Hi @RajaRuling, thank you for the report. I will see what I can do

[PierreKieffer]

Hi @RajaRuling Can you give me the specifications of the environment you are running on? Which Raspberry? Which OS? 32 or 64 bit? Thks

[RajaRuling]

Hi PierreKieffer/pitop,

Raspberry pi 4b model

Raspian lite 64 bit OS

I was able to fix this myself in cloned copy of git code 23rd line of disk.go file. It is working now correctly after rebuilding and running.

/pitop/pkg/disk/disk.go 23: cmd := "df -h | grep ^\/"

Thanks
