Hi, We're having great difficulty getting all clients in an LTSP lab to boot up consistently, it appears to be related to the new nbd-proxy? Here's the report our tech that builds the LTSP servers for us gave me...
===== When 2 or more switches are between client and server a failure to boot occurs before launching LDM about %50 of the time. The frequency of the failure to boot is reduced by being connected to the server with only one intermediate switch but does not go away completely. The following bugs seem to reference the same problem and indicate that it is nbd-proxy that is falling down during the boot process. https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/604314 https://bugs.launchpad.net/ltsp/+bug/589034 The latter of these references a patch that when applied disables the activation of the nbd-proxy during the client setup process. My success rate for booting clients after applying this patch rises to about %70. Load seems to effect this condition adversely as well as speed and duplex transitions such as many 10/100 clients connecting to a server attached to a gigabit port. The clients in question are Atom based and include gigabit ethernet ports but are connected to 10/100 ports in the classroom. Switches being used include HP Pro-curve edge products as well as a variety of unmanaged 10/100 5-8 port switches. ===== We had none of these problems in 9.04. Are any of the developers listening on this aware of this and possibly working on it? I have posted our experiences on Launchpad, but there's no indication of anything happening. School starts here in about 4 weeks and this is bad enough that we're considering rolling back to 9.04. There are nice new features in 10.04 I'd like to give folks access to, but I don't want folks to have to reboot clients multiple times to get them to come up...
