[SOLVED] Problem with Partition

[ferdinandum]

Good afternoon,
I'm partitioning a disk of 500GB but not if I'm doing well.

Here are the steps I've done

$this->bbcode_second_pass_code('', '
# /sbin/fdisk /dev/sda1

# Command: p (p = listado de particiones)
# Command: n (n = nueva partición)
# Command: p (p = partición primaria)
# Partition number: 1 (numero de la partición)
# First cylinder: poner el primero que deje
# Last cylinder: +250M (250 Mb)


# Command: n
# Command: p
# Partition number: 2
# First cylinder: default
# Last cylinder: default
# Command: w

# /sbin/mkfs.ext3 /dev/sda1

')

This is the result:
$this->bbcode_second_pass_code('', '
root@alarmpi ~ $ /sbin/fdisk -l

Disk /dev/mmcblk0: 3904 MB, 3904897024 bytes, 7626752 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000c21e5

Device Boot Start End Blocks Id System
/dev/mmcblk0p1 * 2048 194559 96256 c W95 FAT32 (LBA)
/dev/mmcblk0p2 194560 3862527 1833984 83 Linux

Disk /dev/sda: 500.1 GB, 500074283008 bytes, 976707584 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

Device Boot Start End Blocks Id System
/dev/sda1 2048 976707583 488352768 7 HPFS/NTFS/exFAT
')

The first partition I want to be the linux swap and the second for storage

but when I do the following tells me that there is no exist

i dont no what I'm doing wrong
$this->bbcode_second_pass_code('', '
# Command: t
# Command 1 (1=first partition)
# Hex code: 82 (82 = Linux Swap)
')

It rather obviously either: hasn't re-read the partition table, or didn't work at all. Try unplugging & re-plugging the drive.

[pepedog]

Do not do this
/sbin/fdisk  /dev/sda1
Do this
/sbin/fdisk  /dev/sda

[WarheadsSE]

Hah, good catch, I missed that pepedog.

[ferdinandum]

Thx

It was

$this->bbcode_second_pass_code('', '/sbin/fdisk /dev/sda')

[pepedog]

Only noticed because I persistently make this mistake

[ferdinandum]

This is the result:
$this->bbcode_second_pass_code('', '
Device Boot Start End Blocks Id System
/dev/sda1 2048 514047 256000 82 Linux swap / Solaris
/dev/sda2 514048 976707583 488096768 83 Linux
')

And in the /etc/fstab i did:
$this->bbcode_second_pass_code('', '
# <file system> <dir> <type> <options> <dump> <pass>
devpts /dev/pts devpts defaults 0 0
shm /dev/shm tmpfs nodev,nosuid 0 0
/dev/mmcblk0p1 /boot vfat defaults 0 0

/dev/sda2 /media/almacen ext3 defaults 1 2
/dev/sda1 none swap 0 0
')

It's correct?

[Magikarp]

It looks good, but dump for sda2 should be 0. And why didn't you format it ext4?
You should also remove devpts and shm lines since they are not needed anymore.

EDIT: It would be good idea to use UUIDs for idenifying partitions. If you boot with for example usb stick pluged, external hdd might become sdb and not get mounted.

Thx Magilkap, its good but i quite difficult to do this.

I did
$this->bbcode_second_pass_code('', '
root@alarmpi ~ $ swapon -s
root@alarmpi ~ $ swapoff /dev/sda2
swapoff: /dev/sda2: swapoff failed: Invalid argument
')

[pepedog]

Did you
mkswap /dev/sda1
swapon /dev/sda1
