http://unix.stackexchange.com – i want to partition raw disk image with those following commands #creating the blank image $ dd if=/dev/zero of=example.img bs=1M count=50 #write the partition table $ parted example.img mktable msdos #creating partition but not the file system #creating fat32 primary partition 1 to 15 MB $ parted example.img mkpart p fat32 1 15 #creating ext3 primary partition 16 to end $ parted example.img mkpart p ext3 16 -0 These command doesn't create file system. How could i do that .. i am trying mkfs command in parted but it showing no command found. How could I create file system externally ? Th (HowTos)

Stories similar to partitioning disk image file

First I create a properly aligned partition in a new GPT table using parted by specifying percentages for start and end of the partition:

# parted -a optimal /dev/sdb GNU Parted 2.3 Using /dev/sdb Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) mktable gpt Warning: The existing disk label on /dev/sdb will be destroyed and all data on this disk will be lost.

I want to create a windows accessible partition(FAT16/FAT32). But even the created partition can read under linux. It can not see on Windows.

for the moment i havent free space yet

(parted) mkpart Partition type? primary/extended? primary File system type? [ext2]? ext4 Start? 60G End? 62.9G Warning: You requested a partition from 60.0GB to 62.9GB.

For testing I want to create a mirrored (RAID 1) partition with a size of 1GB on /dev/sdb and /dev/sdc.

I've created two partitions with parted:

mklabel gpt mkpart primary ext4 1 80% mkpart primary ext4 80% -1

after reboot these are properly shown

parted /dev/sdc print Model: easyRAID Q12 (scsi) Disk /dev/sdc: 4999GB Sector size (logical/physical): 2048B/2048B Partition Table: gpt

Number Start End Size File system Name Flags 1 1049kB 3999GB 3999GB primary

I was getting one program for partitioning SD card.I have given that script below:

#!/bin/sh if [ $# -lt 2 ]; then echo "example usage: $0 /dev/sdc \$ANDROID_ROOT" exit 1 fi

DRIVE=$1 ANDROID_ROOT_DIR=$2

sudo umount ${DRIVE}*

sudo dd if=/dev/zero of=$DRIVE bs=1 count=1024 sudo sync sudo parted $DRIVE mklabel gpt sudo parted $DRIVE mkpart boot fat32 1MB 9MB sudo parted $DRIVE mkpart system

LUKS on >2TB disk 1 year 9 weeks ago

I have a 3TB disk which I want to encrypt.

I have just finished building an 8 disk (2TB each disk) raid 6 array + lvm + xfs, which is currently empty.

Each drive was first setup using parted:

Code: parted -a optimal /dev/sdb GNU Parted 2.3 Using /dev/sdb Welcome to GNU Parted!

parted limitations 2 years 21 weeks ago

running RHEL 5.3 64bit, parted does not allow creation of more than 16 partitions (usin GPT partition table), e.g. when attempting to create next (17th) partition I get

(parted) mkpart primary 43GB 44GB Error: Error informing the kernel about modifications to partition /dev/sdb16 -- Invalid argument.
