Package: nbd-server
Version: 1:2.9.11-3
In an automatic test system (used by xen upstream) I encountered this
failure:
Jan 25 16:12:36 leaf-beetle nbd_server[20034]: Read failed: Bad address
Jan 25 16:12:36 leaf-beetle nbd_server[20033]: Child exited with 1
The client naturally then saw a series of IO failures and was
generally very unhappy.
The problem is not easily reproducible. I have seen similar failures
before but they are very infrequent.
The configuration in this case was:
* Two NBDs: each one of an LVM volume on the server imported by the client
* Each LVM VG backed by a single PV on a physical disk partition
* Both hosts' hardware: rackservers.com AMD-based server
* Both hosts' userland: amd64 lenny userland
* Both hosts' kernel: Xen-enabled xen.org kernel derived from 2.6.32.27
* Both hosts' hypervisor: xen-unstable 4.1.0 RC2+
* nbd server hostname: leaf-beetle
* nbd client hostname: potato-beetle
Full logs can be found here for the next few weeks:
http://www.chiark.greenend.org.uk/~xensrcts/logs/5238/test-amd64-amd64-pair/info.html
I appreciate that this isn't very much to go on. If you would like to
suggest some additional instrumentation, or additional logs to
capture, I will be happy to add that to my test machinery and then
report the results as and when the bug recurs.
Thanks,
Ian.
Here is a copy of the /etc/nbd-server/config from the server:
