Title:
  Cannot mount partition on iSCSI LUN

Status in open-iscsi package in Ubuntu:
  Invalid

Bug description:
  Distro: Jaunty
  Package: open-iscsi-2.0.870.1-0ubuntu3
  Iscsi target: openfiler
  Expected outcome: mount succeeds
  Actual outcome: mount fails
  Details:

  I am able to log in to my iSCSI LUN using iscsiadm, but when I try to
  mount the partition I get an error.  This used to work on Intrepid,
  and the same commands currently work when run from a CentOS 5.2 or
  Debian Lenny host.  The commands I am running are:

  root at galois:~# iscsiadm -m node -p 10.80.224.21:3260,1 -T iqn.2006-01.com.openfiler:alexz2 -l
  Logging in to [iface: default, target: iqn.2006-01.com.openfiler:alexz2, portal: 10.80.224.21,3260]
  Login to [iface: default, target: iqn.2006-01.com.openfiler:alexz2, portal: 10.80.224.21,3260]: successful
  root at galois:~# mount /dev/disk/by-path/ip-10.80.224.21\:3260-iscsi-iqn.2006-01.com.openfiler\:alexz2-lun-0-part1 /mnt
  mount: /dev/sdg1 already mounted or /mnt busy

  I think the "already mounted or /mnt busy" message is a red-herring as
  I am able to mount other filesystems on /mnt with no problems.

  The kernel messages all look okay:
