I have Samba 4.0.9 installed under Ubuntu 12.04. It's configured as
a domain member, with a Windows 2008R2 server being the DC. All
workstations are running Windows 7. One of my users is reporting
problems in the following scenario:
1) She creates a folder in one of the Samba shares, and places a
number of documents there.
2) She closes all open documents and closes Windows Explorer
3) Another user on another workstation subsequently renames the
folder as part of the work flow process to indicate it has been
reviewed.
4) The original user then navigates to where the renamed folder
should be and cannot find it, either under the original name or the
new name. Refreshing doesn't help.
5) After a period of time, typically 3-5 minutes but in one case
around 30 minutes, the folder reappears under the new name.
The window of time between steps 2 and 4 is typically fairly small,
as in an hour or less. The problem is intermittent. In the
30-minute case I was able to get on to my own Win7 workstation and
look at the network share, and I saw the folder under the new name.
I then checked with the user and she reported she still couldn't see
it after a refresh, though it appeared shortly (minutes) thereafter.
As diagnostic steps, I've asked the user to try a) logging off; b)
rebooting; but we don't have results of those tests yet.
I considered that this might be related to bug 10174
<https://bugzilla.samba.org/show_bug.cgi?id=10174>, but the original
user is making sure she doesn't have any files or folders open
before the rename occurs.
No, that isn't a related issue. 10174 is a correctness
issue that I'm not sure affects any real application
(although of course you never know with Windows apps. :-).
1) Is this a known issue?
2) Is anyone else experiencing this?
3) Does anyone have any fixes or workarounds?
It's not known to the developers. It looks like a
failure of change notify, but you'd have to drill
down much deeper with wireshark traces to look
into it.
Jeremy.
I have received a suggestion to check whether this might be related to a
mis-configured off-line synchronization (mobsync.exe) on the
workstation, which I will check the next time I have access to the
machine. Assuming I don't find anything there, should I open a
(unconfirmed) bug on this so that if others experience it they can
confirm it?
