Unable to Mount Partition

Getting error while mounting the partition

Error – Already mounted or busy

Answer:
  1. check if there is any process using that device (/dev/sda1). It is often a fsck process which runs automatically on system startup. You can check it quickly e.g. by  ps aux | grep sdb1
  2. If already mounted, unmount using sudo umount -f /dev/sdb
  3. Check mount point mapper details if any old logical volume mount u can remove using dmsetup remove /dev/mapper/[device]
