Sorry for re-posting. I didn't format the previous post well.
Dear all,
I installed lustre-1.6.0.1 patchless client on a machine with
linux-2.6.16.x86_64 kernel. The machine
has 64 bit AMD CPU. I started all
servers on another node(also running lustre-1.6.0.1, but using
linux-2.6.12
kernel). The servers started OK. But when I tried to mount to the server from
the
patchless client using "mount -t lustre [EMAIL PROTECTED]:/spfs
/mnt/testfs", the client crashed and gave me
the following error messages.
I've tried for a lot of time to figure it out but failed. Did anyone else meet
with the situation?
