The Samba-Bugzilla – Bug 3254
windows client hang when browsing a freebsd samba share which is on a nfs fs
Last modified: 2005-11-17 06:52:02 UTC
When I have upgraded my system to FreeBSD 6 Stable, I found windows client have
hanged when it browsed a share which is a nfs mount fs. However, FreeBSD 5.4
Stable does not have this kind of problem with the same environment. On the
other hand, there is no any problem when I access files on nfs fs in console. In
addition, I have reinstalled all samba related/depended freebsd ports by
"portupgrade -cCuvfrR samba". There is no any nfs related error in system log files.
PS: Samba server is in a freebsd jail but I found it did not affect the result.
(samba running outside also has this problem)
When I browse other shares (not on nfs) on the samba server, there is no any

Samba uses fcntl locks calls on files being accessed. These are expected to work
correctly, even on a remote mounted filesystem. It seems as though there may be
a problem with fcntl locks on either the nfs client or server to cause an
accessing process to hang.
To verify Jeremy's assumption you might try to set 'posix locking = no' in the
share definition. If this helps you still need to look into the locking problem.
When I set 'posix locking = no', the file share works fine.
I think Jeremy is right. Maybe there is a problem in file locking.

Eric, probably best to follow up with the FreeBSD NFS client
maintainers. Closing out this bug.
