I want to skip the first cylinder (first 1 MB infact) while I partition my disk using fdisk as it is required that the disk partition to be used (for Oracle RAC Installation) must skip the first 1Mb to avoid overwriting the disk VTOC. The way I am using is:
Code:
Command (m for help): n
Command action
e extended
p primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-1305, default 1):
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-1305, default 1305):
Using default value 1305
Command (m for help): p
Disk /dev/sdb: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sdb1 1 1305 10482381 83 Linux
Command (m for help): w
The partition table has been altered!
Can anyone please guide me how to skip first 1 MB?
Hi All,

Anyone know how to go about skipping the initial disk sync of a newly created drbd resource?
I'm creating brand new 30gb partitions and would like to skip the entire initial sync, I've read this is possible but I cannot seem to find the instructions to do it.

Hi,
The disks of my servers are getting full and I need to move the /export/home partition on to a new set of disks. I already have 2 mirrored disks and have added 2 more and mirrored them after creating the filesystem on them.

disktab(4) Kernel Interfaces Manual disktab(4)NAME
disktab - Disk description file
SYNOPSIS
#include <sys/disklabel.h>
DESCRIPTION
The disktab database describes disk geometries and disk partition characteristics. It is used to initialize the disk label on the disk.
The format is patterned after the termcap terminal database. Entries in a disktab file consist of a number of : (colon) separated fields.
The first entry for each disk gives the names which are known for the disk, separated by | (vertical bar) characters. The last name given
should be a long name fully identifying the disk.
The following list indicates the normal values stored for each disk entry: Type Description str Type of disk (for example, removable, win-
chester) str Type of controller (for example, SMD, ESDI, floppy) num Number of sectors per track num Number of tracks per cylinder
num Total number of cylinders on the disk num Number of sectors per cylinder, nc*nt default num Number of sectors per unit, sc*nc
default num Sector size in bytes, DEV_BSIZE default bool Controller supports bad144-style bad sector forwarding num Rotation speed,
rpm, default 3600 num Sector skew per track, default 0 num Sector skew per cylinder, default 0 num Headswitch time, usec, default 0
num One-cylinder seek time, usec, default 0 num Sector interleave (n:1), default 1 num Drive-type-dependent parameters num Boot block
size, default BBSIZE num Superblock size, default SBSIZE num Block size for partition `a' (bytes) num Block size for partition `d'
(bytes) num Block size for partition `e' (bytes) num Block size for partition `f' (bytes) num Block size for partition `g' (bytes)
num Block size for partition `h' (bytes) num Fragment size for partition `a' (bytes) num Fragment size for partition `d' (bytes)
num Fragment size for partition `e' (bytes) num Fragment size for partition `f' (bytes) num Fragment size for partition `g' (bytes)
num Fragment size for partition `h' (bytes) num Offset of partition `a' in sectors num Offset of partition `b' in sectors num Offset of
partition `c' in sectors num Offset of partition `d' in sectors num Offset of partition `e' in sectors num Offset of partition `f' in
sectors num Offset of partition `g' in sectors num Offset of partition `h' in sectors num Size of partition `a' in sectors num Size of
partition `b' in sectors num Size of partition `c' in sectors num Size of partition `d' in sectors num Size of partition `e' in sectors
num Size of partition `f' in sectors num Size of partition `g' in sectors num Size of partition `h' in sectors str Partition type of
partition `a' (4.2BSD file system, swap, etc.) str Partition type of partition `b' str Partition type of partition `c' str Parti-
tion type of partition `d' str Partition type of partition `e' str Partition type of partition `f' str Partition type of partition `g'
str Partition type of partition `h'
