title: How to increase available filesystem size in /dev/root in Linux Centos 7.7 (AltArch)?
body: <p>I am running a fresh installation of CentOS 7.7. on my Raspberry Pi 3 and unfortunatly I am running out of size when installing yum packages:</p>
  
  <pre><code>[root@centos7 ~]# df -h
  Filesystem      Size  Used Avail Use% Mounted on
  /dev/root       1.4G  1.3G  104M  93% /
  devtmpfs        459M     0  459M   0% /dev
  tmpfs           464M     0  464M   0% /dev/shm
  tmpfs           464M   12M  452M   3% /run
  tmpfs           464M     0  464M   0% /sys/fs/cgroup
  /dev/mmcblk0p1  286M   57M  230M  20% /boot
  tmpfs            93M     0   93M   0% /run/user/0
  
  </code></pre>
  
  <p>The OS is installed on a 16gb SD card, so in principle I should have more than enough space:</p>
  
  <pre><code>        Device Boot      Start         End      Blocks   Id  System
  /dev/mmcblk0p1   *        8192      593919      292864    c  W95 FAT32 (LBA)
  /dev/mmcblk0p2          593920     1593343      499712   82  Linux swap / Solaris
  /dev/mmcblk0p3         1593344     4524031     1465344   83  Linux
  </code></pre>
  
  <p>I figured that I should be able to increase the size of the file system with <code>growpart</code> or <code>resize2fs</code> but I am not sure how to do this exactly and I don't want to break anything. What would be the best way to do this? Thanks!</p>
