[ENBD] mirror of /dev/hda2 on a second remote machine on the LAN

[Raghavendra Bhat]

List

I   had  installed   the  Debian   GNU/Linux  package   of   enbd  and
kernel-patch-enbd.    Compiled  the   kernel  after   patching,  using
make-kpkg and  everything went off  fine.  Booted into the  new kernel
2.4.20.  I have not added anything to enbd.conf but instead decided to
test my setup.  Inserted the enbd module....

As suggested by Peter, I started the enbd server first, as shown

enbd-server 1111 -t 120 -b 1024 -1 -w 0 -i ragu /dev/hda2

and it echoed  these lines on to the root console  (I have created all
nb* device points inside /dev)

----------<snip>----------------------------------------------------------
enbd-server 990: server (-2) locked /var/state/nbd/server-ragu.client_ips
enbd-server 990: server (-2) unlocked /var/state/nbd/server-ragu.client_ips
enbd-server 990: server (-2) set new signal handlers for master server 990
----------<snip>----------------------------------------------------------


On  another machine,  192.16.1.2 on  the LAN;  I proceeded  and  did a
similar setup but did not start the server process.  Inserted the enbd
module and started the client,

enbd-client 192.168.1.1 1111 -n 4 -b 1024 -i ragu -t 120 -p 5 -d 1 /dev/nda

now this echoes the following on the root console of that machine,

----------<snip>-----------------------------------------------------------
enbd-client 998: <# 421> set_channels client ignores channel multiplier 4 while server name still undefined
enbd-client 998: <# 421> set_channels client ignores channel multiplier 4 while server name still undefined
enbd-client 998: <# 823> cmdline client specified no nbd device! Try /dev/nda. 
enbd-client 998: <#3616> main Cannot open NBD device (null): Success 
----------<snip>-----------------------------------------------------------

The  last two  lines are  indicating  a problem  and I  am just  plain
clueless. Where is it that I am going wrong ?  I want a mirror copy of
the partition /dev/hda2 on the second machine with IP 192.168.1.2

TIA.
