hi every body
I set the partition size to 20 GB to install Arch but now i want too increase partation
its fdisk -l

[root@skyboy ~]# fdisk -l
Disk /dev/sda: 465.76 GiB, 500107862016 bytes, 976773168 sectors
Disk model: ST500LM012 HN-M5

i create new partition with fdisk with linux system type but i dont see partition in my Dolphin file manager

[root@skyboy ~]# fdisk /dev/sda

Welcome to fdisk (util-linux 2.36).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.


Command (m for help): n
Partition number (2,7-128, default 2): 
First sector (4096-976773134, default 4096): 
Last sector, +/-sectors or +/-size{K,M,G,T,P} (4096-315598847, default 315598847): +100G

Created a new partition 2 of type 'Linux filesystem' and of size 100 GiB.

Command (m for help): w
The partition table has been altered.
Syncing disks.

and after that

[root@skyboy ~]# fdisk -l

/dev/sda6  650569728 692512767  41943040    20G Linux filesystem

Re: [SOLVED] Add Partition Or Resize Partition

I see where you created a partition, but, I don't see where you put a filesystem on it.

Re: [SOLVED] Add Partition Or Resize Partition

a separate partition is fine, but you have to make a filesystem, mount it somewhere, then think about how to use it. the size of the original 20G partition would not change.

it seems like you could grow the partition you already have

parted /dev/sda unit mib print free

if there is free space after sda6, with parted you can use 'resizepart' to grow it, then follow with resize2fs (if it's ext4 filesystem on sda6)

thanks for your attention
i set partition on ext4 :

root@skyboy ~]# mkfs.ext4 /dev/sda2
mke2fs 1.45.6 (20-Mar-2020)
Creating filesystem with 26214400 4k blocks and 6553600 inodes

and partition successfully shown
but i cant do anything like:
i cant create folder,paste or save anything in that partition
how can i solve that?
and this is lsblk -l:

[root@skyboy ~]# lsblk -l
NAME MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda    8:0    0 465.8G  0 disk

Re: [SOLVED] Add Partition Or Resize Partition

It's an ext4 partition so the permissions reside on the filesystem. If you intend this to be a logical extension of your /home chown the directory to your user/group after mounting.

See this example of the same case we have here

I did not understand what to do
i do this:

[root@skyboy ~]# chown user/group /dev/sda2
chown: invalid user: ‘user/group’
[root@skyboy ~]# chown user /dev/sda2      
chown: invalid user: ‘user’
[root@skyboy ~]# chown usr /dev/sda2
chown: invalid user: ‘usr’
[root@skyboy ~]# chown group /dev/sda2
chown: invalid user: ‘group’

Re: [SOLVED] Add Partition Or Resize Partition

Not the device, the directory of the mounted partition (i.e. /run/media/amirsky/dbd17d43-1796-410d-95c0-20 ) . And user/group should be your own local user and the primary group of that same user . Read the entire linked article if you aren't aware of these basics.

[root@skyboy ~]# chown usr /dev/sda2
chown: invalid user: ‘usr’
[root@skyboy ~]# chown group /dev/sda2
chown: invalid user: ‘group’

You have entered the example text. Instead of filling in the required parameters with YOUR actual values.

Instead of

 # chown user/group /dev/sda2 

You should do

 # chown -R skyboy:skyboy /run/media/amirsky/dbd17d43-1796-410d-95c0-20 

That will grant ownership of the newly created filesystem on your partition. I personally would create a dedicated mountpoint for it rather than the auto-generated one.
For example:

# mkdir /mnt/partition2
# mount /dev/sda2 /mnt/partition2
# chown -R skyboy:skyboy /mnt/partition2

Then update /etc/fstab to mount upon boot time.
