mountwam bez problem 
listwam bez problem
no kogato pochna da kopiram mashinata 
zaspiwa i si bylwa w syslog-a posledniq red ...

razchetoh se iz google-a i se okazwa che tozi problem
go imat mnogo hora.
do kolkoto shwashtam winownika e server-a a ne client-a
no servera ne logwa nishto
malko tcpdump i se wivda che server-a
ne otgowarq:

13:28:32.792191 angelfire.vega..1056795006 > XXX.nfs: 1472 write [|nfs]
(frag 30482:1480@0+)
13:28:32.792316 angelfire.vega..1073572222 > XXX.nfs: 1472 write [|nfs]
(frag 30483:1480@0+)
13:29:32.792208 angelfire.vega..1056795006 > XXX.nfs: 1472 write [|nfs]
(frag 30484:1480@0+)
13:29:32.792330 angelfire.vega..1073572222 > XXX.nfs: 1472 write [|nfs]
(frag 30485:1480@0+)
13:30:32.792197 angelfire.vega..1056795006 > XXX.nfs: 1472 write [|nfs]
(frag 30486:1480@0+)

towa sa opitite client-a da pishe
no nikakyw reziltat ot server-a

po interesnoto e che ako kopiram malyk file 
nqma problemi (ili pone taka mislq)

q google-a namerih slednoto:

Trond suggested that it might routers who are not passing on UDP
fragments. I checked this: the packets are going through the same
hardware, just on different VLANs. And again: I don't have this
problem on 2.2.17 or earlier.

Changing the route on the server to the other interface does solve the
hang on the client side.

iskam da popitam prosto dali nqkoj e imal takyw problem
i kak go e reshil ako go e... :)

10x in advance :)
