[SSI-devel] unixnm.c oops

[Roger T. <rog...@gm...>]

I'm using SSI-1.2.2-Lustre-1.2.4 with Laura's IPC patch and crashed
the whole cluster today.  My root filesystem is not NFS exported, but
seems like whenever the whole cluster crashes the CFS hard mount would
need a manual fsck even when it is a journaling fs.  This is a UP
kernel for P3/Coppermine with highmem.

The initnode crashed so bad I didn't get any response on the console.=20
The failover node got into kdb however.  This is what I have on the
failover node, and haven't reboot the failover node yet.

The following is from node 2.
