How To Uncrease Partition Size In Archlinux

After installing Arch Linux on the Raspberry Pi you will more often than not need to expand the disk size to the maximum available size used by SD cards.

And here we testify how to do it:

one. After logging in you view the status of filesystem:

[root@alarmpi ~]# df -h Filesystem      Size  Used Avail Utilise% Mounted on /dev/root       1.7G  444M  1.2G  28% / devtmpfs         83M     0   83M   0% /dev tmpfs           231M     0  231M   0% /dev/shm tmpfs           231M  236K  231M   1% /run tmpfs           231M     0  231M   0% /sys/fs/cgroup tmpfs           231M     0  231M   0% /tmp /dev/mmcblk0p1   90M   24M   67M  27% /boot

2. Using the command fdisk will edit the filesystem /dev/mmcblk0:

[root@alarmpi ~]# fdisk /dev/mmcblk0 Welcome to fdisk (util-linux 2.23.1). Changes will remain in memory simply, until you decide to write them. Be conscientious earlier using the write control.   Control (m for help):

iii. List the information and delete partition 2

Command (m for assistance): p   Deejay /dev/mmcblk0: 7969 MB, 7969177600 bytes, 15564800 sectors Units = sectors of i * 512 = 512 bytes Sector size (logical/concrete): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk characterization type: dos Disk identifier: 0x00057540           Device Kick      Start         Stop      Blocks   Id  System /dev/mmcblk0p1            2048      186367       92160    c  W95 FAT32 (LBA) /dev/mmcblk0p2          186368     3667967     1740800    5  Extended /dev/mmcblk0p5          188416     3667967     1739776   83  Linux   Control (m for help): d Partition number (1,2,5, default 5): ii Sectionalization 2 is deleted   Command (chiliad for help):

4. Create a new extended partition a logical book

Control (m for aid): northward Partitioning type:    p   primary (i principal, 0 extended, 3 costless)    e   extended Select (default p): eastward Division number (ii-4, default 2): two Outset sector (186368-15564799, default 186368): Using default value 186368 Concluding sector, +sectors or +size{G,One thousand,G} (186368-15564799, default 15564799): Using default value 15564799 Partition 2 of blazon Extended and of size 7.3 GiB is set up   Command (m for help): n Partition type:    p   primary (1 chief, ane extended, 2 free)    l   logical (numbered from 5) Select (default p): l Adding logical partition 5 First sector (188416-15564799, default 188416): Using default value 188416 Final sector, +sectors or +size{Thou,M,Thou} (188416-15564799, default 15564799): Using default value 15564799 Sectionalization 5 of blazon Linux and of size vii.3 GiB is prepare   Command (m for help):

5. !! Cheque whether summit block starts in the same place equally the original (kickoff)

Command (thou for help): p   Disk /dev/mmcblk0: 7969 MB, 7969177600 bytes, 15564800 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/concrete): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk characterization type: dos Deejay identifier: 0x00057540           Device Boot      Start         End      Blocks   Id  System /dev/mmcblk0p1            2048      186367       92160    c  W95 FAT32 (LBA) /dev/mmcblk0p2          186368    15564799     7689216    v  Extended /dev/mmcblk0p5          188416    15564799     7688192   83  Linux   Command (one thousand for help):

vi. If it starts once more (in this case on 186368 p2 a 188416 p5) write changes and reboot.

Command (k for help): w The partition table has been altered!   Calling ioctl() to re-read division table.   WARNING: Re-reading the partition table failed with error 16: Device or resource busy. The kernel still uses the old table. The new table will be used at the next reboot or later on you run partprobe(8) or kpartx(viii) Syncing disks. [root@alarmpi ~]# reboot

seven. After booting the organisation we online enlarge root partitions

[root@alarmpi ~]# resize2fs /dev/mmcblk0p5 resize2fs 1.42.viii (20-Jun-2013) Filesystem at /dev/mmcblk0p5 is mounted on /; on-line resizing required old_desc_blocks = 1, new_desc_blocks = ane The filesystem on /dev/mmcblk0p5 is at present 1922048 blocks long.

8. Check and information technology is washed :-)

[root@alarmpi ~]# df -h Filesystem      Size  Used Avail Employ% Mounted on /dev/root       seven.3G  447M  vi.5G   7% / devtmpfs         83M     0   83M   0% /dev tmpfs           231M     0  231M   0% /dev/shm tmpfs           231M  236K  231M   one% /run tmpfs           231M     0  231M   0% /sys/fs/cgroup tmpfs           231M     0  231M   0% /tmp /dev/mmcblk0p1   90M   24M   67M  27% /kick

In this case we accept used 8GB SD bill of fare.
