mount

[mitsumoto]

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

народ помогите пожалуйста, примонтировать mount /dev/sdb1 /var/ftp/
знаю что проблема решиться обычным ребутом сервера, но его перезагружать нельзя (((

Определить, какому LABEL соответствует какое устройство поможет blkid.

Попробуйте fsck натравить перед маунтом, если фс не "чистая", маунтить тоже откажется.

PS Можете ещё попробовать монтировать с трассировщиком

strace mount /dev/sdb1 /var/ftp/

Будет видно, в чём затык.

[mitsumoto]

Вот трассировка монтирования...

Устройство занято и всё тут :o

Стоит глянуть, кем занято устройство при помощи команды fuser.
