Memperbesar Partisi SDCard di Raspberry Sesuai Kapasitas SDCard

Kalau kita melakukan instalasi secara biasa Ubuntu Mate / Raspberry di SDCard untuk versi Raspberry, kita akan mendapati penggunaan space yang jauh lebih kecil dibanding kapasitas sdcard.

Sebagai contoh, ketika menggunakan Ubuntu Mate dengan ukuran SDcard 16MB hanya digunakan sekita 8 MB saja. Sayang kan.

Berikut cara menggunakan semua space SDCard

1. fdisk: cancel and rewrite the partition 2; write at the end.
2. reboot
3. resize2fs

Berikut Teknisnya ...

#1. fdisk

root@auser-desktop:~# sudo fdisk /dev/mmcblk0

Welcome to fdisk (util-linux 2.25.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.


Command (m for help): p
Disk /dev/mmcblk0: 14,9 GiB, 15931539456 bytes, 31116288 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
Disklabel type: dos
Disk identifier: 0x00000000

/dev/mmcblk0p2      133120 31116287 30983168 14,8G 83 Linux

Command (m for help): d     
Partition number (1,2, default 2): 2

Partition 2 has been deleted.

Command (m for help): n
Partition type
   p   primary (1 primary, 0 extended, 3 free)
   e   extended (container for logical partitions)
Select (default p): p
Partition number (2-4, default 2): 2
First sector (133120-31116287, default 133120):
Last sector, +sectors or +size{K,M,G,T,P} (133120-31116287, default 31116287):

Created a new partition 2 of type 'Linux' and of size 14,8 GiB.

Command (m for help): w
The partition table has been altered.
Calling ioctl() to re-read partition table.
Re-reading the partition table failed.: Device or resource busy

The kernel still uses the old table. The new table will be used at the next reboot or after you run partprobe(8) or kpartx(8).

root@auser-desktop:~# 

#2 Reboot

#3. resize2f

auser@auser-desktop:~$ sudo resize2fs /dev/mmcblk0p2
[sudo] password for auser:
resize2fs 1.42.12 (29-Aug-2014)
The filesystem is already 3872896 (4k) blocks long.  Nothing to do!

auser@auser-desktop:~$ 

Sekarang cek dengan perintah df
Jreeeng, ukuran partisi sdh berubah.
