Thin client's tmpfs still mounted when external device unable to mount

[Michael Blinn]

Binary package hint: ltspfs

Description: Ubuntu 8.04.1
Release: 8.04

I carry an ntfs USB stick. When the device is not cleanly unmounted on Windows, it won't mount correctly as a local device on an LTSP client.

Steps to reproduce:

1) Uncleanly unmount from a windows machine (pull the stick without stopping the device)
   a: On a full, fat standalone Hardy box, the device won't mount with the message that the device wasn't unmounted correctly from Windows

2) Plug into a thin client
   a: The device mounts on the desktop, the device name is shown correctly, but I believe it's actually the mountpoint not the device.
   b: The device filesystem size is the same as the client's tmpfs (109MB), instead of the correct 16GB
   c: No files show up
   d: You _can_ copy files to the mountpoint and believe you're copying to the external device. These files persist across removal/insertion of the external device.

3) Pull the device, go back to windows, insert, and then cleanly unmount by stopping the device.
4) Plug into a thin client
   a: The correct original external filesystem will mount with none of the files you copied to the tmpfs mount point.

Gadi says: We should actually send a signal to remove the ltspfs mount if the mount to the client fails

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.

Fix was in for both Jaunty and now Karmic. Marking as closed.
