Appendix C. Partitioning for Ubuntu The partitions on each SCSI disk are represented by appending a decimal number to the disk name: sda1 and sda2 represent the first and second partitions of the first SCSI disk drive in your system. Here is a real-life example. Let’s assume you have a system with 2 SCSI disks, one at SCSI address 2 and the other at SCSI address 4. The first disk (at address 2) is then named sda , and the second sdb . If the sda drive has 3 partitions on it, these will be named sda1 , sda2 , and sda3 . The same applies to the sdb disk and its partitions. Note that if you have two SCSI host bus adapters (i.e., controllers), the order of the drives can get confusing. The best solution in this case is to watch the boot messages, assuming you know the drive models and/or capacities. Several varieties of partitioning programs have been adapted by Debian and Ubuntu developers to work on various types of hard disks and computer architectures. Following is a list of the program(s) applicable for your architecture. Recommended partitioning tool in Ubuntu. This Swiss army knife can also resize partitions, create filesystems and assign them to the mountpoints. The original Linux disk partitioner, good for gurus. Be careful if you have existing FreeBSD partitions on your machine. The installation kernels include support for these partitions, but the way that fdisk represents them (or not) can make the device names differ. See the Linux+FreeBSD HOWTO (http://www.tldp.org/HOWTO/Linux+FreeBSD-2.html). A simple-to-use, full-screen disk partitioner for the rest of us. Note that cfdisk doesn’t understand FreeBSD partitions at all, and, again, device names may differ as a result. One of these programs will be run by default when you select Partition disks (or similar). It may be possible to use a different partitioning tool from the command line on VT2, but this is not recom- mended. cfdisk fdisk partman C.5.
