Description Scott Spurrier 2010-08-17 19:38:42 UTC 
Description of problem:

We use NFS mounted home directories located on Network Appliance filers which support snapshotting. The snapshots are kept under a hidden .snapshot directory. If a user traverses into the .snapshot directory under ~/Desktop, the gnome desktop will suddenly display every available snapshot (typically 24 directories for the past 24 hours and 3 or 4 nightly directories). The desktop is treating these directories as if they were removable media just inserted. It's not possible to unmount these or delete them from the Desktop. Logging out and back in doesn't clear them. You have to wait hours for the mounts to time out before they disappear.

How can we prevent the Desktop from displaying these directories? Since they are subdirectories of ~/Desktop/.snapshot, why are they even showing up?


How reproducible:
Always

Steps to Reproduce:
1. open a shell and cd to ~/Desktop on a NetApp nfs home directory with snapshots enabled.
2. cd .snapshot; ls
3. Notice all the snapshot directories on the Desktop

Additional info:

This problem doesn't happen on RHEL5.
Comment 3 RHEL Program Management 2010-08-17 19:58:11 UTC 
This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release.

** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **
Comment 4 Tomáš Bžatek 2010-08-18 08:58:54 UTC 
Could you please attach output of the `mount` and `udisks --dump` commands?
Comment 6 RHEL Program Management 2010-08-18 21:32:49 UTC 
Thank you for your bug report. This issue was evaluated for inclusion
in the current release of Red Hat Enterprise Linux. Unfortunately, we
are unable to address this request in the current release. Because we
are in the final stage of Red Hat Enterprise Linux 6 development, only
significant, release-blocking issues involving serious regressions and
data corruption can be considered.

If you believe this issue meets the release blocking criteria as
defined and communicated to you by your Red Hat Support representative,
please ask your representative to file this issue as a blocker for the
current release. Otherwise, ask that it be evaluated for inclusion in
the next minor release of Red Hat Enterprise Linux.
Comment 7 Tomáš Bžatek 2010-08-25 12:58:47 UTC 
Interesting and also strange enough. I couldn't see any suspicious mounts belonging to snapshots. Usually we show mounts from fstab (filtered by some criteria), abandoned/unowned physical devices, active mounts and GVfs stuff. Do mtab or /proc/mounts show these records?

Can you also attach output of `gvfs-ls -lh computer://` when the extra mounts are shown and do `gvfs-info computer:///<mount_name>` on one of them? Or, is this easily reproducible on a local machine?

gvfs-1.4.3-hide-dot-mounts.patch

After little chat with David yesterday we agreed to hide mounts where the mountpoint path element starts with a dot (i.e. hide /media/.shared and also /media/.subdir/shared).

Glib2 must be patched too along with gvfs.
