| |
I hit an obscure bug last night when trying to copy files from an nfs client to my nfs server. The server is a P3/800 with three IDE disks in software RAID5 running vanilla 2.6.10 and Debian Sarge. The network is local 100Mbit/s switched ethernet. The server exports a 220 gig partition which contains a lot of data.
Oh, kernel configs and stuff from the server can be found from: http://www.holviala.com/~kimmy/crash/
Anyway, I mount the export to a Linux client (tried with a few with different 2.6 kernels and distros) and then start copying files from clients CDROM to the server through NFS. After copying a few small files, the first big one reboots the server. There are no log entries, and the server has no local console so I don't know what happens. This is reproduceable 100% of the time.
To narrow down the problem, I've tried the following:
- copied files from a different client running Gentoo: reboot - exported a non-raided partition (hdc9) and tried that: reboot - switched 2.6.10 to 2.6.11-rc3: reboot, but it took longer
I hope it's just something that I've done, but this server has been in use for a long time now without any problems, and I haven't touched it for a while.
So, if anyone knows what's wrong, or can tell me a way to debug the situation more I'd be grateful. The server is in a place where it's nearly impossible to have a local console - I could probably use a serial one if necessary for debugging.
