Description AE 2010-12-13 16:10:54 UTC
Version:           unspecified (using KDE 4.5.85) 
OS:                Linux

Hi! In my fstab I have four CIFS shares, marked as 'noauto'. They are displayed in the device notifier widget's list under 'Storage Access'. In terminal, I can mount and unmount as normal user using /bin/mount, /bin/umount.
With device notifier, there are several small problems:

1) If mount.cifs is not set suid-root, mounting as non-root user fails, with command line as well as with device notifier. With device notifier, there is no feedback after a failed mount.

2) I can mount them correctly with device notifier and dolphin opens the volume's root. However, I cannot unmount using device notifier. Unmounting in dolphin works.

3) Once one of the shares is mounted, all four are marked as mounted in device notifier. Again, dolphin displays correctly.

Reproducible: Always

Problem persists with version 4.5.90.
Comment 2 Jacopo De Simoi 2010-12-25 12:39:50 UTC
I'll try to reproduce your setup; I have no CIFS shares so it's quite possible that they require some special attention… stay tuned
Comment 3 AE 2010-12-25 16:54:25 UTC
If you need additional info or have a patch to try against RC1, just say the word... Cheers!

SVN commit 1211298 by jacopods:

Treat remote NFS/CIFS shares as non-removable devices
This is just a hack valid for the 4.6 timeframe, and should *not* be forwardported
to trunk.

Ok, confirmed. The issue is actually in solid-fstab; I'll get in contact with the mantainer soon to fix it. Stay tuned

SVN commit 1211499 by jacopods:

Do the "dbus dance":

all signals such as {setup,teardown}{requested,done} must be routed via the appropriate
dbus interface in order to have them broadcasted to all instances of the same device;
this ensures that mount/unmount notifications work correctly.
