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 lustre01@tcp0:/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?
