In case of embedded devices, where /etc/ is mounted as 'read-only'.
We donot have the /etc/mtab file. So, checking if the device is already
mounted from this file is not sufficient.
Try to read /proc/mounts in case of failure from /etc/mtab.
Issue logs:
/dev/sdb4 /mnt vfat rw,relatime,fmask=0022,dmask=0022,codepage=cp437,
iocharset=ascii,errors=remount-ro 0 0
Here device - sb4 is already mounted.
But, when trying to format using mkfs.f2fs
