How do I go about troubeshooting this? I'm using RHEL 4 update 6.
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.
I also tried "fsck -t ext3 /dev/sdb1" which worked (so it detects the ext3 file system).
Any other tools to check out? === Al

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.

cat /proc/mounts cat /proc/mounts | grep sdb1
You could possibly have /dev/sdb1 already mounted at some different mount point. If that doesn't help, look for aliases for sdb1 in /dev

Do you have an entry for /dev/sdb1 in /etc/mtab ? If so, try manually removing that line and try the mount again.
