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
I did some research and found that the kernel commit
mentioned in this thread is included in SLES11SP1 kernel 188.8.131.52.
So I downgraded to SLES11SP1 184.108.40.206 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 220.127.116.11 (working) and
18.104.22.168 (not working).
