Hello,

I expect to use enbd for a raid over local net .

The point is that i make test for all that could suit. Unfortunatly, i ran iozone on enbd-2.4.28 and i got on the server side :

nbd-server  1416: newproto Not enough magic in packet. Breaking off.
nbd-server  1416: slavesighandler server (0) activates slave sighandler for signal 15
nbd-server  1416: server (0) sighandler terminates slave 1416 safely
nbd-server  1415: server (-1) relaunches child after SIGCHLD 
nbd-server  1415: server (-1) slave pid 1416 is down, launching new
nbd-server  1415: server (-1) launched slave pid 1430

The server still ran but the client is just out, hard reboot is necessary.

Both ran 2.4.18 kernel under a RedHat-7.2 , the shared device was 35Go in reiserfs (problem also on ext2).
The number ofchannel doesn't change anything. I didn't put any special option for both client and serv .

I didn't find out what was going on .. 

But i ran an other test and crashed the client again : 
	tar -xzf linux-2.4.18.tar.gz &
	cd linux.two && make bzImage -j 10

Can anyone can help me ? I'll be sorry to put aboard enbd ;)

Is that error because of a lack of cpu ? the point is that iozone don't take so much cpu (it take most time waiting after enbd :) ..

Note : the final usage is for a data filesystem for apache & mysql server .
