  1. [Samba] Notification changes sometimes works, sometimes no

    Hi.
    I have compiled samba 3.0.28 and 3.0.30 under both ARM and x86.
    I have enabled inotify into the kernel.
    I use kernel 2.6.20.4 for both ARM and x86.
    I see a strange problem about notification changes. Sometimes
    automatic notify works,
    sometimes not.

    Now I will show who reproduce the error I see.
    I have installed SAMBA on 10.0.0.61.

    *******
    PHASE 1
    *******
    I open an explorer window and I insert "\\10.0.0.61".
    A window with USER and PASSWORD appears.
    I insert user and password, and my share called "RootDisk" apperars.
    A click on "RootDisk", and I can use my share. It works OK, and also the
    notification is OK. I can create files and remove then, and I have the
    automatic update.

    *******
    PHASE 2
    *******
    Now I close my explorer window.
    I open a new explorer windows.
    I enter "\\10.0.0.61".
    I click on "RootDisk".
    Now, If I create or remove files, then notification does NOT works !
    I have to press F5 key.

    *******
    PHASE 3
    *******
    Now I close the explorer window.
    I open a new explorer window.
    I enter "\\10.0.0.61\RootDisk".
    Now I create and remove files, and the notification works OK.

    ------------------------------------------------------------------

    I underline that I exec PHASE1, then PHASE2, then PHASE3 in this order.
    PHASE1 and PHASE3 works OK, PHASE2 does not work OK.

    I have tried to insert some debug messages in source/smbd/notify_inotify.c but
    I have not understood the difference when notification works OK and
    when there is the notification problem.
    Inotify support is OK (I have added debug messages and I see them). I
    think there is something strange in the communication
    client-server.

    I think my smbd.conf is very simple.

    I have tried to add some config option
    -> socket options = TCP_NODELAY
    but this does not solve my problem.

    Is this a known error ? or do I make some error ? or is my config incomplete ?

    Thanks in advance

    Please file a bug at https://bugzilla.samba.org and upload
    your smb.conf and a debug level 10 log of smbd.

    Hi Volker,
    thanks for your fast replay.

    I have the log. It is large.
    zipped is 160KB, unzipped more than 3MB
    Where can I post it ? I don't think the mailing list is the right
    place .... it is too big !

    I already insert the bug in https://bugzilla.samba.org

    Some details :
    CLIENT arch = WIN XP
    SERVER arch = LINUX ARM 2.6.20.4

    I attach
    -smb.conf
    -configure parameter

    Thanks
    Paolo
