Re: [RndTbl] REQ: Volunteer of a Clonezilla Guru for one day (maybe less)
Check your syslogs on the nfs server. Might be getting a permission error somewhere. Sean On 2011-04-10, at 6:53 AM, Robert Dyck <rbdyck2@shaw.ca> wrote:

You can also modify the small linux system that gets shoved to the clients - I had to change it at one point because of video drivers. This might allow you get a console on the machine. I'm assuming you've tried to hit alt+f1 etc to switch to a console and it didn't work? Also, is it specific machines that cause this reaction, or is it sporadic?

It was sporadic. Last Friday one of our team tried to network boot 3 IBM ThinkCentres. One successfully connected to Clonezilla, the other two had this problem. Then we corrected the IP address in dhcpd.conf on the router and rebooted it. When Lawrence tried to start Clonezilla again, all three machines got the error. I had also tried to change node name: we set the machine name for the Clonezilla server to "clonezilla" but the install script set the node name for DRBL to "drbl". So we tried to change the node name in dhcpd.conf on the clonezilla server to "clonezilla", then restart the machine. That didn't change any behaviour. The node name may be stored elsewhere, so to make it consistent we changed it back to "drbl" and changed the machine name to also "drbl". So that server now has a consistent machine name. No observed change in behaviour. However, after all this messing around it now consistently fails. I didn't try alt-F1, but then I didn't install the GUI on the server. It's strictly CUI. The router is actually running Fedora, the Clonezilla server is running Ubuntu Server 10.10 Maverick. The client does get to a command prompt when it halts. I did try "ls" and it does show the file system of the server. That's the other thing: why does it give an error about failure to mount a file system when it does get the file system?

On the client, boot it up and do a dmesg. This is specific to that client - not the server. That should tell you whats going on - that would be my first step. Without knowing whats going on with the client its hard to diagnose a problem. Rob On Sun, Apr 10, 2011 at 11:50 AM, Robert Dyck <rbdyck2@shaw.ca> wrote: > It was sporadic.
