[Health-dev] resizing partition for Raspi

[Edgar_]

Dear all,

on my Raspi I have a 31,3 GB SD-card which is just a liitle bit too 
small for the 32 GB image of 
https://en.opensuse.org/GNUHealth_on_openSUSE at 
http://www.axxite.com/gnuhealth38-Leap15.3-XFCE-raspi4-20210917.img.xz.

Therefore I resized the image from there to 7,52 GB (of which 6,97 GiB 
are used) and installed it then on my 31.3 GB SD-card. But this 
partition is too small now to make openSUSE updates. 20.86 GiB are 
unpartitioned now.

My partitions are now:

Device                        Size             F        Enc            
Type     Label                Mount point

/dev/mmcblk1               29,12 GiB                                     
    Disk

mmcblk1p1                    64 MiB                                     
FAT partition      EFI                /boot/efi

mmcblk1p2                    500 MiB                                     
    Swap partition       Swap               swap

mmcblk1p3             7,52 GiB ext4 partition                 ROOT    
            /

mmcblk1p4                    191 MiB                                     
ext4 partition


With Yast2 partitioner I wanted to resize this 7,52 GiB to the maximum 
or at least 27 GiB, but the partitioner says that max size is 7,52 GiB. 
Is there any other way to increase the size of mmcblk1p3 to 27 GiB?

Thank you very much for your help!

All the best
