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

It's actually an iSCSI LUN (NetApp filer). I successfully configured (ext3) and mounted it, but when I rebooted, the /dev/sdb1 device/partition is seen by the kernel and it shows up with "fdisk -l".

Nevertheless I get that error. I've tried "umount" and am informed that /blah isn't mounted. I've tried "lsof" and don't find a process that's attached to /blah.

Hi, Maybe this: 1. Remove the entry from /etc/fstab, reboot. 2. Try to mount it manually. If it works, then something's wrong with the iscsi startup.
