Hello,
At the moment (with the kernel-builtin infiniband module mlx4 etc. -
running 2.6.32-431.23.3.el6-lustre) I get the following error, while
loading the LNet-Module:
> LNetError: 4554:0:(o2iblnd.c:2657:kiblnd_dev_failover()) Failed to
> bind ib0:10.69.100.5 to device((null)): -2
> LNetError: 4554:0:(o2iblnd.c:2800:kiblnd_create_dev()) Can't
> initialize device: -2
> LNetError: 105-4: Error -100 starting up LNI o2ib
> LustreError: 4554:0:(events.c:808:ptlrpc_init_portals()) network
> initialisation failed
It seems this error has its starting point in the function
"ib_get_cached_gid".
Where should I start to resolve that error? Any help appreciated...
