mount

[kirill.adw]

всем привет!

Пытаюсь сделать
# mount /dev/sdb1 /var/ftp/
mount: /dev/sdb1 already mounted or /var/ftp/ busy

# umount /var/ftp/
umount: /var/ftp/: not mounted

# umount /dev/sdb1
umount: /dev/sdb1: not mounted

Пробую смонтировать в другой каталог

# mount /dev/sdb1 /var/x/
mount: /dev/sdb1 already mounted or /var/x/ busy

vi /etc/fstab
