Dear All,

I try to use our cluster though samba share. Everything work fine, but
I think, we should have -o flock at lustre mount time.

Great, it's work. But when I want to save a file on the share, I get
this on the logs:

I attached the lustre-log.

What could cause this problem? The reason, I wanted to use flock is
there are some softwares, which  cannot save files by various reasons
on the cluster share (for example MS O2K3, Project 2K7).

But as I can see, right now doesn't matter, it is a notepad, or a
Project 2K7.


Cluster's version is 1.6.4.1 and 1.6.0.1 and I tested this with
1.6.4.1 and 1.6.2.


What can I do?


Thank you,

tamas
