Lustre discuss - Mar 2008 - kernel: LustreError: 7025:0:(client.c:519:ptlrpc_import_delay_req())

I''m seeing kernel messages from my three OSS machines and
don''t know
what they mean.  These messages started after a orderly shutdown of all 
my machines over the weekend for a new UPS install.  All the OSSes are 
logging the same error.

kernel: LustreError: 7025:0:(client.c:519:ptlrpc_import_delay_req()) @@@ 
IMP_INVALID  req at ffff81011ce20600 x56653/t0 
o101->MGS at MGC10.149.0.137@o2ib_0:26 lens 232/240 ref 1 fl Rpc:/0/0 rc 0/0

Is there something that I need to do to eliminate these?  The filesystem 
appears to be completely functional otherwise.

The run environment is lustre 1.6.4.2 on SLES 10.

Thanks,
Bill

I''ll attempt to answer my own question here.

It appears that because the OSSes were started before the MDS that these 
nodes are still trying to obtain MGS data from that host but even though 
it came back, they still can''t.  This appears to be bug # 13715.

A few weeks from now I''ll be able to restart the lustre OSSes and see
if
this corrects the problem.
