I don't use a dedicated metadata network switch but a HP 8200zl. This 
switch is used only for my xsan lab. 2 vlan are configurated: one about 
public tcp/ip network, one about metadata tcp/ip network. I'll check 
connections. 

 On all my xsan nodes i have this log in /var/log/system. [...]

Well your MDC simply looses the connection to the Volume. It could be
metadata OR it could be FC network. As told earlier, Xsan is really
complicated and you should check all the connections and settings. Even
order of network connections on MDC and clients matter. [...]

I note your link and i'll use it. But i don't understand why you are 
thinking the problem is with fc network and not the metadata tcp/ip network. 

I'm using brocade b300 and xyratex storage. They are out of matrix. But 
unfortunately, i didn't choice the hardware. [...]

Are your Fibre Channel switch and FC cards on MDC and clients configured
correctly? What FC switch you have? Make sure it is configured according
http://support.apple.com/kb/TA24251 Also what type of storage you are using?
Xserve RAID? Promise? 3rd party? [...]

created by the touch command. 
But the system is still having some troubles.

public one 
the metadata dns works almost like a shadow government: some services  
need to resolve addresses on it just in case they are needed.

By "dustbin" you mean Trash folder? If yes, then take a look at the
following documentation:

Basically, you run a DNS server on the public VLAN with both entries  
for public and metadata IPs. For instance, according to "Apple  
Training Series Xsan 2 Administration: A Guide to Designing,  
Deploying, and Maintaining Xsan" by Robert Kite Ph.D. [...]

Well, i configured a zone in the dns about the metadata nerwork. 
Then, i destroyed the entire san. I created again a san and a volume. 
I mounted the new volume on a client and 2 mdc. 
I made a copy of an iso file from local hard drive to san. 
I made a copy from san to local hard drive. [...]

I had crappy performance and weird hangs when the MDCs didn't have  
forward/reverse DNS on the private metadata network. Some people don't  
seem to get it, though.

I have dns configured for mdc on the data network, but not on the 
metadata network. Is it necessary to configure a dns on metadata network ? This email sent to email@hidden

Hello the list,  
Last week, i configured a fresh installed xsan with 2 mdc and 2 clients. 
Friday all was running well. From my clients i was able to access 
central storage and to copy big files on it. This morning, i tried to 
connect to a client with ARD. [...]
