The command 'rm' segfaulted. I can still reboot the machine with the command "/sbin/reboot -f -n". The file system, all of it it seems, can still be accessed from the other nodes. On the node where the segfault appeared the directory /ceph (the mount point) can be accessed but not the directory /ceph/tmp (into which I was writing the files). When the segmentation fault appeared on the node I was launching the commands from I got the output below. --jerker bash: line 1: 14100 Segmentation fault rm -f tmp.xp2 KNOPP.bench.xp2 Message from syslogd@ at Fri Nov 7 21:11:17 2008 ... xp2 kernel: ------------[ cut here ]------------ Message from syslogd@ at Fri Nov 7 21:11:17 2008 ... xp2 kernel: invalid opcode: 0000 [#1] SMP Launching on xp7...
