Re: [Lustre-discuss] b1_8 patchless client on 2.6.30

2009-10-16 Thread Patrick Winnertz 
Hey

 Up to 2.6.28 vanilla kernels, mounting lustre on a patchless client with
  b1_8 is fine. Why do I see errors about 'unknown type: mgc' on the client
  side with 2.6.30?
When I remember correctly one module is not loaded automatically, try prior 
loading the module mgc by hand (modprobe mgc) then try again.

Greetings
Winnie

Thanks, Winnie, that's it! Nice to have a client with vanilla 2.6.30 now.

Bye, Ralf

[Lustre-discuss] b1_8 patchless client on 2.6.30

2009-10-15 Thread Ralf Utermann 
Dear list,

with  patch https://bugzilla.lustre.org/attachment.cgi?id=26155 and fixing
one last compile error (https://bugzilla.lustre.org/show_bug.cgi?id=19720#c28),
I get b1_8 to compile and load the client modules on vanilla 2.6.30.9.

However, mounting the lustre filesystem gives the following error:

[ 3761.916501] Lustre: OBD class driver, http://www.lustre.org/

Up to 2.6.28 vanilla kernels, mounting lustre on a patchless client with b1_8 
is fine.
Why do I see errors about 'unknown type: mgc' on the client side with 2.6.30?
