on how I should continue with this would be greatly appreciated. Kind regards, Devon H. O'Dell
