I restored a backup of a root drive to a new disk on Solaris 8 which contained a fully functioning disksuite 4.2.1 mirror configuration. The backup is from an identical system and OS. I want to install a second identical disk and recover the mirror configuration. The root disk is up but... (2 Replies)

I'm using rsync to back up to a usb key

It worked fine for a long time, and then not so good. Running from the command line there are a lot of complaints about 'can't chgrp ...'. It's formatted to fat32 so I can read it in all kinds of... (0 Replies)
I'm trying to image one hard drive to another using SunOs 5.7. I think I've read all of the forum entries that relate to my questions, but I do not find an effective solution to the problem.

I cannot access or boot from my C drive. I'm running Zorin 9 and the drive is a Samsung SSD. The disk was encrypted on install, and that has not given me any problems before.

Actually this is a Centos 6.x question, but I think it fits here.
I have a client that has a pretty beefy server that will be running all sorts of VMs once I unleash it to the developers. For several reasons, they would like to do a complete clone of the server as is right now, that is with just... (2 Replies)

sd
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 */
CONFIGURATION
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 reread of the SCSI disk partition tables. No parameter is needed.
The SCSI ioctl(2) operations are also supported. If the ioctl(2) parameter is required, and it is NULL, then ioctl(2) will fail
with the error EINVAL.
FILES
/dev/sd[a-h]: the whole device
/dev/sd[a-h][0-8]: individual block partitions
