Here's some more input on my ongoing saga with smbfs and WfW.
*****************************
1) Brought up WfW 3.11, mounted from 2.1.65, ran 'iozone auto':
Nov 22 10:37:27 cy kernel: smb_newconn: server not locked, count=1
Nov 22 10:37:27 cy kernel: smb_offerconn: server not locked, count=1
Nov 22 10:37:27 cy kernel: smb_offerconn: state valid, pid=221
Nov 22 10:37:35 cy kernel: smb_request_ok: rcls=1, err=18 mapped to 0
Nov 22 10:37:36 cy last message repeated 2 times
Nov 22 10:37:40 cy kernel: smb_proc_open: BENCH/iozone.tmp R/W failed, error=-26, retrying R/O
Nov 22 10:37:40 cy kernel: smb_open: BENCH/iozone.tmp access denied, access=0, wish=1
It failed with "Error writing block 0".
****************************
2) Tried again:
Nov 22 10:38:47 cy kernel: smb_request_ok: rcls=1, err=18 mapped to 0
It ran correctly.
***************************
3) Umounted the smb share from Linux, then remounted and re-ran iozone:
Nov 22 10:39:27 cy kernel: smb_newconn: server not locked, count=1
Nov 22 10:39:27 cy kernel: smb_offerconn: server not locked, count=1
Nov 22 10:39:27 cy kernel: smb_offerconn: state valid, pid=236
Nov 22 10:39:49 cy kernel: smb_request_ok: rcls=1, err=18 mapped to 0
Nov 22 10:39:49 cy last message repeated 2 times
It ran correctly.
**************************
4) Umounted the smb share, shut down and restarted WfW, remounted and
ran 'strace -o /tmp/output iozone auto':
Nov 22 10:42:37 cy kernel: smb_newconn: server not locked, count=1
Nov 22 10:42:37 cy kernel: smb_offerconn: server not locked, count=1
Nov 22 10:42:37 cy kernel: smb_offerconn: state valid, pid=252
Nov 22 10:42:52 cy kernel: smb_proc_open: BENCH/iozone.tmp R/W failed, error=-26, retrying R/O
Nov 22 10:42:52 cy kernel: smb_open: BENCH/iozone.tmp access denied, access=0, wish=1
This was the strace capture:

This appears to be a WfW wart which occurs when writing to the first
newly-created file on the server. Hopefully this information will suggest
a workaround?
