I have a disk image file created for use with the Linux version of the QEMU emulator. It's partitioned. I opened it with fdisk and the partitions show up with some extra messages about physical/logical endings:
I noticed that the filename of the image file becomes "knoppix.img1" for the first partition and "knoppix.img2" for the second partition. So... is there a way to mount this outside of QEMU? I tried appending the 1 and 2 to the filename but I just get a "no such directory or file" message. Any ideas? Or am I just sunk?
I've got a RedHat 9 box with LVM support in a 2.4.22 kernel. What I would like to do is take a set of empty files created with 'dd' and concatenate them into a volume group. I've done a good deal of googling, and it seems that this is something that can be done. But when I try to use 'pvcreate'... (3 Replies)
I have a bunch of 4 mm DDS tapes that have two partitions. I read them on my HP-UX 10.20 box by referencing the device files /dev/rmt/0m (partition 0) and /dev/rmt/0mp (partition 1). Unfortunately, my HP-UX box was lightning struck last week so now I'm trying to read these tapes using Unix Services... (2 Replies)

I wanted to know how to find un-partitioned space in a Red Hat Linux server. I tried using fdisk but does not seem to be a user friendly output.
I hope, my question is clear.
Please revert with the reply to my query.

SD(4) Linux Programmer's Manual SD(4)NAME
sd - Driver for SCSI Disk Drives
SYNOPSIS
#include <linux/hdreg.h> /* for HDIO_GETGEO */ #include <linux/fs.h> /* for BLKGETSIZE and BLKRRPART */
CONFIG
The block device name has the following form: sdlp, where l is a letter denoting the physical drive, and p is a number denoting the parti-
tion on that physical drive. Often, the partition number, p, will be left off when the device corresponds to the whole drive.
SCSI disks have a major device number of 8, and a minor device number of the form (16 * drive_number) + partition_number, where drive_num-
ber is the number of the physical drive in order of detection, and partition_number is as follows:
partition 0 is the whole drive
partitions 1-4 are the DOS "primary" partitions
partitions 5-8 are the DOS "extended" (or "logical") partitions
For example, /dev/sda will have major 8, minor 0, and will refer to all of the first SCSI drive in the system; and /dev/sdb3 will have
major 8, minor 19, and will refer to the third DOS "primary" partition on the second SCSI drive in the system.
At this time, only block devices are provided. Raw devices have not yet been implemented.
DESCRIPTION
The following ioctls are provided:
HDIO_GETGEO
Returns the BIOS disk parameters in the following structure:
struct hd_geometry {
unsigned char heads;
unsigned char sectors;
unsigned short cylinders;
unsigned long start;
};
A pointer to this structure is passed as the ioctl(2) parameter.
The information returned in the parameter is the disk geometry of the drive as understood by DOS! This geometry is not the physical
geometry of the drive. It is used when constructing the drive's partition table, however, and is needed for convenient operation of
fdisk(1), efdisk(1), and lilo(1). If the geometry information is not available, zero will be returned for all of the parameters.
BLKGETSIZE
Returns the device size in sectors. The ioctl(2) parameter should be a pointer to a long.
BLKRRPART
Forces a re-read of the SCSI disk partition tables. No parameter is needed.
The scsi(4) ioctls are also supported. If the ioctl(2) parameter is required, and it is NULL, then ioctl() will return -EINVAL.
FILES
/dev/sd[a-h]: the whole device
/dev/sd[a-h][0-8]: individual block partitions
