So I have had it the piwh for a while running pihole never had any problems until recently got a memory issue. I have used the clean and autoremove and gained 28% but of a 32gb SD card it's showing 6.5gb available for overall use. I have been into the config menu as read somewhere else about expanding to use the full memory card but I get the message below about not being able to? Any ideas much appreciated. Thanks
/dev/mmcblk0p2 is not the last partition. Don't know how to expand
The expand option in Raspberry Pi OS only works on standard 2 partition images.
You have obviously done something else, but not elaborated.
It appears you may have used NOOBS (which wastes 1.3GB).
Depending on what is on the card it may be possible to expand manually but the best option is to do a fresh install.
The cards are auto expanded on the first boot of them, they will then reboot and give you the chance to setup the system. Use the sudo fdisk -l command to find the partition sizes.
