Hi
I'm sure it's not a kernel issue:
S4 DC, s3fs file server (s3fs on the DC), kernel 3.4.6 -> Freezes
S4 DC, 3.6.3 file server, kernel 3.2.0 -> works fine
S4 DC, 3.6.7 file server, kernel 3.4.6, -> works fine
Summary: with a separate Samba 3 file server, the same kernel which
gives freezes under s3fs, works correctly.
Compare apple and apple, are you using the same configuration in 3.6.7
than the one in s3fs (that is generated by Samba AD DC), most probably not.
Can you try two tracks:
1) try to make your samba 3.6.7 config looks like the one of s3fs,
please note that some defaults have changed in s3fs like vfs_objects
that force the use of acl_xattr, also you have to pay attention if there
is folder/files in the share that you serve that are owned by
users/group of the domain in both cases as you might in one case kick
winbindd calls for each and every sid that you have and the other case
you won't.
2) try to use a newer kernel with current s3fs to see if it resolves the
problem.

Hi
2) seems easier so I installed the 3.6.0 kernel on the client.
there are still long periods where the session freezes. Samba outputs this:
/usr/local/samba/sbin/smbd: Oplock break failed for file
home/steve2/.cache/openbox/openbox.log -- replying anyway
Here is the trace:

Re 1)
-Removing acl_xattr makes no difference.
-All users who access the share are domain users belonging to the Domain
Users group.
-To compare apples I would need to sync sysvol to the S3 fileserver and
leave just the global section in smb.conf on the DC. Yes?
-Will s3fs be able to work better serving cifs at a later date? Maybe
this part of it has not been addressed yet.
- Perhaps at the moment the best way to do this is to have a S3 VM on
the DC to do the file and print serving.
Cheers and thanks for your help,
Steve
