I believe this is handled by the /usr/bin/x2goumount_session perl
script. You might add some debugging to see where it is breaking. I
believe the general process is something like:
x2goumount_session first gets the display for the session in the format
|50| and then a list of mounts for the session in the format:
127.0.0.1 | /tmp/spool_simple1/simple1-50-1267649844_stDKDE_dp24
It next dumps a copy of /etc/mtab into an array.
It then loops through the list of mounts.
Within that loop, it loops through the contents of /etc/mtab to see if
there is an sshfs mount which matches the mount listed in the database.
If it finds a match, it stores the remote device (e.g.,
jsulli...@127.0.0.1:/home/jsullivan/) for the sshfs in a variable named
remote and then breaks out of the inner loop. It then attempts to umount
the mount point retrieved from the database. If it fails, it generates
an error message to the user and continues with the next item in the
outer loop.
Whether or not it found anything in mtab, as long as it did not error
when trying to unmount, it tries to clean up any artifacts from the
session. It deletes the device icons from the user's Desktop directory.
These devices have the format of a modification of the remote variable
stored above ("/" replaced with "_") followed by any of (sshfs-disk),
(sshfs-removable), or (sshfs-cdrom). It then calls sudo x2gopgwrapper
deletemount passing it the session name and the mount point which
deletes the entry from the mounts database table.

Gerry Mike, I might have found a way to reproduce what you saw. If you Reconnect to a Terminated session that had a mounted share it will start a new session but there is a ghost mount in the new session from the previous terminated session. This didn't happen on a suspended session only after I terminated a session then clicked on Reconnect.

Re: [X2go-dev] BUG: when sharing local folders ~/media symlinks not as expected
2. When suspending an x2go session the local shared directory gets unmounted properly on the server, but the desktop link (GNOME) remains on the desktop. After having resumed a session the desktop link is still there but it is invalid. I have to remove it manually, to get rid of it. neither is it possible to reconnect the same local folder via sshfs. However, it is possible to share another local folder via the x2go client. Reproduce: o login to x2go server that runs GNOME (this might not be GNOME specific) o share a local folder manually via x2goclient (e.g. ~/test) o local folder appears in x2go session (desktop icon) o disconnect from the session (suspend) o close x2goclient o start x2goclient again o resume former session o -> desktop icon still there, but invalid!!! o share formerly shared folder again (~/test) o check success with the mount command (mountpoint does not appear...) o -> sharing the same local folder again seems to fail!!! o share another local folder (e.g. ~/test2) o sharing another local folder works for me... Can anyone confirm on this? For the wishlist: the server commands that run in the background should produce at least some debug information in /var/log/syslog... (this is also for terminal server security: the admin of a system should have the possibility to see which user mounts local shares to the server!!!)
