That change would have to have happened in Nautilus, since the "external
helpers" feature is something done by the "umount" utility, which
redirects the umount requests to a wrapper (helper), but, before,
removing the uhelper flag from the umount requested.
I'm marking this as "won't fix" because the request was done to
ocfs2-tools and it is pretty old. If you still want to pursue this, I
would recommend opening a new bug targeting Nautilus and udisk utilities
and it will probably be considered a "wishlist" if not implemented by
upstream until today.

Title:
mount.ocfs2 doesn't accept mount option "uhelper=udisks"
Status in ocfs2-tools package in Ubuntu:
Won't Fix
Bug description:
Scenario:
3-node Ubuntu AoE*/OCFS2 Cluster on Ubuntu Server sharing disks with
Ubuntu Desktops
Node 1: Oneiric ubuntu-server amd64 with disk shared using AoE and formatted
and clustered
with OCFS2.
Node 2: Oneiric mint-desktop i386
Node 3: Oneiric ubuntu-desktop amd64
Background:
1. Initially implemented AOE to share disks in node 1 (SAN) formatted
XFS
2. Needed to access FS on disks from more than one Ubuntu desktop
client
3. Implemented OCFS2 cluster and formatted one disk (label "Backup")
in node 1 with OCFS2 to test
Problem:
4. Mounting the disk using Nautilus fails with the following error thrown by
Nautilus:
Unable to mount Backup
Error mounting: mount exited with exit code 1: mount.ocfs2: Invalid argument
while mounting /dev/etherd/e2.0p1 on /media/Backup_. Check 'dmesg' for more
information on this error.
dmesg includes the following:
Jan 6 02:06:52 anthracite kernel: [ 8672.067816]
(mount.ocfs2,27208,1):ocfs2_parse_options:1512 ERROR: Unrecognized mount option
"uhelper=udisks" or missing value
Jan 6 02:06:52 anthracite kernel: [ 8672.067824]
(mount.ocfs2,27208,1):ocfs2_fill_super:1233 ERROR: status = -22
As I understand it the uhelper=udisks mount option relates to the disk
showing up in the "Devices" section of Nautilus.
Further:
5. Nautilus mounts the AoE shared XFS devices without error, even on
multiple devices simultaneously, posing risk to FS integrity
(intentional AoE design)
6. Creating a mount point and mounting the disk (AoE shared OCFS2
"Backup") using the mount command works fine and it still shows up in
the "Devices" section of Nautilus:
# mount -L "Backup" /media/Backup/
Synposis:
7. It would thus appear that mount.ocfs2 does not support this mount
option. This is understandable given that OCFS2 is used heavily in
server-only environments and not in sharing for use by Linux desktop
machines.
8. However, such use cases will surely increase and it should be
trivial to add support for this mount option.
Thanks very much.
