Re: [Samba] oplocks issue when trying to copy file

2011-12-19 Thread Joschi Brauchle 

I reported the issue here:
https://bugzilla.samba.org/show_bug.cgi?id=8670

Please find level-10 logs and strace there.

Best regards,
Joschi Brauchle

Hi!

More interesting would be a debug level 10 logfile together
with a strace -ttT -o /tmp/smbd.strace -psmbd-pid on
the smbd relevant for the client.

Hello everyone,

I would like to follow up on the thread [Samba] oplocks issue when
trying to copy file, which I found while googling for a problem.

We have the same setup and problem mentioned in that thread:
Our Samba server (version 3.5.12) exports a share that was mounted
via NFS from another machine. We are using SUSE Linux Enterprise and
this setup used to work with kernel oplocks = yes in SLES10, but
not in SLES11SP1.

I did some research and found that the kernel commit
http://kernel.opensuse.org/cgit/kernel/commit/?h=SLE11-SP1id=dd143426eaaadea159c8dd2d3c9ff5e9da94bcfd
mentioned in this thread is included in SLES11SP1 kernel 2.6.32.29.

So I downgraded to SLES11SP1 2.6.32.12 on a test-machine and can
confirm that the problem goes away with kernel oplocks turned on!

As a workaround, one can disable kernel oplocks or use the -o
nolock option when mounting via NFS.

I guess this kernel regression should be reported to Novell. I can
provide the samba-level-10 logfiles for 2.6.32.12 (working) and
2.6.32.29 (not working).

Best regards,
