Udev label removes corresponding fdisk, sfdisk or lsvdev entry
I'm curious about the behavior where any udev labeled device causes that corresponding listing to disappear from fdisk, sfdisk, or in the case of RDAC, lsvdev.
I have seen this on both EMC clariion and Sun Storagetek/Engenio 6540 arrays.
We use RHEL5.1 and udev to create persistent labels for Oracle devices.
I'm comfortable that we can always reference the /dev/ocr* or /dev/vot* devices, I'm just looking for how to explain this behavior. Is there some mechanism under the hood causing it? Is it so someone doesn't do things with those fdisk listed devices and inadvertently wipe out udev labeled ones?
installed fedora core 5 on a pc with USB and some usual things. in boot up it is stopped at "Starting udev:". Its harddisk light is busy. is it reconfiguring the kernel?. what do to solve this problem?. (0 Replies)

Hi guys,
I want to write a script to automate partitioning for some project that I'm working on. I tried using fdisk but it was too painful... so, turned to sfdisk but now I'm getting strange results...or at least I think so.

Hi,
Using fdisk I created a partition of 15.7 GB. I entered +15700M
Using sfdisk there is a heading called blocks and there is a number which is approximatly 400 BM less. When I mount the partition and use df -l the 1K block column displays only 15GB!
I need to understand these numbers if... (2 Replies)

fdisk
CFDISK(8) GNU fdisk Manual CFDISK(8)NAME
GNU fdisk, lfdisk, gfdisk - manipulate partition tables on a hard drive
SYNOPSIS
fdisk [options] [device]
DESCRIPTION
fdisk is a disk partition manipulation program, which allows you to create, destroy, resize, move and copy partitions on a hard drive using
a menu-driven interface. It is useful for organising the disk space on a new drive, reorganising an old drive, creating space for new oper-
ating systems, and copying data to new hard disks. For a list of the supported partition types, see the --list-partition-types option
below.
It comes in two variants, gfdisk and lfdisk. Lfdisk aims to resemble Linux fdisk 2.12, while gfdisk supports more advanced disk operations,
like resizing the filesystem, moving and copying partitions. When starting fdisk, the default is to run gfdisk.
OPTIONS -h, --help
displays a help message.
-v, --version
displays the program's version.
-L, --linux-fdisk
turns on Linux fdisk compatibility mode. This is the same as running lfdisk.
-G, --gnu-fdisk
turns off Linux fdisk compatibility mode.
-i, --interactive
where necessary, prompts for user intervention.
-p, --script
never prompts for user intervention.
-l, --list
lists the partition table on the specified device and exits. If there is no device specified, lists the partition tables on all
detected devices.
-r, --raw-list
displays a hex dump of the partition table of the disk, similar to the way Linux fdisk displays the raw data in the partition table.
-u, --sector-units
use sectors, instead of cylinders for a default unit.
-s, --size=DEVICE
prints the size of the partition on DEVICE is printed on the standard output.
-t, --list-partition-types
displays a list of supported partition types and features.
The following options are available only to lfdisk.
-b, --sector-size=SIZE
Specify the sector size of the disk. Valid values are 512, 1024 and 2048. Should be used only on older kernels, which don't guess
the correct sector size.
-C, --cylinders=CYLINDERS
Specify the number of cylinders of the disk. Currently does nothing, it is left for Linux fdisk compatibility.
-H, --heads=HEADS
Specify the number of heads of the disk. Reasonable values are 255 or 16.
-S, --sectors=SECTORS
Specify the number of sectors per track. A reasonable value is 63.
BUGS
Before editing a BSD disklabel, the partition with the disklabel should already exist on the disk and be detected by the OS. If you have
created a BSD-type partition, you need to write the changes to the disk. If fdisk fails to notify the OS about the changes in partition ta-
ble, you need to restart your computer. As fdisk tries to guess the device holding the BSD disklabel, it might fail to edit it at all, even
if the OS has detected it. In this case you are adviced to simply open the device with fdisk directly. It is possible that it doesn't work
on some operating systems.
Getting the size of a partition with -s might fail, if fdisk fails to guess the disk device, for the same reasons as with the previous bug.
