iscsi home directory

    I setup an iscsi connection to a newly minted Debian server. Everything work perfectly except when I reboot the server I get the 'Error of Concern' as shown below. The server hangs trying to umount the iscsi device when it is rebooted. Is there something I missed, that must be done because its the /home directory? Has anyone experienced this and found a solution?

    I understand that it is notifying me that that directory is busy. But that doesn't really help, especially on reboot.

    # cat /etc/debian_version 
    # uname -a
    Linux hoist 3.2.0-4-amd64 #1 SMP Debian 3.2.51-1 x86_64 GNU/Linux
    # cat /etc/fstab
    /dev/sdb1       /home        ext4    defaults,auto,_netdev 0 0
    # df -h
    /dev/sdb1               345G  195M  327G   1% /home

    I found the solution:

    I grabbed the uuid:

    # ls -l /dev/disk/by-uuid
    I replaced /dev/sdb1 with the uuid in /etc/fstab and rebooted the server, all is well. :)
