не монтируется роздел

в системе два SCSI винта 20 Гбайт и 40 Гбайт.
розбил вот так :

Cleopatra ~ # fdisk -l

Disk /dev/sda: 18.3 GB, 18351959040 bytes
64 heads, 32 sectors/track, 17501 cylinders
Units = cylinders of 2048 * 512 = 1048576 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          96       98288   83  Linux

/dev/sda4            4006       17501    13819904   83  Linux

Disk /dev/sdb: 36.7 GB, 36703918080 bytes
64 heads, 32 sectors/track, 35003 cylinders
Units = cylinders of 2048 * 512 = 1048576 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1       35003    35843056   83  Linux

при загрузке говорит

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

ставил Gentoo 2006.0 из stage-3
когда распакововал стейдж роздел смонтировал нормально... теперь даже вручную говорит mount: /dev/sdb1 already mounted or /var busy
если опять загрузится из лайв СД ручками смонтировать могу.

фстаб такой

Cleopatra ~ # cat /etc/fstab
# <fs>                  <mountpoint>    <type>          <opts>          <dump/pass>

/dev/sda1               /boot           ext2            noatime         1 2
/dev/sda3               /               ext3            rw              0 1
/dev/sda2               none            swap            sw              0 0
/dev/sda4               /usr            ext3            rw              0 2
/dev/sdb1               /var            ext3            rw              2 2

#/dev/cdroms/cdrom0     /mnt/cdrom      iso9660         noauto,ro       0 0
#/dev/fd0               /mnt/floppy     auto            noauto          0 0

proc                    /proc           proc            defaults        0 0
shm                     /dev/shm        tmpfs           nodev,nosuid,noexec     0 0

в чем может быть трабл? ведь роспознало вроде нормально его... да и розделы с первого смонтировало...
