I not sure if the disk - sdf is the problem here and need to replace it

  • Is not the error in English? What is the real purpose of the question? – Rui F Ribeiro Jan 13 at 13:09

Yes, disk sdf is reporting errors on multiple blocks. Replace it at the earliest opportunity. You might want to also look into using smartctl to get stats on the disk failures

smartctl -a /dev/sdf
