Hi List,


I have a file server which runs samba-3.0.28a. My aim is to share a logical volume ( with XFS filesystem) using SAMBA, NFS and FTP. Since it is a file server I’m very much concerned about file locking. After googling and reading a lot I had set file locking flags in smb.conf 


lock directory = /var/lock/samba

strict locking = no

locking = yes

level2 oplocks = no

kernel oplocks = yes

oplocks = yes


But still I am having lots of problems in file locking. Following conditions are not working as expected


CIFS(linux) --> CIFS(windows)



How ever CIFS(windows) --> CIFS ( windows) locking working as expected.



Can any one suggest best suitable combination file locking parameters for me?


Thanks & Regards,

Anoop P A
