Hi
I am testing the possibility of migrating from nfs to cifs to serve our
Linux clients.
Currently we mount the samba shares, e.g. the home directory, using nfs.
The test setup is that instead of:
mount -t nfs hh1:/home2 /home2 -osec=rw,krb5
I changed to:
mount -t cifs //hh1/home2 /home2 -osec=rw,sec=krb5,multiuser
This works fine for console logins, but is very slow (unusable) for
graphical logins to either LXDE or XFCE.
The login sometimes works:

But then as soon as we open the file manager (or do anything else) it
freezes for as long as 5 minutes, before it makes another cifs request
and comes alive for a while:
Terminating connection - 'wbsrv_call_loop: tstream_read_pdu_blob_recv()
- NT_STATUS_CONNECTION_DISCONNECTED'
single_terminate: reason[wbsrv_call_loop: tstream_read_pdu_blob_recv() -
NT_STATUS_CONNECTION_DISCONNECTED]

2012-10-19T09:55:48
It is then OK for a few minutes more until it freezes again until the
next cifs request etc etc. . .
This sometimes occurs in the samba log but with different files each time:
usr/local/samba/sbin/smbd: Oplock break failed for file
home/steve3/.cache/openbox/openbox.log -- replying anyway
Here is the test smb.conf:
# Global parameters
[global]
workgroup = MARINA
realm = hh3.site
netbios name = HH1
server role = active directory domain controller
dns forwarder = 192.168.1.1
idmap_ldb:use rfc2307 = Yes
unix extensions = Yes
panic action = /home/steve/samba-master/selftest/gdb_backtrace %d
[netlogon]
path = /usr/local/samba/var/locks/sysvol/hh3.site/scripts
read only = No
[sysvol]
path = /usr/local/samba/var/locks/sysvol

[home2]
path = /home2
read only = No
Here is the wireshark of a login and a 'cifs freeze'.

Please note that this works fine for the same user and data with both
nfs3 and nfs4.
I think you probably want send this sort of thing to
[email protected] (cc'ed here), and not to me directly.
Sorry, I'll join the list.
What kernel is the client running here?
3.4.6-2.10-desktop
Thanks,
Steve
