[ENBD] Doubled requests

[Arne Wiebalck]

The new version has problems to detect the size of the device (not only
for my device, but also for other devices such as disk partitions). Is
that anything to worry about?

e004:/home/wiebalck/nbd # /tmp/enbd-server 5000 /dev/hda8
enbd-server  6733: <#3392> main server: Could not find size of exported
block device: Success
enbd-server  6733: server: assuming very large number for size and hoping.


Later the server complains about:

file  6766: <#1237> opfile unknown mode 108!
enbd-server  6766: <#1403> do_srv_read errored request!
enbd-server  6766: <#1461> newproto net errored on packet. Breaking off.


And the client's opinion to that is:

enbd-client 11617: <#1419> newproto kernel errored 4 times when we asked
for a new req: No such device
enbd-client 11617: <# 153> unplug requested unplug (0) No such device on
e004:5001 so clear socket
enbd-client 11616: client (-1) opens device /dev/nda
enbd-client 11617: client (0) last error No such device
enbd-client 11616: <# 296> managersighandler received signal 17
enbd-client 11616: sighandler relaunches child from manager
enbd-client 11616: client (-1) reaped dead child 11617
enbd-client 11616: client (-1) manager launched daemon 0 (11619) for
e004:5001
enbd-client 11616: client (-1) childminder launched pid 11619 (0)
enbd-client 11619: client (0) opens device /dev/nda1
enbd-client 11619: client (0) opened device /dev/nda1 ok
enbd-client 11619: client (0) opened socket 5 to e004:5001
enbd-client 11619: client (0) read passwd ok from e004:5001
enbd-client 11619: client (0) got cliserv magic ok from e004:5001
enbd-client 11619: client (0) got a signature ok from e004:5001
enbd-client 11619: client (0) begins main loop


This is from the enbd-2.4.32, which is currently on the web.
