Hi,
I have moved from SD card to SSD following
https://elinux.org/Transfer_system_disk_from_SD_card_to_hard_disk and now have / pointing to /dev/sda1, however, the filesystem size is not increasing even after running
resize2fs
output of mount/dev/sda1 on / type ext4 (rw)
/dev/sda1 on / type ext4 (rw) <- / mounted to SSD i.e. sda1
