hi,
I'm trying to format a new USB flash drive and I get this:
==> mount | grep sdh
==> mkfs.vfat /dev/sdh1
mkfs.fat 4.1 (2017-01-24)
mkfs.vfat: /dev/sdh1 contains a mounted filesystem.
==> mkfs /dev/sdh1
works
any explanation?
/sbin/mkfs calls a different binary, /sbin/mkfs.ext2.
Different utility does different checks.
of course, but how do you explain that one of them think that it is mounted?
As /dev/sdh1 was in /etc/mtab, it seems that mkfs.vfat uses mtab, and not
mkfs.ext2!
rather strange,isn't it?
