I have a Pi installed on a Syno iSCSI target using Berryboot.
I started with 15 GB partition, but I now need more space.
I resized the Syno target to 25 GB.
I resized the /dev/sda2 of the Pi to 25 GB
I am stuck when trying to resize2fs, I get
resize2fs: Device or resource busy while trying to open /dev/sda
Couldn't find valid filesystem superblock.
Some more info:

My / partition is at 90%, that’s the one I need more space on.
I don’t know how to put it at 25 GB – perhaps there is something else done by Berryboot ?
