Hello,
We've been seeing a problem with Samba server 3.0.33-0.17 handling lock
files for Microsoft Powerpoint 2007. The problem is observed in both
Windows XP and Windows Vista.
If a user opens an existing file, smbstatus looks like this:
10781 11021 DENY_WRITE 0x2019f RDWR NONE
/usr/test/dssg test1234ecg2.pptx Fri Oct 23 17:21:52 2009
10517 11021 DENY_NONE 0x100001 RDONLY NONE
/usr/test/dssg . Fri Oct 23 17:06:08 2009
10517 11021 DENY_NONE 0x100001 RDONLY NONE
/usr/test/dssg . Fri Oct 23 17:06:08 2009
10781 11021 DENY_NONE 0x100001 RDONLY NONE
/usr/test/dssg . Fri Oct 23 17:16:19 2009
10781 11021 DENY_NONE 0x100001 RDONLY NONE
/usr/test/dssg . Fri Oct 23 17:16:19 2009
10781 11021 DENY_WRITE 0x3019f RDWR EXCLUSIVE+BATCH
/usr/test/dssg ~$test1234ecg2.pptx Fri Oct 23 17:21:52 2009
Notice, there are both test1234ecg2.pptx and ~$test1234ecg2.pptx.
If the user saves, once in awhile (some as often as 1 in 4, some more like
1 in 20 saves), they'll be told that the file is read-only and get offered
to save as a new file name. When this happens, smbstatus only shows the
~$test1234ecg2.pptx version of the file.
The only way out of this is to exit Powerpoint (after saving to a new
name). Well, also you can remove the ~ version of the file from the UNIX
side, but Windows won't let you do that.
We have tried the following locking options (one at a time) in smb.conf
without any of them helping:
reset on zero vc = yes
strict locking = yes
locking = yes
lock spin time = 10000
It may not be relevant, but I'll add that the Samba servers sit on top of
an OpenAFS share. I say it may not be relevant because I made a local
share and got the same results (shown above), ruling out OpenAFS.
Any advice would be appreciated.
Thank you,
Chris
