We shouldn't be able to do anything that can affect a kill -9. However, if you want to see what it is stuck on, doing a 'echo t > /proc/sysrq-trigger' and finding the fileserver process in syslog would probably help say where exactly it's stuck (or crashtool, depending on what distro you're on). You could also try looking at the userspace stack with pstack or gdb, but I'd expect you may have trouble getting anything useful out of the problematic thread if it won't come out of D. -- Andrew Deason [email protected] _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
