True, but it is simpler than that. Partitions are not needed in general unless one needs to create a separate task space on a single drive volume. If one has no swap space, then it is entirely possible to run a Linux system with no partitions at all. The file system can be created on a raw disk, and as long as the MBR is good and the boot loader can read the file system, you're good. Note I don't genrally recommend running without a swap space, and going to extra trouble just to prevent partitioning is not very productive, but there is no reason to partition a drive if it is not necessary, whether the "drive" is a single physical disk or an array. > The filesystem still needs a partition/volume but that can created > either by partitioning /dev/mdX *or* creating a logical volume in LVM. It doesn't need a partition, just a block device. That device can be a partition on a disk, a whole disk, or an array. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
